.................. | Section 20.106, "Radioactivity in Effluents to Unrestricted Areas," of the Nuclear Regulatory Commission's regulations in 10 CFR Part 20, "Standards for Protection Against Radiation," estab- lishes limits on concentrations of radioactive material in effluents to unrestricted areas. | ||
1. | |||
Paragraph (c) of 5 20.1, "Purpose," of 10 CFR Part 20 states that licensees s;hould, in addition to complying with the limits set forth in that part, make every reasonable effort to maintain releases of radioactive materials in effluents to unrestricted areas as far below the limits specified as is reasonably achievable. | |||
Sections 50.34a, "Design Objectives for Equipment to Control Releases of Radioactive Material in Effluents -- Nuclear Power Reactors," and 50.36a, "Technical Specifications on Effluents from Nuclear Power Reactors," of 10 CFR Part 50, "Licensing of Production and Utilization Facilities," | |||
set forth design objectives and technical specifications to control releases of radioactive efflu- ents from light-water-cooled nuclear power reactors. Section 50.36a of 10 CFR Fart 50 further provides that, in order to keep power reactor effluent releases as low as is reasonably achiev- able, each operating license will include technical specifications that (a) require compliance with the provisions of § 20.106 dealing with effluent discharge limits, (b) require that operating procedures for the control of effluents be established and followed and that eqi ipment installed in the radioactive waste system be maintained and used, and (c) establish re( :,-ements for reporting measured releases of radionuclides to the environment. | |||
Appendix I, "Numerical Guides for Design Objectives and Limiting Conditions for Operation to Meet the Criterion 'As Low As Is Reasonably Achievable' for Radioactive Material in Light- Water-Cooled Nuclear Power Reactor Effluents," to 10 CFR Part 50 provides numerical guidance for radioactive effluent design objectives and technical specification requirements for limiting conditions of operation for light-water-cooled nuclear power plants. | |||
To implement Appendix I, the NRC staff has developed a series of guides that provide methods acceptable to the staff for the calculation of preoperational estimates of effluent releases, dispersion of the effluent in the atmosphere and different water bodies, and estimation of the associated radiation doses* to man. This guide describes basic features of these calculational models and suggests parameters for the estimation of radiation doses to man from effluent releases. | |||
The methods used herein are general approaches that the NRC staff has developed for application in lieu of specific parameters for individual sites. The use of site-specific values by the applicant is encouraged. However, the assumptions and methods used to obtain these parameters should be fully described and dncumented. | |||
The procedures and models provided in this guide will be subject to continuing review by the-staff with the aim of providing greater flexibility to the applicant in meeting the require- ments of Appendix I. As a result of such reviews, it is expected that alternative acceptable methods for calculation will be made available to applicants and that calculational procedures found to be unnecessary will be eliminated. | |||
This guide supersedes portions of Regulatory Guide 1.42, Revision 1, "Interim Licensing Policy on as Low as Practicable for Gaseous Radioiodine Releases from Light-Water-Cooled Nuclear Power Reactors," which is being withdrawn. | |||
==B. DISCUSSION== | ==B. DISCUSSION== | ||
... | Appendix I to 10 CFR Part SO provides guidance on the levels of exposure of the general public resulting from effluent releases that may be considered to be as low as is reasonably achievable. This guide describes basic features of the calculational models and assumptions in use by the NRC staff for the estimation of doses. These estimates can be used to implement Appendix I in lieu of site-specific phenomena actually affecting the estimation of radiation exposure. | ||
1.109-7 | |||
In this guide, the term "dose," when applied to individuals, is used instead of the more precise term "dose equivalent," as defined by the International Commission on Radiological Units and Measurements (ICRU). | |||
1.109-7 | |||
Appendix A of this guide describes suggested methods for calculating the estimated doses to man from discharges to the hydrosphere. Appendix B of this guide describes suggested models and assumptions for calculatinr submersion doses from radionuclides discharged to the atmosphere, and Appendix C gives equations for estimating doses from radioiodines and other radionuclides released to the atmosphere. Appendix D describes the models and assumptions for calculating population dose (man-rem and man-thyroid-rem) from radionuclide releases to the atmosphere and hydrosphere. | |||
The models and assumptions described in Appendices A, B, C, and D of this guide are accept- able to the NRC staff for calculating doses to individuals and populations. If other models are selected, they should include the same exposure pathways and physical mechanisms as are used in the models described in this guide. | |||
As discussed in Section III.A.2 of Appendix I to 10 CFR Part 50, the applicant may take into account any real phenomena or actual exposure conditions that affect or modify the estimate of radiation exposure. Such conditions should include actual values for agricultural productiv- ity, residence times, dose attenuation by structures, measured environmental transport factors (suchas bioaccumulation factors), or similar values actually determined at a specific site. | |||
The applicant should provide e-ough information on the measurements or other methods used to derive these substitute values to enable the NRC staff to evaluate their validity. | |||

APPENDIX A | |||
METHODS FOR CALCULATING DOSES TO MAN FROM RADIONUCLIDE | |||
DISCHARGES TO THE AQUATIC ENVIRONMENT | |||
The equations for estimating radiation exposure to man from four principal exposure path- ways in the aquatic environment (potable water, aquatic foods, shoreline deposits, and irrigated foods) are listed in Section C, "Regulatory Position," of this guide. The equations can be used to calculate the annual doses to various organs of a child, 0 - 11 years; a teen, 12 - 18 years; | |||
and an adult, 18+ years. | |||
1. Equation for Calculating Radiation Dose via Liquid Pathways Equa*tion (A-l) is the fundamental equation for calculating the radiation dose to man via liquid effluent pathways. | |||
aipj C ip Uap aipj (A--) | |||
where Cip is the concentration of nuclide i in the media of pathway p, in pCi/kg; | |||
Dai is the dose factor which is specific to a given radionuclide. i, pathway p, organ j, and individual's age a. It represents Lhe annual dose due to the intake of a radionuJide, in mrem/pCi, or from exposure to a given concen- tration of a radionuclide in water, in mrem per hr/pCi per liter; | |||
Raip is the annual dose to organ j of an individual of age a from nuclide i via apip pathway p, in mrem/yr; and Uap is the exposure time or intake rate (usage) associated with pathway p for lap .ge group a, in hr/yi or kg/yr (as appropriate). | |||
The three factors making up Equation (A-1) are discussed in the following sections, most of which were taken directly from the WASA-1258 report (Ref. 1). (An updated version of the portion of the WASH-1258 report describing models and computer programs is contained in the BNWL-1754 report (Ref. 2).) | |||
a. Concentration in Environmental Media (Cip) | |||
The points at which concentrations in environmental media of interest should be evaluated are shown in Table A-1. The concentrations can be estimated from the mixing ratio Mp , the bio- accui;ýulation factor Bip, the radionuclide release rate Qi, and other terms presented in the path- way equations that appear later in this discussion. | |||
b. Usageý (Uap) | |||
The second term of Equation (A-l) is the usage term Uap. Usage is expressed as a consumption rate in kg/yr or liters/yr or as an exposure time in hr/yr, as appropriate for the pathway p and age group a under consideration. | |||
The NRC staff encourages the use of site-specific data, whenever possible, for param- eters such as those included in Table A-2. Such data should be documented. In the absence of site-specific data, however, the usage values (consumption rates and exposure times) presented in Table A-2 are reconmnended.* | |||
In selecting usage values, not only the present land and water uses should be considered, but also changes in land and water uses made possible by such activities as chemical pollution abatement. Radioactive material released into waterways may include long-lived radionuclides that have potential for accumulation in sediments and biota and may persist for many years -- | |||
perhaps beyond the lifetime of the nuclear power station. | |||

C. Dose Factor (Daip.) | |||
Equations for calculating internal dose factors are derived from those given by the International Corninission on Radiological Protection (ICRP-Ref. 15) for body burden and ma):imur permissible concentration (r.IPC). Effective absorbed energies for the radionuclides are calcu- lated from the ICRP model. Appendix D of Reference 16 was used as a basic source of age-dependent dose factors for ingestion. Where data are lacking, metabolic parameters for the Standard M~an were used for other ages as well. | |||
The dose factors for external exposure were based on the assumption that the con- taminated medium is large enough to be considered an "infinite volume" relative to the range of the emitted radiations. Under this assumption, the energy emitted per gram of medium is equiva- lent to the energy absorbed per gram of medium corrected for the differences in energy absorption between air or water and tissue and for the physical geometry of each specific exposure situation. | |||
Material deposited from sedimentation in an aquatic systet, or from irrigation water onto the ground represents a fairly large, nearly uniform thin sheet of contamination. The factors for converting surface contamination given in pCi/m 2 to the annual gaisia dose at one meter above a uniformly contaminated plane have been described by Soldat and others (Refs. 4, 5, and 17). Dose factors for exposure to soil sediment have units of mnrern/hr per pCi/1n2 surface. | |||
A set of dose factors for 45 radionuclides was originally calculated for the year 2000 | |||
model (Ref. 4). These factors have since been recalculated using recent decay scheme informia- tion (Ref. 18) and expanded to include additional radionuclides. The revised list is given in Tables A-3 through A-7; it contains several radionuclides for which the daughter is not listed separately (e.g., Ru-Rh-106, Cs-137-Ba-137m, and Ce-Pr-144). In those instances, the daughter's decay energy has been included in the factor. | |||
2. Equations for Liquid Pathways This section develops the set of equations required for the liquid pathway m:iodel. Tie principal difference betveen pathways is the manner in which the radionuclide concentrations are calculated. The doses from the four pathways should be added to determine the total dose. | |||
a. Potable Water The annual dose from ingestion of water is calculated from Equation (A-2) below: | |||
Rapj = 1100 Uap Qjexp(-x. .t )Daipj (A-2) | |||
apF 1 p aipj Symbols for this equation were defined earlier, in Section C.] of this guide. | |||
The sunmation process adds the dose contribution from each nuclide to yield the total dose for the pathway-organ combination selected. The Q!/F termis in Equation (A-2) define the concentration of nuclide i in the effluent at the point of discharge. The expression (QMM /F)exp(-A t ) yields the concentration of nuclide i at the time the water is consumed. | |||
I pconcentration This i p is the term Cip in Equation (A-1). As a minimum, the transit time tp may be set equal to 12 hours to allow for radionuclide transport through the water purification plant and the water distribution system. The transit time should be increased as appropriate to allow for travel from the point of effluent release to the water purification plant intake. Credit may be taken for radionuclide removal by water purification processes using techniques such as those outlined in Reference 4. | |||
It should be noted that, depending on the hydrological dispersion model employed, the mixing ratio, M'Ip,or dilution factor may not be explicitly defined. In those instances (e.g., | |||
buildup of activity in a cooling pond), the relative concentration in the mixed stream (compared to the effluent concentration) may be supplied as a function of the radiological decay constarnt. | |||
with any potential effluent recycling taken into account. Suggested hydrological dispersion ,:odels will be contained in another regulatory guide now under preparation on the subject of methods for estimating aquatic dispersion of liquid effluents from routine reactor releases for the purpose uO | |||
implementing Appendix I. | |||
b. Aquatic Foods The concentrations of radionuclides in aquatic foods are directly related to the concentrations of the nuclides in water. Equilibrium ratios between the two concentrations, | |||

called bioaccumulation factors in this guide, can be found in the literature (Pnf. 19). The addition of the bioaccumulation factor Bip to Equation (A-2) yields Equation (A-3), which is suitable for calculating the internal dose for consumption of aquatic foods. | |||

, p Values of Bip are given in Table A-8; the other parameters have been previously defined. | |||
The transit time tp may be set equal to 24 hours to allow for radionuclide decay during transit through the food chain, as well as during food preparation. | |||
c. Dose from Shoreline Deposits The calculation of individual dose from shoreline deposits is complex since it involves estimation of sediment load, transport, and concentrations of radionuclides associated with suspended and deposited materials. One method of approaching this problem was presented in the Year 2000 Study (Refs. 4, 17, 20, and 21). Based on these references, an estimate of the radio- nuclide concentration in shoreline sediments can be obtained from the following expressions: | |||
C.s Kc Ciw[l | |||
1w - exp(-.it)] | |||
i (A-4) | |||
isc where Cis is the concentration of nuclide i in sediment, in pCi/kg; | |||
CiW is the concentration of nuclide i in water adjacent to the sedinent, in pCi/liter; | |||
Kc is an assumed transfer constant from water to sediment, in liters/kg per day; | |||
t is the length of time the sediment is exposed to the contaminated water, nominally 15 years (approximate midpoint of facility operating life), in hours; and Ai is the decay constant* of nuclide i, in hours-l. In the original evaluation of the equation, Xi was chosen to be the radiological decay constant, but the true value should include an "environmental" removal constant. | |||
The value of Kc was derived for several radionuclides by using data from water and sediment samples collected over a period of several years in the Columbia River between Richiand, Washington, and the river mouth and in Tillamook Bay, Oregon, 75 km south of the river mouth (Refs. 22 and 23). Since the primary use of the equation is to facilitate estimates of the exposure rate from gamma emitters nn*wmeter above the sediment, an effective surface contamina- tion was estimated. This surface contamination was assumed to be contained within the top 2.5 cm (I in.) of sediment.** The dose contribution from the radionuclides at depths below 2.5 cri was ignored. The resulting equation is Si 1 iCi WDl MOT - exp(-Ait)] (A-5) | |||
where Si is the "effective" surface contamination, in pCi/m2, that is used in subsequent calculations; | |||
If the presence of a radionuclide in water and sediment is controlled primarily by radioactive equilibrium with its parent nuclide, the water concentration and decay constant of the parent should be used in Equations (A-4) and (A-5). | |||

d. Dose from Foods Grown on Land Irrigated by Contaminated Water The equations in the following paragiaphs can be used to calculate doses from radio- nuclides in irrihjated crops. Separate expressions are presented for tritium because of its unique environmental behavior. | |||
(1) Vegetation The concentration of radioactive material in vegetation results from deposition onto the plant foliage and from uptake from the soil of activity deposited on the ground. The rmodel used for estimating the transfer of radionuclides from irrigation water to crops through water deposited on leaves and uptake from soil was derived for a study of the potential doses to people from a nuclear power complex in the year 2000 (Ref. 4). | |||
The equation for the model (for radionuclides except tritium) is presented below in slightly modified form. The first term in brackets relates to the concentration derived from direct foliar deposition during the growing season. The second term relates to uptake from soil and reflects the long-term deposition during operation of the nuclear facility. Thus for a uniform release rate, the concentration Civ of radionuclide i in the edible portion of crop species v, in units of pCi/kg, is given by: | |||
(A-8 ) | |||
iv i" - exp(- '"U t e)]v Biv[I - ex 1(-'P 'itb)1]exp(-..it ) | |||
The de;,osition rate, di, from irrigated water is defined by the relation d'i = Ciw (water deposition) (A-9) | |||
I where Ciw is the concentration of radionuclide i in water used for irrigation, in pCi/liter, and I is the irrigation rate, in liters/m2 /hr; i.e., volume of water (liters) | |||
sprinkled on unit area of field in 1 hour. | |||
For tritium, the equation for estimating Civ is (see Ref. 25): | |||
Cv M Ctl (A-10) | |||
For a cow grazing on fresh forage, te in Equation (A--8) is set equal to 720 hours | |||
(30 days), the typical time for a cow to return to a particular portion of the grazing site. | |||

(2) Animal Products The radionuclide concentration in an animal product such as meat or milk is dependent on the amount of contaminated feed or forage eaten by the animal and its intake of contaminated water. The radionuclide concentration in animal products CiA in terms of pCi/liter or pCi/kg (Ref. 4) is proportional to the animal's intake of the radionuclide in feed or forage (subscript F) and in water (subscript w): | |||
CiA = F iAECiFQF + CiAwQAw] (A-li) | |||
The second set of terms in the brackets in Equation (A-1l) can be omitted if the animal does not drink contaminated water. Values for QF and QAw are presented in-Table A-i1. | |||

In actual use, it will be necessary to compute separately the milk and meat portions of the dose due to animal products (also applicable to Equation (A-17)). | |||

MODELS FOR CALCULATING DOSES FROM | |||
NOBLE GASES DISCHARGED TO THE ATMOSPHERE | |||
The following analytical models are used for calculating doses from exposure to gaseous effluents. Separate models are given for air and tissue doses due to gamma and beta rays. | |||
Except for the case of noble gas doses resulting from elevated releases, all models assume submersion in an infinite cloud at the exposure point. | |||
1. Annual Gamma Air Dose from Elevated Releases of Noble Gases Slade (Ref. 1) describes the derivation of the equations for estimating annual air doses from photon emitters dispersed in the atmosphere. The following expression can be used for calculating annual doses: | |||
D 260 | |||
n un s I )1 Dik Symbols for this equation were defined earlier, in Regulatory Position C.2.a of this guide. | |||
The photons were combined into energy groups, and each photon intensity within a group was weighted by its energy and energy absorption coefficient. Thus, the effective fraction of disintegrations of the nuclide i yielding photons corresponding to the photon energy group k, Aki, was determined to be Aki I [AmEmpa(Em)]/[Ekwa(Ek)] (B-2) | |||
m where A is the fraction of the disintegrations of nuclide i yielding photons m of energy E | |||
Em is the energy of the mth photon within the kth energy group, in MeV; and Ua (Em) is the energy absorption coefficient in air associated with the photon energy Em, in m All other parameters are as previously defined. The summation is carried out over all photons within energy group k. Data for the photon energies and abundances for most of the noble gas nuclides were taken from Reference 2. For radionuclides not contained in Reference 2, data were obtained from Reference 3. | |||
Decay during travel from the point of release to the receptor is QD = Q* exp(-Xir/un) (B-3) | |||
The term "gamma air dose" refers to the components of the air dose associated with photons emitted during nuclear and atomic transformations, i.e., gamma and x-rays. Annihilation and bremsstrahlung photon radiations are possible contributors to this compunent of the air dose. | |||
Elevated release conditions are assumed to occur when the point of release is higher than twice the height of adjacent solid structures. (See Regulatory Guide 1.111, "Methods for Estimating Atmospheric Transport and Dispersion for Gaseous Effluents in Routine Releases from Light- Water-Cooled Reactors.") | |||
1.109-30 | |||
where Qi is the initial release rate of nuclide i, in Ci/yr, and | |||
1 Ai is the decay constant of nuclide i, in sec" | |||
All other parameters are as previously defined. | |||
2. Annual Gamma Air Dose from Ground-Level Releases of Noble Gases and Annual Beta Air Dose Plumes of gaseous effluents are considered semi-infinite in the case of noble gases released from vents. The concentration of the radionuclides in air at the receptor location may be determined from atmospheric dispersion model described in Regulatory Guide 1.111. | |||
The annual average ground-level concentration of gaseous effluent species i at location (r,o) | |||
from the release point is determined from xi(ra) = 3.17 x 104 Q*[x//Q' 1D(r,o) (6-4) | |||
where xi(r,e) is the annual average ground-level concentration of nuclide i at the distance r in the sector at angle 0 from the release point, in pCi/m 3 , and | |||
[/Q')1D(r,o) is the annual average gaseous dispersion factor (corrected for radioactive decay) in the sector at angle e at the distance r from the release point,. | |||
in sec/mi3 The constant 3.17 x lO4 represents the number of pCi per Ci divided by the number of seconds per year. All other parameters are as previously defined. | |||
The annual gamma or beta air dose associated with the airborne concentration of the effluent species is then I | |||
DY(r,e) or DO(r,e) = xi(re)(OF* or DFO) (B-a) | |||
where the terms are as defined in Regulatory Position C.2.b. | |||
Table B-1 presents a tabulation of the dose factors for the noble gases and daughters of interest. | |||
3. Annual Dose to Tissue from Noble Gas Effluents It is also necessary to determine annual doses to real individuals in unrestricted areas. The staff computes the total body dose from external radiation at a depth of 5 cm into the body and the skin dose at a depth of 7 mg/cm2 of tissue. | |||
a. Elevated Releases The annual total body dose is computed as follows: | |||
DT(r,O) = 1.11 x SF I DI(re)exp[-i (Ek)t] (B-6) | |||
Ground-level release conditions are assumed to exist when the release point is less than or equal to twice the height of adjacent solid structures and the vertical exit velocity is less than five times the horizontal wind speed. (See Regulatory Guide 1.111.) | |||
The term "beta air dose" refers to the component of the air dose associated with particle emissions during nuclear and atomic transformations, i.e., 0+, B-, and conversion electrons. | |||

Symbols for this equation were defined earlier in Regulatory Position C.2.c of this guide. The constant 1.11 represents the ratio of the energy absorption coefficient for tissue to that for air. | |||
The skin dose has two components, the ganmia and beta contributions. The skin dose rate is computed by DS(r,o) 1.11 x SFD Y(r,o) + 3.17 x 1041 Qi(x/Q']D (r,o)DFSi (8-7) | |||
1 Symbols for this equation were defined earlier in Regulatory Position C.2.d of this guide. | |||
The skin beta dose factors OFS were determined using the decay scheme source docu- ments cited above and the methods used in References 4, 5, and 6. | |||
b. Ground-Level Releases The annual total body dose is computed as follows: | |||
DT(r,o) = 1.11 x SF ýxi(rO)DFBi (B-8) | |||
Symbols for this equation were defined earlier in Regulatory Position C.2.e of this guide. | |||
The annual skin dose is computed as follows: | |||
Ds(r,o) - 1.11 x SFFZxi(r'e)DFi + xii(ro)DFSi (8-9) | |||
where D5 (r,e) is the annual skin dose due to immersion in a semi-infinite cloud in I1 the sector at angle e, at the distance r from the release point, in mrem/yr, and xi(ra) is the airborne concentration of radionuclide i at point (r,6), in pCi/m 3 . | |||

Qi is the annual release rate of nuclide i to the atmosphere, J'i/yr; | |||
t is the time period over which the accumulation is evaluated, which is 15 years (riid-point of plant operating life). This is a simplified method of approximating the average deposition over the operating lifetime of the facility; | |||

where D.j(r,*) | |||
is the annual dose to organ j from the ground plane concentration of nuclide ii i at the location (r,r,), in mrem/yr; | |||

2. Annual Dose from Inhalation of Radionuclides in Air The annual average airborne concentration of radionuclide i at the location (r,t!) -ith res- pect to the release point may be determined as Xi(r,o) 3.17 x 104QQ[X/Q'] D(r,) (C-4) | |||

3. Concentrations of Airborne Radionuclides in Foods The concentration of radioactive material in vegetation results from deposition onto the plant foliage and from uptake of activity initially deposited on the ground. The model used for estimating the transfer of radionuclides from the atmosphere to food products is six:ilar to the model developed for estimating the transfer of radionuclides from irrigation water given in Appendix A of this guide. | |||
For all radioiodines and particulate radionuclides, except tritium and carbon-14, the con- centrition of nuclide i in and on vegetation at the location (r,Q) is estimated using CV(rO) di(r,o) r[l - exp('AEite)] Biv[l - exp(-Ytb)]] exp(-1ith) | |||

See Regulatory Position C.l of tnis guide for definitions of terms. | |||
Carbon-14 is assumed to be in oxide form (CO and C02 ). The concentration of carbon-14 in vegetation is calculated by assuming that its ratio to the natural carbon in the vegetation is the same as the ratio of carbon-14 to natural carbon in the atmosphere surrounding the vegetation (see Refs. 1 and 2). | |||

This | This yields CV 4 (ro) = 3.17 x 107 Q74 [x/Q'](r,) 0.11/0.16 U | ||
= 2.2 x 107 Qi4 [x/Q'J(r,O) (C-8) | |||
where Cv 4 (r,O) is the concentration of carbon-14 in vegetation grown at location (r,e), in pCi/kg; | |||
!Q14 is the annual release rate of carbon-14, in Ci/yr; | |||
0.11 is the fraction of total plant mass that is natural carbon, dimensionless; | |||
0.16 is equal to the concentration of natural carbon in the atmosphere, in g/M 3 and | |||
3.17 x 107 is equal to (1.0 x 1012 pCi/Ci)(l.0 x 103 g/kg)/(3.15 x 107 sec/yr). | |||
The concentration of tritium in vegetation is calculated from its concentration in the air surrounding the vegetation. Using the method described in Reference 3, the NRC staff derived the following equation: | |||
CV(r,o) = 3.17 x 107 QT[X/QJ](r,O)(0.75)(0.5/H) | |||
= 1.2 x 10 7 Qi[X/Q'](re)/H (c-9) | |||
where Cv(r,o) is the concentration of tritium in vegetation grown at location (r,e), pCi/kg; | |||
H is the absolute humidity of the atmosphere at location (r,o) in g/m3 Qý is the annual release rate of tritium, Ci/yr; | |||
0.5 is the ratio of tritium concentration in atmospheric water to tritium con-- | |||
centration in plant water, dimensionless; and | |||
0.75 is the fraction of total plant mass that is water, dimensionless. | |||
= | The deposition rate from the plume is defined by: | ||
The | dC(r.o) = 1.1 x 108ai(r,e)Qj (C-10) | ||
where | |||
6 1 (r,O) is the relative deposition of nuclide i, considering depletion and decay in transit to location (r,O), in m"2 (see Regulatory Guide 1.111) and | |||
1.1 x 108 is the number of pCi per Ci (1012) divided by the number of hours per year | |||
(8760). | |||
For radioiodines the model considers only the elemental fraction of the effluent. The deposition should be computed only for that fraction of the effluent that is estimated to be elemental iodine. Measurements at operating facilities indicate that about half the radioiodine emissions may be considered nonelemental (Reference 4). With this consideration included, Equation (C-l0) for radioiodine becumes: | |||
I | |||
1.109-54 | |||
15.5 x Si(r,6)Q.107 (C-1l) | |||
and Q! is the total (elemental and nonelemental) radioiodine emission rate. The retention ictor r for elemental radioiodine on vegetation should be taken as unity, since the experimental mea- surement (References 5, 6, and 7) techniques used to evaluate this transfer mechanism consisted of direct comparison of the gross radioiodine concentration on vegetation and the concentration in air (References 8, 9, and 10). | |||
For radioiodines, the deposition model is based only on the dry deposition process. Wlet deposition, including "washout" of the organic and non-organic iodine fractions, should be con- sidered at some sites depending on the meteorological conditions (see Regulatory Guide 1.111). | |||
For particulates, the deposition model considers both wet and dry deposition. There is also a retention factor (r of Equation (C-7)) that accounts for the interception and capture of the deposited activity by the vegetative cover. A value of 0.2 is taken for this factor (References | |||
11 and 12). All nuclides except noble gases, tritium, carbon-14, and the iodines are treated as particulates. | |||

a. Parameters for Calculating Nuclides Concentrations in Veqetation Consumed by Man When the radionuclide concentration in vegetation directly ingested by man is estimated using Equation (C-7), the following parameters are used: | |||
Parameter Value | |||
2 Yv (vegetation yield) 2.0 kg/mi te (exposure time to plume) 60 days th (holdup after harvest) 1 day for garden-fresh leafy vegetables | |||
60 days for stored vegetables tb (soil exposure time) 15 years (midpoint of reactor operating lifetime) | |||
All other parameters in this equation are given in Regulatory Position C of this guide. | |||
b. Parameters for Calculating Nuclide Concentrations in Milk The radionuclide concentration in milk is dependent on the amount and contamination level of the feed consumed by the animal. The radionuclide concentration in milk is estimated a5 Cm(r,f): FmCiV(r,e)Q exp(-xit) (C-12) | |||
where C'(r,a) is the concentration in milk of nuclide i, in pCi/liter; | |||
CY(r,O) is the concentration of radionuclide i in the animal's feed, in pCi/kg; | |||
Fm is the average fraction of the animal's daily intake of radionuclide i which appears in each liter of milk, in days/liter (see Tables C-5 and C-6 for cow and goat data, respectively; for nuclides not listed in Table C-6, use the values in Table C-5); | |||

QF is the amount of feed consumed by the animal per day, in kg/day; | |||
t is the average transport time of the activity from the feed into the mil: | |||
and to the receptor (a value of 2 days is assumed); and Ni is the radiological decay constant of nuclide i, in days- Milk-producing animals are assumed to be on open pasture for the following grazing periods: | |||

(C-14) | |||
where C1ý(r~o) is the concentration of nuclide i in animal flesh, in pCi/kg; | |||
Ff is the fraction of the animal's daily intake of nuclide i which appears in each kiloaram of flesh, in days/kg (see Table C-5 for values); and t is the average time from slaughter to consumption, which is assumed to be | |||
20 days. | |||

MODELS FOR CALCULATING POPULATION DOSES FROM | |||
NUCLEAR POWER PLANT EFFLUENTS | |||
Calculation of the annual population-integrated total body and thyroid doses should be performed for the three effluent types identified in this guide. These doses should be evaluated for the population within a 50-mile radius of the site, as specified in paragraph D, Section II | |||
of Appendix I to 10 CFR Part 50. | |||
For the purpose of calculating the annual population-integrated dose, the 50-mile region should be divided into a number of subregions consistent with the nature of the region. These subregions may represent, for example, the reaches of a river or land areas over which the appro- priate dispersion factor is averaged. Dispersion factors, population data, and other information describing existing or planned uses of the subregions should be developed. | |||
1. General Expressions for Population Dose For pathways in which the permanent and transient population of the subregion can be con- sidered to be exposed to the average radionuclide concentrations estimated for the subregion, the annual population-integrated dose is calculated as follows: | |||

where Djda is the annual dose to organ j (total body or thyroid) of an average individual of age group a in subregion d, in mrem/yr; | |||
D is the annual population-integrated dose to organ j (total body or thyroid), | |||
i in man-rems or thyroid man-rems; | |||
fda is the fraction of the population in subregion d that is in age group a; | |||

The annual dose to the total body or thyroid of an average individual should be evaluated with the usage factors of Table 0-1. Models and equations for the detailed dose calculations are presented In Appendices A, B, and C of this guide. The annual population-integrated doses from ingestion of potable water, inhalation of airborne effluents, and external exposure to airborne or deposited radionuclides should be evaluated. | |||
For pathways that involve food products produced in the subregion, the food products may be distributed to other areas for consumption. For all the food that is produced within the | |||
50-mile radius, the radioactivity concentrations are averaged over the entire area by weiqhting the concentrations in each subregion by the amount produced in each subregion. This average concentration is used in calculating the population doses. The 50-mile average concentration of nuclide i in food p is computed as C = (/V ) exp(-Ait ) C v (0-2) | |||

All other factors are as defined above. | |||
Note that the above formulation limits the evaluation of the exposed population evaluation to the population residing within 50 miles as specified in paragraph D, Section II of Appendix I | |||
to 10 CFR Part 50. In calculating the annual population-integrated total body and thyroid doses, the current age distribution of the population within 50 miles may be assumed to be the same as the current age distribution of the U.S. population (see Reference for Appendix D). Models and equations for the detailed dose calculations are presented in Appendices A, B, and C. | |||
2. Use of the Models a. Population-Integrated Doses from Liquid Effluents The annual total body and thyroid population-integrated doses due to exposure to liq- uid effluents should be evaluated for the following principal pathways: potable water, aquatic food products, external irradiation from shoreline deposits, and terrestrial food products irri- gated with water that has received the liquid effluent. In addition to these pathways, other exposure pathways that arise from unique conditions at a specific site should be evaluated if they provide a significant* contribution to the annual dose received by an exposed population group. | |||
(1) Doses from Potable Water The annual population-integrated total body and thyroid doses from water consump- tion are evaluated for all subregions that have water intakes existing or designated at the time of the license application. The products of the individual doses and the population exposed in each such subregion within 50 miles from the site are summed to obtain the total dose. The formulation expressed in Equation (D-1) may be used. | |||
The total body and thyroid dose of the individuals should be evaluated using Ecuation (A-2) in Appendix A of this guide, together with the age-dependent usage factors Uap obtained from Table D-1. The dilution from the discharge point to the usage point should be evaluated using appropriate hydrological models for the various subregions. | |||
If the population served by a particular water supply system is not known, it can be estimated by the following: | |||
Pw = v/c (D-5) | |||
where c is the average daily usage of individuals on the system, in gal/day per person; | |||
Pw is the estimated population served by the water system; and v is the average'daily intake of the water supply system, in gal/day. | |||
If the industrial usage from the water supply system is known, it can be sub- tracted from the average daily intake of the system before this value is entered into Equation | |||
(0-5). | |||
For the purpose of this guide, any additional pathway is deemed to be significant if a conservative evaluation of the pathway yields an additional dose contribution equal to or greater than 10% of the total from all the pathways described here. Any pathway so identified should then be evaluated by a model similar to that used above. | |||
1. | 1.109-67 | ||
The population served by a water supply system whose intake is within the 50-mile radius may include individuals who reside outside the circle. This population may be pro-rated to include only the population within the 50-mile radius. Conversely, a water supply system with an intake beyond the 50-mile radius may serve the population within the 50-mile radius. | |||
Such exposed population should be included in the 50-mile population dose evaluation. | |||
(2) Doses from Food Products The annual population-integrated total body and thyroid doses from consumption of aquatic food products are evaluated using the production of sport and commercial harvests in the various subregions. The mixing ratio (or dilution) should be evaluated for each sub- region using an appropriate hydrological model. For sport harvests, the entire edible harvest is assumed to be ingested by the population within 50 miles. The formulation expressed by Equation (D-4) should be used with the population Pp given by the results of Equation (D-3). | |||
The age-specific ingestion factors of Table D-I may be used in lieu of site-specific data. | |||
For commercial harvests, the production within 50 miles from the site is con- sidered as part of the total U.S. harvest. Equation (D-2) should be used to compute the average concentration, with Vp as the total estimated U.S. commercial harvest of the aquatic food medium p. The annual population-integrated dose is then computed using Equation (D-4) with Pp = PSO" The age-specific factors of Table 0-1 may be used in lieu of site-specific data. | |||
(3) Doses from Shoreline Deposits The annual population-integrated total body and thyroid doses from recreational activities on the shoreline of the receiving water body are evaluated by sunmming the product of the individual doses in each subregion and the population exposed therein. All subregions within the 50-mile radius should be considered where existing or designated recreational facili- ties exist. If available, actual recreational usage in the vicinity of each facility should be used. The formulation of Equation (D-1) is appropriate. | |||
The | (4) Doses from Consumption of Terrestrial Food Products Irrigated by Waters Receiving the Liquid Effluent The annual population-integrated total body and thyroid doses from consumption of food irrigated with water from the body receiving the liquid effluent are evaluated following the procedures outlined in the development of Equation (0-4). Note that the term Vp of Equations | ||
(0-2) and (D-3) denotes the total production of food medium p within 50 miles, not just the total production of irrigated food medium p. The consumption rate data of Table D-1 may be used in lieu of site-specific data in the evaluation of Equation (D-4). | |||
b. Population-Integrated Doses from Airborne Effluents The annual total body and thyroid population-integrated doses should be evaluated for the following principal exposure pathways: noble gas submersion, inhalation of airborne efflu- ents, ingestion of contaminated terrestrial foods (milk, meat, and vegetation), and external irradiation from activity deposited on the ground. In addition to these pathways, other exposure pathways that arise from unique conditions at a specific site should be evaluated if they provide a significant contribution to the annual dose received by an exposed population group. (See Regulatory Position C.1 of this guide.) | |||
For the evaluation of exposures from atmospheric releases, the 50-mile region should be divided into 160 subregions formed by sectors centered on the 16 compass points (N, NNE, NE, etc.) | |||
and annuli at distances of 1, 2, 3, 4, 5, 10, 20, 30, 40, and 50 miles from the center of the facility. The atmospheric dispersion factors (x/Q') or similar factors should be evaluated at the radial midpoint for each of the subregions using appropriate atmospheric dispersion models such as those described in Regulatory Guide 1.111. | |||
(1) Doses due to Exposure to Noble Gases The annual population-integrated total body dose due to noble gas effluents should be evaluated by summing the products of the individual doses in each subregion and the population in each subregion. Equation (D-1) may be used. For external exposure, the model does E | |||
not differentiate between age groups. A structural shielding factor of 0.5,should be applied in conjunction with the dose factor data of Table B-1. | |||
1.109-68 | |||
(2) Doses due to Inhalation of Radlolodines and Particulates The annual population-integrated total body and thyroid doses from inhalation of airborne effluents should be evaluated by summing the products of the individual doses received in each subregion and the population in each subregion. Equation (D-1) may be used. | |||
The age-specific inhalation rates of Table D-1 may be used with the data of Tables C-l to C-4. | |||
(3) Doses due to Ingestion of Terrestrial Food Products The annual population-integrated total body and thyroid doses from ingestion of terrestrial food products should be evaluated using the production data for each subregion. | |||
Equation ( | For milk, meat, and commercial vegetables, the formulation of Equation (0-2) should be used to calculate the average concentrations in the foods. These concentrations are then used in Equation (D-4), along with the data of Tables D-1, D-2, and A-l to calculate population doses. | ||
(4) Doses due to External Irradiation from Activity Deposited o' the Ground The annual population-integrated total body and thyroid doses from external exposure to surface deposition of the effluent should be evaluated using Equation (D-l). A | |||
household shielding and occupancy factor of 0.5 should be applied in conjunction with the dose factors of Tables A-3 to A-7. | |||

A. INTRODUCTION
Section 20.106, "Radioactivity in Effluents to Unrestricted Areas," of the Nuclear Regulatory Commission's regulations in 10 CFR Part 20, "Standards for Protection Against Radiation," estab- lishes limits on concentrations of radioactive material in effluents to unrestricted areas.
Paragraph (c) of 5 20.1, "Purpose," of 10 CFR Part 20 states that licensees s;hould, in addition to complying with the limits set forth in that part, make every reasonable effort to maintain releases of radioactive materials in effluents to unrestricted areas as far below the limits specified as is reasonably achievable.
Sections 50.34a, "Design Objectives for Equipment to Control Releases of Radioactive Material in Effluents -- Nuclear Power Reactors," and 50.36a, "Technical Specifications on Effluents from Nuclear Power Reactors," of 10 CFR Part 50, "Licensing of Production and Utilization Facilities," set forth design objectives and technical specifications to control releases of radioactive efflu- ents from light-water-cooled nuclear power reactors. Section 50.36a of 10 CFR Fart 50 further provides that, in order to keep power reactor effluent releases as low as is reasonably achiev- able, each operating license will include technical specifications that (a) require compliance with the provisions of § 20.106 dealing with effluent discharge limits, (b) require that operating procedures for the control of effluents be established and followed and that eqi ipment installed in the radioactive waste system be maintained and used, and (c) establish re( :,-ements for reporting measured releases of radionuclides to the environment.
Appendix I, "Numerical Guides for Design Objectives and Limiting Conditions for Operation to Meet the Criterion 'As Low As Is Reasonably Achievable' for Radioactive Material in Light- Water-Cooled Nuclear Power Reactor Effluents," to 10 CFR Part 50 provides numerical guidance for radioactive effluent design objectives and technical specification requirements for limiting conditions of operation for light-water-cooled nuclear power plants.
To implement Appendix I, the NRC staff has developed a series of guides that provide methods acceptable to the staff for the calculation of preoperational estimates of effluent releases, dispersion of the effluent in the atmosphere and different water bodies, and estimation of the associated radiation doses* to man. This guide describes basic features of these calculational models and suggests parameters for the estimation of radiation doses to man from effluent releases.
The methods used herein are general approaches that the NRC staff has developed for application in lieu of specific parameters for individual sites. The use of site-specific values by the applicant is encouraged. However, the assumptions and methods used to obtain these parameters should be fully described and dncumented.
The procedures and models provided in this guide will be subject to continuing review by the-staff with the aim of providing greater flexibility to the applicant in meeting the require- ments of Appendix I. As a result of such reviews, it is expected that alternative acceptable methods for calculation will be made available to applicants and that calculational procedures found to be unnecessary will be eliminated.
This guide supersedes portions of Regulatory Guide 1.42, Revision 1, "Interim Licensing Policy on as Low as Practicable for Gaseous Radioiodine Releases from Light-Water-Cooled Nuclear Power Reactors," which is being withdrawn.
B. DISCUSSION
Appendix I to 10 CFR Part SO provides guidance on the levels of exposure of the general public resulting from effluent releases that may be considered to be as low as is reasonably achievable. This guide describes basic features of the calculational models and assumptions in use by the NRC staff for the estimation of doses. These estimates can be used to implement Appendix I in lieu of site-specific phenomena actually affecting the estimation of radiation exposure.
In this guide, the term "dose," when applied to individuals, is used instead of the more precise term "dose equivalent," as defined by the International Commission on Radiological Units and Measurements (ICRU).
1.109-7
Appendix A of this guide describes suggested methods for calculating the estimated doses to man from discharges to the hydrosphere. Appendix B of this guide describes suggested models and assumptions for calculatinr submersion doses from radionuclides discharged to the atmosphere, and Appendix C gives equations for estimating doses from radioiodines and other radionuclides released to the atmosphere. Appendix D describes the models and assumptions for calculating population dose (man-rem and man-thyroid-rem) from radionuclide releases to the atmosphere and hydrosphere.
The models and assumptions described in Appendices A, B, C, and D of this guide are accept- able to the NRC staff for calculating doses to individuals and populations. If other models are selected, they should include the same exposure pathways and physical mechanisms as are used in the models described in this guide.
As discussed in Section III.A.2 of Appendix I to 10 CFR Part 50, the applicant may take into account any real phenomena or actual exposure conditions that affect or modify the estimate of radiation exposure. Such conditions should include actual values for agricultural productiv- ity, residence times, dose attenuation by structures, measured environmental transport factors (suchas bioaccumulation factors), or similar values actually determined at a specific site.
The applicant should provide e-ough information on the measurements or other methods used to derive these substitute values to enable the NRC staff to evaluate their validity.

APPENDIX A
METHODS FOR CALCULATING DOSES TO MAN FROM RADIONUCLIDE
DISCHARGES TO THE AQUATIC ENVIRONMENT
The equations for estimating radiation exposure to man from four principal exposure path- ways in the aquatic environment (potable water, aquatic foods, shoreline deposits, and irrigated foods) are listed in Section C, "Regulatory Position," of this guide. The equations can be used to calculate the annual doses to various organs of a child, 0 - 11 years; a teen, 12 - 18 years;
and an adult, 18+ years.
1. Equation for Calculating Radiation Dose via Liquid Pathways Equa*tion (A-l) is the fundamental equation for calculating the radiation dose to man via liquid effluent pathways.
aipj C ip Uap aipj (A--) where Cip is the concentration of nuclide i in the media of pathway p, in pCi/kg;
Dai is the dose factor which is specific to a given radionuclide. i, pathway p, organ j, and individual's age a. It represents Lhe annual dose due to the intake of a radionuJide, in mrem/pCi, or from exposure to a given concen- tration of a radionuclide in water, in mrem per hr/pCi per liter;
Raip is the annual dose to organ j of an individual of age a from nuclide i via apip pathway p, in mrem/yr; and Uap is the exposure time or intake rate (usage) associated with pathway p for lap .ge group a, in hr/yi or kg/yr (as appropriate).
The three factors making up Equation (A-1) are discussed in the following sections, most of which were taken directly from the WASA-1258 report (Ref. 1). (An updated version of the portion of the WASH-1258 report describing models and computer programs is contained in the BNWL-1754 report (Ref. 2).)
a. Concentration in Environmental Media (Cip)
The points at which concentrations in environmental media of interest should be evaluated are shown in Table A-1. The concentrations can be estimated from the mixing ratio Mp , the bio- accui;ýulation factor Bip, the radionuclide release rate Qi, and other terms presented in the path- way equations that appear later in this discussion.
b. Usageý (Uap)
The second term of Equation (A-l) is the usage term Uap. Usage is expressed as a consumption rate in kg/yr or liters/yr or as an exposure time in hr/yr, as appropriate for the pathway p and age group a under consideration.
The NRC staff encourages the use of site-specific data, whenever possible, for param- eters such as those included in Table A-2. Such data should be documented. In the absence of site-specific data, however, the usage values (consumption rates and exposure times) presented in Table A-2 are reconmnended.*
In selecting usage values, not only the present land and water uses should be considered, but also changes in land and water uses made possible by such activities as chemical pollution abatement. Radioactive material released into waterways may include long-lived radionuclides that have potential for accumulation in sediments and biota and may persist for many years -- perhaps beyond the lifetime of the nuclear power station.

C. Dose Factor (Daip.)
Equations for calculating internal dose factors are derived from those given by the International Corninission on Radiological Protection (ICRP-Ref. 15) for body burden and ma):imur permissible concentration (r.IPC). Effective absorbed energies for the radionuclides are calcu- lated from the ICRP model. Appendix D of Reference 16 was used as a basic source of age-dependent dose factors for ingestion. Where data are lacking, metabolic parameters for the Standard M~an were used for other ages as well.
The dose factors for external exposure were based on the assumption that the con- taminated medium is large enough to be considered an "infinite volume" relative to the range of the emitted radiations. Under this assumption, the energy emitted per gram of medium is equiva- lent to the energy absorbed per gram of medium corrected for the differences in energy absorption between air or water and tissue and for the physical geometry of each specific exposure situation.
Material deposited from sedimentation in an aquatic systet, or from irrigation water onto the ground represents a fairly large, nearly uniform thin sheet of contamination. The factors for converting surface contamination given in pCi/m 2 to the annual gaisia dose at one meter above a uniformly contaminated plane have been described by Soldat and others (Refs. 4, 5, and 17). Dose factors for exposure to soil sediment have units of mnrern/hr per pCi/1n2 surface.
A set of dose factors for 45 radionuclides was originally calculated for the year 2000 model (Ref. 4). These factors have since been recalculated using recent decay scheme informia- tion (Ref. 18) and expanded to include additional radionuclides. The revised list is given in Tables A-3 through A-7; it contains several radionuclides for which the daughter is not listed separately (e.g., Ru-Rh-106, Cs-137-Ba-137m, and Ce-Pr-144). In those instances, the daughter's decay energy has been included in the factor.
2. Equations for Liquid Pathways This section develops the set of equations required for the liquid pathway m:iodel. Tie principal difference betveen pathways is the manner in which the radionuclide concentrations are calculated. The doses from the four pathways should be added to determine the total dose.
a. Potable Water The annual dose from ingestion of water is calculated from Equation (A-2) below:
Rapj = 1100 Uap Qjexp(-x. .t )Daipj (A-2)
apF 1 p aipj Symbols for this equation were defined earlier, in Section C.] of this guide.
The sunmation process adds the dose contribution from each nuclide to yield the total dose for the pathway-organ combination selected. The Q!/F termis in Equation (A-2) define the concentration of nuclide i in the effluent at the point of discharge. The expression (QMM /F)exp(-A t ) yields the concentration of nuclide i at the time the water is consumed.
I pconcentration This i p is the term Cip in Equation (A-1). As a minimum, the transit time tp may be set equal to 12 hours to allow for radionuclide transport through the water purification plant and the water distribution system. The transit time should be increased as appropriate to allow for travel from the point of effluent release to the water purification plant intake. Credit may be taken for radionuclide removal by water purification processes using techniques such as those outlined in Reference 4.
It should be noted that, depending on the hydrological dispersion model employed, the mixing ratio, M'Ip,or dilution factor may not be explicitly defined. In those instances (e.g., buildup of activity in a cooling pond), the relative concentration in the mixed stream (compared to the effluent concentration) may be supplied as a function of the radiological decay constarnt.
with any potential effluent recycling taken into account. Suggested hydrological dispersion ,:odels will be contained in another regulatory guide now under preparation on the subject of methods for estimating aquatic dispersion of liquid effluents from routine reactor releases for the purpose uO implementing Appendix I.
b. Aquatic Foods The concentrations of radionuclides in aquatic foods are directly related to the concentrations of the nuclides in water. Equilibrium ratios between the two concentrations,

called bioaccumulation factors in this guide, can be found in the literature (Pnf. 19). The addition of the bioaccumulation factor Bip to Equation (A-2) yields Equation (A-3), which is suitable for calculating the internal dose for consumption of aquatic foods.

, p Values of Bip are given in Table A-8; the other parameters have been previously defined.
The transit time tp may be set equal to 24 hours to allow for radionuclide decay during transit through the food chain, as well as during food preparation.
c. Dose from Shoreline Deposits The calculation of individual dose from shoreline deposits is complex since it involves estimation of sediment load, transport, and concentrations of radionuclides associated with suspended and deposited materials. One method of approaching this problem was presented in the Year 2000 Study (Refs. 4, 17, 20, and 21). Based on these references, an estimate of the radio- nuclide concentration in shoreline sediments can be obtained from the following expressions:
C.s Kc Ciw[l
1w - exp(-.it)]
i (A-4)
isc where Cis is the concentration of nuclide i in sediment, in pCi/kg;
CiW is the concentration of nuclide i in water adjacent to the sedinent, in pCi/liter;
Kc is an assumed transfer constant from water to sediment, in liters/kg per day;
t is the length of time the sediment is exposed to the contaminated water, nominally 15 years (approximate midpoint of facility operating life), in hours; and Ai is the decay constant* of nuclide i, in hours-l. In the original evaluation of the equation, Xi was chosen to be the radiological decay constant, but the true value should include an "environmental" removal constant.
The value of Kc was derived for several radionuclides by using data from water and sediment samples collected over a period of several years in the Columbia River between Richiand, Washington, and the river mouth and in Tillamook Bay, Oregon, 75 km south of the river mouth (Refs. 22 and 23). Since the primary use of the equation is to facilitate estimates of the exposure rate from gamma emitters nn*wmeter above the sediment, an effective surface contamina- tion was estimated. This surface contamination was assumed to be contained within the top 2.5 cm (I in.) of sediment.** The dose contribution from the radionuclides at depths below 2.5 cri was ignored. The resulting equation is Si 1 iCi WDl MOT - exp(-Ait)] (A-5) where Si is the "effective" surface contamination, in pCi/m2, that is used in subsequent calculations;
If the presence of a radionuclide in water and sediment is controlled primarily by radioactive equilibrium with its parent nuclide, the water concentration and decay constant of the parent should be used in Equations (A-4) and (A-5). With a mass of 40 kg/m 2 of surface.

Ti is the radiological half-life of nuclide i, in days; and W is a shore-width factor that describes the geometry of the exposure.
Shore-width factors were derived from experimental data (Ref. 24) and are sunanarized in Tdble A-9. They represent the fraction of the dose from an infinite plane source that is estimated for these shoreline situations.
The combination of Equations (A-4) and (A-5) into the general Equation (A-i) leads to
,*uation (A-6) below for calculation of radiation dose from exposure to shoreline sediments.

d. Dose from Foods Grown on Land Irrigated by Contaminated Water The equations in the following paragiaphs can be used to calculate doses from radio- nuclides in irrihjated crops. Separate expressions are presented for tritium because of its unique environmental behavior.
(1) Vegetation The concentration of radioactive material in vegetation results from deposition onto the plant foliage and from uptake from the soil of activity deposited on the ground. The rmodel used for estimating the transfer of radionuclides from irrigation water to crops through water deposited on leaves and uptake from soil was derived for a study of the potential doses to people from a nuclear power complex in the year 2000 (Ref. 4).
The equation for the model (for radionuclides except tritium) is presented below in slightly modified form. The first term in brackets relates to the concentration derived from direct foliar deposition during the growing season. The second term relates to uptake from soil and reflects the long-term deposition during operation of the nuclear facility. Thus for a uniform release rate, the concentration Civ of radionuclide i in the edible portion of crop species v, in units of pCi/kg, is given by:
(A-8 )
iv i" - exp(- '"U t e)]v Biv[I - ex 1(-'P 'itb)1]exp(-..it )
The de;,osition rate, di, from irrigated water is defined by the relation d'i = Ciw (water deposition) (A-9)
I where Ciw is the concentration of radionuclide i in water used for irrigation, in pCi/liter, and I is the irrigation rate, in liters/m2 /hr; i.e., volume of water (liters)
sprinkled on unit area of field in 1 hour.
For tritium, the equation for estimating Civ is (see Ref. 25):
Cv M Ctl (A-10)
For a cow grazing on fresh forage, te in Equation (A--8) is set equal to 720 hours
(30 days), the typical time for a cow to return to a particular portion of the grazing site.

(2) Animal Products The radionuclide concentration in an animal product such as meat or milk is dependent on the amount of contaminated feed or forage eaten by the animal and its intake of contaminated water. The radionuclide concentration in animal products CiA in terms of pCi/liter or pCi/kg (Ref. 4) is proportional to the animal's intake of the radionuclide in feed or forage (subscript F) and in water (subscript w):
CiA = F iAECiFQF + CiAwQAw] (A-li)
The second set of terms in the brackets in Equation (A-1l) can be omitted if the animal does not drink contaminated water. Values for QF and QAw are presented in-Table A-i1.
Values for Biv and FiA are given in Table C-5 (see Appendix C).*

In actual use, it will be necessary to compute separately the milk and meat portions of the dose due to animal products (also applicable to Equation (A-17)).
For tritium, the concentration in animal products is given by the following equation (adapted from Reference 25):
kWCv +QAwCAw (A-14)
CA - +kQCA
m in Since by Equation (A-IO) Cv = Cw, and since for all practical purposes CAw = Cw9 Equation (A-14) can be rearranged as follows:

CA = 3 (w + QAw) (A-15)
in Similarly, the above equations for tritium concentration can be combined with the general Equation (A-1):

MODELS FOR CALCULATING DOSES FROM
NOBLE GASES DISCHARGED TO THE ATMOSPHERE
The following analytical models are used for calculating doses from exposure to gaseous effluents. Separate models are given for air and tissue doses due to gamma and beta rays.
Except for the case of noble gas doses resulting from elevated releases, all models assume submersion in an infinite cloud at the exposure point.
1. Annual Gamma Air Dose from Elevated Releases of Noble Gases Slade (Ref. 1) describes the derivation of the equations for estimating annual air doses from photon emitters dispersed in the atmosphere. The following expression can be used for calculating annual doses:
D 260
n un s I )1 Dik Symbols for this equation were defined earlier, in Regulatory Position C.2.a of this guide.
The photons were combined into energy groups, and each photon intensity within a group was weighted by its energy and energy absorption coefficient. Thus, the effective fraction of disintegrations of the nuclide i yielding photons corresponding to the photon energy group k, Aki, was determined to be Aki I [AmEmpa(Em)]/[Ekwa(Ek)] (B-2)
m where A is the fraction of the disintegrations of nuclide i yielding photons m of energy E
Em is the energy of the mth photon within the kth energy group, in MeV; and Ua (Em) is the energy absorption coefficient in air associated with the photon energy Em, in m All other parameters are as previously defined. The summation is carried out over all photons within energy group k. Data for the photon energies and abundances for most of the noble gas nuclides were taken from Reference 2. For radionuclides not contained in Reference 2, data were obtained from Reference 3.
Decay during travel from the point of release to the receptor is QD = Q* exp(-Xir/un) (B-3)
The term "gamma air dose" refers to the components of the air dose associated with photons emitted during nuclear and atomic transformations, i.e., gamma and x-rays. Annihilation and bremsstrahlung photon radiations are possible contributors to this compunent of the air dose.
Elevated release conditions are assumed to occur when the point of release is higher than twice the height of adjacent solid structures. (See Regulatory Guide 1.111, "Methods for Estimating Atmospheric Transport and Dispersion for Gaseous Effluents in Routine Releases from Light- Water-Cooled Reactors.")
1.109-30
where Qi is the initial release rate of nuclide i, in Ci/yr, and
1 Ai is the decay constant of nuclide i, in sec"
All other parameters are as previously defined.
2. Annual Gamma Air Dose from Ground-Level Releases of Noble Gases and Annual Beta Air Dose Plumes of gaseous effluents are considered semi-infinite in the case of noble gases released from vents. The concentration of the radionuclides in air at the receptor location may be determined from atmospheric dispersion model described in Regulatory Guide 1.111.
The annual average ground-level concentration of gaseous effluent species i at location (r,o) from the release point is determined from xi(ra) = 3.17 x 104 Q*[x//Q' 1D(r,o) (6-4) where xi(r,e) is the annual average ground-level concentration of nuclide i at the distance r in the sector at angle 0 from the release point, in pCi/m 3 , and
[/Q')1D(r,o) is the annual average gaseous dispersion factor (corrected for radioactive decay) in the sector at angle e at the distance r from the release point,.
in sec/mi3 The constant 3.17 x lO4 represents the number of pCi per Ci divided by the number of seconds per year. All other parameters are as previously defined.
The annual gamma or beta air dose associated with the airborne concentration of the effluent species is then I
DY(r,e) or DO(r,e) = xi(re)(OF* or DFO) (B-a)
where the terms are as defined in Regulatory Position C.2.b.
Table B-1 presents a tabulation of the dose factors for the noble gases and daughters of interest.
3. Annual Dose to Tissue from Noble Gas Effluents It is also necessary to determine annual doses to real individuals in unrestricted areas. The staff computes the total body dose from external radiation at a depth of 5 cm into the body and the skin dose at a depth of 7 mg/cm2 of tissue.
a. Elevated Releases The annual total body dose is computed as follows:
DT(r,O) = 1.11 x SF I DI(re)exp[-i (Ek)t] (B-6) Ground-level release conditions are assumed to exist when the release point is less than or equal to twice the height of adjacent solid structures and the vertical exit velocity is less than five times the horizontal wind speed. (See Regulatory Guide 1.111.) The term "beta air dose" refers to the component of the air dose associated with particle emissions during nuclear and atomic transformations, i.e., 0+, B-, and conversion electrons.

Symbols for this equation were defined earlier in Regulatory Position C.2.c of this guide. The constant 1.11 represents the ratio of the energy absorption coefficient for tissue to that for air.
The skin dose has two components, the ganmia and beta contributions. The skin dose rate is computed by DS(r,o) 1.11 x SFD Y(r,o) + 3.17 x 1041 Qi(x/Q']D (r,o)DFSi (8-7)

The skin beta dose factors OFS were determined using the decay scheme source docu- ments cited above and the methods used in References 4, 5, and 6.
b. Ground-Level Releases The annual total body dose is computed as follows:
DT(r,o) = 1.11 x SF ýxi(rO)DFBi (B-8)
Symbols for this equation were defined earlier in Regulatory Position C.2.e of this guide.
The annual skin dose is computed as follows:
Ds(r,o) - 1.11 x SFFZxi(r'e)DFi + xii(ro)DFSi (8-9)
where D5 (r,e) is the annual skin dose due to immersion in a semi-infinite cloud in I1 the sector at angle e, at the distance r from the release point, in mrem/yr, and xi(ra) is the airborne concentration of radionuclide i at point (r,6), in pCi/m 3 .

MODELS FOR CALCULATING DOSES VIA ADDITIONAL PATHWAYS
FROM RADIOIODINES AND OTHER RADIONUCLIDES
DISCHARGED TO THE ATMOSPHERE
I. Annual External Dose from Direct Exposure to Activitv Deposited on the Ground Plane The ground plane concentration of radionuclide i at the location (r,o) with respect to the release point may be determined by

- '-here C . is the ground plane concentration of the radionuclide i in the sector at angle - at the distance r from the release point, in pCi/m2;
Qi is the annual release rate of nuclide i to the atmosphere, J'i/yr;
t is the time period over which the accumulation is evaluated, which is 15 years (riid-point of plant operating life). This is a simplified method of approximating the average deposition over the operating lifetime of the facility;
is the annual average relative deposition of effluent species i at location (r,j), considering depletion of the plume during transport, in mn-2 ; and is the radiological decay constant for nuclide i, in yr-1 .
The annual dose from nuclide i resulting from direct exposure to the contaminated ground plant is then D (r ,) 8760 SFCG(r,r.)DFG (C-2)
where D.j(r,*)
is the annual dose to organ j from the ground plane concentration of nuclide ii i at the location (r,r,), in mrem/yr;
and other terms are as defined previously in Regulatory Position C.3.a of this guide.
The annual dose to organ j is therefore D (r,o) = 8760 S C9(r,o)DFGi (C-3)

2. Annual Dose from Inhalation of Radionuclides in Air The annual average airborne concentration of radionuclide i at the location (r,t!) -ith res- pect to the release point may be determined as Xi(r,o) 3.17 x 104QQ[X/Q'] D(r,) (C-4) where is the release rate of nuclide i to the atmosphere, in Ci/yr;
xi(r,O) is the annual average ground-level concentration of nuclide i in air in the sector at angle 6 at distance r from the, release point, in pCi/m 3 ;
[./Q']D(r,o) is the annual average atmosphere dispersion factor, in sec/m 3 (see Regulatory Guide 1.111). This includes depletion (for radiolodines and particulates)

3. Concentrations of Airborne Radionuclides in Foods The concentration of radioactive material in vegetation results from deposition onto the plant foliage and from uptake of activity initially deposited on the ground. The model used for estimating the transfer of radionuclides from the atmosphere to food products is six:ilar to the model developed for estimating the transfer of radionuclides from irrigation water given in Appendix A of this guide.
For all radioiodines and particulate radionuclides, except tritium and carbon-14, the con- centrition of nuclide i in and on vegetation at the location (r,Q) is estimated using CV(rO) di(r,o) r[l - exp('AEite)] Biv[l - exp(-Ytb)]] exp(-1ith)

Carbon-14 is assumed to be in oxide form (CO and C02 ). The concentration of carbon-14 in vegetation is calculated by assuming that its ratio to the natural carbon in the vegetation is the same as the ratio of carbon-14 to natural carbon in the atmosphere surrounding the vegetation (see Refs. 1 and 2).

This yields CV 4 (ro) = 3.17 x 107 Q74 [x/Q'](r,) 0.11/0.16 U
= 2.2 x 107 Qi4 [x/Q'J(r,O) (C-8)
where Cv 4 (r,O) is the concentration of carbon-14 in vegetation grown at location (r,e), in pCi/kg;
!Q14 is the annual release rate of carbon-14, in Ci/yr;
0.11 is the fraction of total plant mass that is natural carbon, dimensionless;
0.16 is equal to the concentration of natural carbon in the atmosphere, in g/M 3 and
3.17 x 107 is equal to (1.0 x 1012 pCi/Ci)(l.0 x 103 g/kg)/(3.15 x 107 sec/yr).
The concentration of tritium in vegetation is calculated from its concentration in the air surrounding the vegetation. Using the method described in Reference 3, the NRC staff derived the following equation:
CV(r,o) = 3.17 x 107 QT[X/QJ](r,O)(0.75)(0.5/H)
= 1.2 x 10 7 Qi[X/Q'](re)/H (c-9)
where Cv(r,o) is the concentration of tritium in vegetation grown at location (r,e), pCi/kg;
H is the absolute humidity of the atmosphere at location (r,o) in g/m3 Qý is the annual release rate of tritium, Ci/yr;
0.5 is the ratio of tritium concentration in atmospheric water to tritium con--
centration in plant water, dimensionless; and
0.75 is the fraction of total plant mass that is water, dimensionless.
The deposition rate from the plume is defined by:
dC(r.o) = 1.1 x 108ai(r,e)Qj (C-10)
where
6 1 (r,O) is the relative deposition of nuclide i, considering depletion and decay in transit to location (r,O), in m"2 (see Regulatory Guide 1.111) and
1.1 x 108 is the number of pCi per Ci (1012) divided by the number of hours per year
(8760).
For radioiodines the model considers only the elemental fraction of the effluent. The deposition should be computed only for that fraction of the effluent that is estimated to be elemental iodine. Measurements at operating facilities indicate that about half the radioiodine emissions may be considered nonelemental (Reference 4). With this consideration included, Equation (C-l0) for radioiodine becumes:
I

15.5 x Si(r,6)Q.107 (C-1l) and Q! is the total (elemental and nonelemental) radioiodine emission rate. The retention ictor r for elemental radioiodine on vegetation should be taken as unity, since the experimental mea- surement (References 5, 6, and 7) techniques used to evaluate this transfer mechanism consisted of direct comparison of the gross radioiodine concentration on vegetation and the concentration in air (References 8, 9, and 10).
For radioiodines, the deposition model is based only on the dry deposition process. Wlet deposition, including "washout" of the organic and non-organic iodine fractions, should be con- sidered at some sites depending on the meteorological conditions (see Regulatory Guide 1.111).
For particulates, the deposition model considers both wet and dry deposition. There is also a retention factor (r of Equation (C-7)) that accounts for the interception and capture of the deposited activity by the vegetative cover. A value of 0.2 is taken for this factor (References
11 and 12). All nuclides except noble gases, tritium, carbon-14, and the iodines are treated as particulates.
a. Parameters for Calculating Nuclides Concentrations in Veqetation Consumed by Man When the radionuclide concentration in vegetation directly ingested by man is estimated using Equation (C-7), the following parameters are used:

b. Parameters for Calculating Nuclide Concentrations in Milk The radionuclide concentration in milk is dependent on the amount and contamination level of the feed consumed by the animal. The radionuclide concentration in milk is estimated a5 Cm(r,f): FmCiV(r,e)Q exp(-xit) (C-12) where C'(r,a) is the concentration in milk of nuclide i, in pCi/liter;
CY(r,O) is the concentration of radionuclide i in the animal's feed, in pCi/kg;
Fm is the average fraction of the animal's daily intake of radionuclide i which appears in each liter of milk, in days/liter (see Tables C-5 and C-6 for cow and goat data, respectively; for nuclides not listed in Table C-6, use the values in Table C-5);

APPENDIX D
MODELS FOR CALCULATING POPULATION DOSES FROM
NUCLEAR POWER PLANT EFFLUENTS
Calculation of the annual population-integrated total body and thyroid doses should be performed for the three effluent types identified in this guide. These doses should be evaluated for the population within a 50-mile radius of the site, as specified in paragraph D, Section II
of Appendix I to 10 CFR Part 50.
For the purpose of calculating the annual population-integrated dose, the 50-mile region should be divided into a number of subregions consistent with the nature of the region. These subregions may represent, for example, the reaches of a river or land areas over which the appro- priate dispersion factor is averaged. Dispersion factors, population data, and other information describing existing or planned uses of the subregions should be developed.
1. General Expressions for Population Dose For pathways in which the permanent and transient population of the subregion can be con- sidered to be exposed to the average radionuclide concentrations estimated for the subregion, the annual population-integrated dose is calculated as follows:
D Dd0.001 Z Pd Yd jad Djdafda f (D-l)
where Djda is the annual dose to organ j (total body or thyroid) of an average individual of age group a in subregion d, in mrem/yr;
D is the annual population-integrated dose to organ j (total body or thyroid),
i in man-rems or thyroid man-rems;
fda is the fraction of the population in subregion d that is in age group a;
Pd is the population associated with subregion d; and
0.001 is the conversion factor from millirems to rems.
The annual dose to the total body or thyroid of an average individual should be evaluated with the usage factors of Table 0-1. Models and equations for the detailed dose calculations are presented In Appendices A, B, and C of this guide. The annual population-integrated doses from ingestion of potable water, inhalation of airborne effluents, and external exposure to airborne or deposited radionuclides should be evaluated.
For pathways that involve food products produced in the subregion, the food products may be distributed to other areas for consumption. For all the food that is produced within the 50-mile radius, the radioactivity concentrations are averaged over the entire area by weiqhting the concentrations in each subregion by the amount produced in each subregion. This average concentration is used in calculating the population doses. The 50-mile average concentration of nuclide i in food p is computed as C = (/V ) exp(-Ait ) C v (0-2)
ip p 1 p d dip dp The population-integrated dose is the summation of the dose received by all individuals and has units of man-rem when applied to the total body dose and units of man-thyroid-rem when applied to the summation of thyroid dose.

D.Dj is the annual population-integrated in man-rem/yr or thyroid man-rem/yr; dose to organ j (total body or thyroid),
Pp is the population consuming food medium p; and P5 0 is the total population within 50 miles.
All other factors are as defined above.
Note that the above formulation limits the evaluation of the exposed population evaluation to the population residing within 50 miles as specified in paragraph D, Section II of Appendix I to 10 CFR Part 50. In calculating the annual population-integrated total body and thyroid doses, the current age distribution of the population within 50 miles may be assumed to be the same as the current age distribution of the U.S. population (see Reference for Appendix D). Models and equations for the detailed dose calculations are presented in Appendices A, B, and C.
2. Use of the Models a. Population-Integrated Doses from Liquid Effluents The annual total body and thyroid population-integrated doses due to exposure to liq- uid effluents should be evaluated for the following principal pathways: potable water, aquatic food products, external irradiation from shoreline deposits, and terrestrial food products irri- gated with water that has received the liquid effluent. In addition to these pathways, other exposure pathways that arise from unique conditions at a specific site should be evaluated if they provide a significant* contribution to the annual dose received by an exposed population group.
(1) Doses from Potable Water The annual population-integrated total body and thyroid doses from water consump- tion are evaluated for all subregions that have water intakes existing or designated at the time of the license application. The products of the individual doses and the population exposed in each such subregion within 50 miles from the site are summed to obtain the total dose. The formulation expressed in Equation (D-1) may be used.
The total body and thyroid dose of the individuals should be evaluated using Ecuation (A-2) in Appendix A of this guide, together with the age-dependent usage factors Uap obtained from Table D-1. The dilution from the discharge point to the usage point should be evaluated using appropriate hydrological models for the various subregions.
If the population served by a particular water supply system is not known, it can be estimated by the following:
Pw = v/c (D-5)
where c is the average daily usage of individuals on the system, in gal/day per person;
Pw is the estimated population served by the water system; and v is the average'daily intake of the water supply system, in gal/day.
If the industrial usage from the water supply system is known, it can be sub- tracted from the average daily intake of the system before this value is entered into Equation (0-5).
For the purpose of this guide, any additional pathway is deemed to be significant if a conservative evaluation of the pathway yields an additional dose contribution equal to or greater than 10% of the total from all the pathways described here. Any pathway so identified should then be evaluated by a model similar to that used above.
1.109-67
The population served by a water supply system whose intake is within the 50-mile radius may include individuals who reside outside the circle. This population may be pro-rated to include only the population within the 50-mile radius. Conversely, a water supply system with an intake beyond the 50-mile radius may serve the population within the 50-mile radius.
Such exposed population should be included in the 50-mile population dose evaluation.
(2) Doses from Food Products The annual population-integrated total body and thyroid doses from consumption of aquatic food products are evaluated using the production of sport and commercial harvests in the various subregions. The mixing ratio (or dilution) should be evaluated for each sub- region using an appropriate hydrological model. For sport harvests, the entire edible harvest is assumed to be ingested by the population within 50 miles. The formulation expressed by Equation (D-4) should be used with the population Pp given by the results of Equation (D-3). The age-specific ingestion factors of Table D-I may be used in lieu of site-specific data.
For commercial harvests, the production within 50 miles from the site is con- sidered as part of the total U.S. harvest. Equation (D-2) should be used to compute the average concentration, with Vp as the total estimated U.S. commercial harvest of the aquatic food medium p. The annual population-integrated dose is then computed using Equation (D-4) with Pp = PSO" The age-specific factors of Table 0-1 may be used in lieu of site-specific data.
(3) Doses from Shoreline Deposits The annual population-integrated total body and thyroid doses from recreational activities on the shoreline of the receiving water body are evaluated by sunmming the product of the individual doses in each subregion and the population exposed therein. All subregions within the 50-mile radius should be considered where existing or designated recreational facili- ties exist. If available, actual recreational usage in the vicinity of each facility should be used. The formulation of Equation (D-1) is appropriate.
(4) Doses from Consumption of Terrestrial Food Products Irrigated by Waters Receiving the Liquid Effluent The annual population-integrated total body and thyroid doses from consumption of food irrigated with water from the body receiving the liquid effluent are evaluated following the procedures outlined in the development of Equation (0-4). Note that the term Vp of Equations (0-2) and (D-3) denotes the total production of food medium p within 50 miles, not just the total production of irrigated food medium p. The consumption rate data of Table D-1 may be used in lieu of site-specific data in the evaluation of Equation (D-4).
b. Population-Integrated Doses from Airborne Effluents The annual total body and thyroid population-integrated doses should be evaluated for the following principal exposure pathways: noble gas submersion, inhalation of airborne efflu- ents, ingestion of contaminated terrestrial foods (milk, meat, and vegetation), and external irradiation from activity deposited on the ground. In addition to these pathways, other exposure pathways that arise from unique conditions at a specific site should be evaluated if they provide a significant contribution to the annual dose received by an exposed population group. (See Regulatory Position C.1 of this guide.)
For the evaluation of exposures from atmospheric releases, the 50-mile region should be divided into 160 subregions formed by sectors centered on the 16 compass points (N, NNE, NE, etc.)
and annuli at distances of 1, 2, 3, 4, 5, 10, 20, 30, 40, and 50 miles from the center of the facility. The atmospheric dispersion factors (x/Q') or similar factors should be evaluated at the radial midpoint for each of the subregions using appropriate atmospheric dispersion models such as those described in Regulatory Guide 1.111.
(1) Doses due to Exposure to Noble Gases The annual population-integrated total body dose due to noble gas effluents should be evaluated by summing the products of the individual doses in each subregion and the population in each subregion. Equation (D-1) may be used. For external exposure, the model does E not differentiate between age groups. A structural shielding factor of 0.5,should be applied in conjunction with the dose factor data of Table B-1.

(2) Doses due to Inhalation of Radlolodines and Particulates The annual population-integrated total body and thyroid doses from inhalation of airborne effluents should be evaluated by summing the products of the individual doses received in each subregion and the population in each subregion. Equation (D-1) may be used.
The age-specific inhalation rates of Table D-1 may be used with the data of Tables C-l to C-4.
(3) Doses due to Ingestion of Terrestrial Food Products The annual population-integrated total body and thyroid doses from ingestion of terrestrial food products should be evaluated using the production data for each subregion.
For milk, meat, and commercial vegetables, the formulation of Equation (0-2) should be used to calculate the average concentrations in the foods. These concentrations are then used in Equation (D-4), along with the data of Tables D-1, D-2, and A-l to calculate population doses.
(4) Doses due to External Irradiation from Activity Deposited o' the Ground The annual population-integrated total body and thyroid doses from external exposure to surface deposition of the effluent should be evaluated using Equation (D-l). A household shielding and occupancy factor of 0.5 should be applied in conjunction with the dose factors of Tables A-3 to A-7.
