Measurements made are divided into four categories or pathways based upon how the results may affect the public. Airborne, waterbome, ingestion and direct radiation are the four pathways that are sampled. Each pathway is described below. THE FOUR MEASUREMENT CATEGORIES airbornepathway , . f i i- }

The South Texas Project continues to operate with no negative effect on the population or the o environment. The exposure for people living in the area is maintained at less than one millirem per year. Environmental programs at the site monitor known and predictable relationships between the operation of the South Texas Project and the surrounding area. These monitoring programs verify that the operation of the South Texas Project has no detectable impact offsite and is well within state and federal regulations and guidelines. These programs are verified by the state of Texas - through collection and analysis of samples and placement of the state's thermoluminescent dosim-eters. . G

Table 3: 1998 Radiological Environmental Monitoring Program Analysis Summary I An analysis summary for all of the required samples is given in Table 3. The table has been formatted to resemble a United States Nuclear Regulatory Commission industry standard. Modifications have been made for the sole purpose of reading ease. Negative values are re-poned in this table. Reported negative values are required to do long term studies where the true values are near zero or when there exists a negative bias in the measurement. Media type is printed at the top left of each page, and the units of measurement are printed at the top right. The first column lists the activity or specific radionuclide for which each sample was analyzed. Total analyses perfonned for the " indicated nuclide/ the total number of nonroutine samples analyzed"is given in the second column. (A nonroutine measurement is a sample indicating a value greater than the reporting levels for Radioactivity Concentrations in Environ-mental Samples.) The " LOWER LIMIT OF DETECTION" column lists required values. Not all of the listed analyses or radionuclides have required lower limits of detection. Typically, the values achieved are significantly lower than the required. A set of statistical parameters are listed for each radionuclide in the remaining columns. The parameters contain infonnation from the indicator locations, the location having the highest annual mean, and information from the control stations. Some sample types do not have control stations. When this is the case,"no samples"is listed in the control location column. For each of these groups of data, the following is calculated:
+ The mean value (including negative values and values below the lower limit of detection).
+ The number of analyses whose values were greater than the lower limit of detection / the total number of analyses.
+ The lowest and highest values for the analysis.
The data placed in the table was changed in 1995 from the previous reports to only include the data from the samples listed in Table 1. Additional thennoluminescent dosimetry is utilized each quarter for quality control purposes. The number of analyses will be the same as required with 6-23 the addition of seven surface water samples, two groundwater samples, two drinking water samples, two shoreline sediment samples and three bottom sediment samples. Vegetation samples vary in number according to availability. TABLE 3 1998 RADIOLOGICAL ENVIRONh1 ENTAL 510NITORING PROGRAh!
