RADIOLOGICAL ENVIRONMENTAL SURVEYJanuary-December1994SUMMARYDuring1994,therewerenomeasurable influences fromradioactive effluentreleases.

Routinemeasurements continually aretakenintheareassurrounding theR.E.GinnaNuclearPowerPlanttodetermine ifman-maderadioactivity isreleasedatalevelthatwouldcauseaninfluence totheenvironssurrounding theplant.Thesemeasurements detectednomeasurable activityaboveestablished background levels.Samplesarecollected onanestablished scheduleforregulartestingtodetermine ifmeasurable levelsofactivityexistthatmaybeattributed totheoperation oftheplant.Theinformation obtainedfrommeasurements oftheseenvironmental samplesiscomparedtothecalculated levelsofpotential activityatthesamplinglocations fromnormalplantreleasesasdetermined bymonitorswithintheplanteffluentstreams.Samplesofwater,air,fallout,fish,vegetation, milkanddirectradiation arecollected fromlocations neartheplantthatweredetermined tobeatthepointofhighestconcentration fromreleasesthroughtheplantandcontainment vents.Samplesarealsocollected fromadditional locations atdistances rangingouttoeighteenmiles.Reference samplesforbackground measurements arecollected concurrently fromlocations calculated tohaveradioactivity concentrations lessthan1%ofthosefromtheclosersamplinglocations.

Thesebackground samplesprovidecontinuous background datawhichmakesitpossibletodistinguish betweensignificant radioactivity introduced intotheenvironment fromtheoperation oftheplantandthatintroduced fromothersources.During1994,1471sampleswerecollected for1900analysesforbetaandgammaemittersthroughgrossactivitycountingtechniques andgammaspectroscopy.

Thesetotal931airsamples,298watersamples,21fishsamples,8vegetation samples,57milksamples,2speciallakesamplesand154thermoluminescent dosimeter measurements.
