SUMMARY
During this operating period tor Calvert Cliffs Nuclear Power Plant Units 1 anc 2. Baltimore Gas ano Electric Comoany tBG&E) ano Teledvne Isotooes analvzed samoles trom the aouatic. atmosoneric. anc terrestrial environments. A total at 1.112 analyses were certormed on 750 environmental samoles auring this ceriod. In accition. BG&E cersonnel analyzed ble tnermoluminescent costmeters t TLD'si tor amotent ractation cose rates.
Samoles trom the aouatic environment incluced bav water, fish, snelltish tovsters and craos). ano seciment. Bav water was analvrea tor tritium.
Sr-89. Sr-90, ano gamma emitting nuclides. Fish, sne11tish. and sealment were analyzeo for gamma emitting nuclices. Fisn cones and sediment were also analyzed tor Sr-89 and Sr-90.
Monitoring ot the atmosoneric environment inclucea samoling air ano crectoltation. Air oarticulates anc gaseous socine were collected on glass fiber tilters ano silver zeoitte molecular sieve cartricges, resoectivelv.
Tne carticulate t11ters were analv:ec tor gross ceta activity ano for gamma emitting nucisces, wn11e the molecular sieve cartriages were analvzed
.- +or 1-131. Hnaivses were made tor Sr-89 anc Sr-90 on cuarteriv
? comcosited air oarticulate eliters. Preclottation was analvred tor gross oeta. M-5. Sr-89. Sr-90, and gamma emitting nuclides.
Samoles trom tne terrestrial environment incluced milk. vegetation, soll.
ano ground water samoles. Milk samoles were analvted for gamma emitters.
1-131. Sr-89. and Sr-90. The vegetation and t.911 samoles were analv:ed
. tor gamma emitters. Sr-89. and Sr-90. The cround water samoies were analvted tor H-3 and gamma emitters.
Measurements at external radiation were certormeo ov analv ing TLD's trom 13' locations surrounding the olant.
Low levels of various racionuclides were coserved in the environs of the olant during 1984. Some at tnese observations are attributable to tallout from cast atmosoneric nuclear testing, ano some are related to the coeration of tne olant. With reference to tne latter ooservations: H-3 was coservea in two cav water samoles trom locations 7 and 8: Ag-110m was coservea in all ovster samoles from location 5: Co-58 ana Zn-e5 were also coservec in ovsters ta single samole trom location 5is Co-ed acoearea in seciment samoles in a cattern similar to tnat coserved in tne oast and Co-58 was observea in a single soll samole trom location 11.
In orcer to assess tne olant s contrioution to tne amotent raatation
- levels at the surrounalno environment. cose calculations were certormea j using the olant s ettluent release cata. on site meteorological cata. and
! accroortate oathwavs. The results et these cose calculations indicates e

The analvtical results for tnis reoorting period. oresented in Appendix B and also summarized on an annual basis in Table 2. have been divided into four categories - aquatic envaronment. atmospheric environment. terrestrial environment. and external radiation. ,
D.1 Acuatic Environment The mouatic environment surrouncing tne plant was monitored by analvzing samoles at Day water. aquatic organisms. and octrom sediment. These samoles were octained trom various sampling locations on the Chesaceake ,
Bay near the olant. i D.I.a Bav Water Montniv bay water samoles were taken from two locations the Plant Intake area slocation 8). ano tne Plant Outtall area (location 7). These samoles were analyzed for H-3. gamma emitters, and Sr-89 and Sr-90.
Monthly analyses tor M-5 showed detectable concentrations in oniv two of -t tne samoles collecteo. Inese detectable concentrations were 291+/-125
-- oC1/1 ooservec in the Hugust sample trom location 7 and 146+/-126 oC1/1 in tne Decemoer samole from location B. sotn concentrations are similar to tne results ooserved in Doth the orecoerational tes and previous coerational oorloos (7.20).
Montniv analyses for gamma emitters exhibited no oetectacle concentrations i ot any tission or activation products in these samoles.
Quarterly analyses for radiostrontium exhibitea no detectacle concentrations of these nuclides in any of the composited samoles.
D.I.o Acuatic Organisms i

Quarter 1v analyses for gamma -ematters in she11ttsn samoles exntbited detectable concentrat1ons ' ot radionuclides in oniv the oyster samoles obtained from location ' b. S11ver-110m. rangang from 77+/-10 to 194+/-16 oC1/kg, was oeserved in all the ' oyster samoles taken trom th1s location. -
In addit 1on to tne Ag-110, ostectacle concentrations of the activation oroducts Co-58 (23+/-8 pCi/kg; and Zn-65 (25+/-17 : oCi/kg) were also observeos nowever, they were only observec In the June oyster samole from th1s location. The concentration levels of these nuclides are similar to the levels ooserved in orevious years (15-20). and their presence is plant-related.
Quarteriv radiostrontzum analyses of the pones of tish samoles snowed no measureacle concentrations et Sr-89. Strontium-90 on the other hana was ooserved in most samoles in ene range at 2.4 +/ -1.6 to 3.4+/-1.0 pC1/kg.
These results are similar to the general patterns ooserved in both the oreocerational tes and orevious operational persons (7.20)
D.1.c sootment Quarteriv seciment samoles were taken trom tour locations: Camo Conov
- tiocation 5). Long Beach tiocation 6i. Plant intake area tiocation 87. and
- Plant Outta11 area tiocation 7). These samoles were analvrea tor gamma
. emitters and Sr-09 and Sr-90.
Quarteriv analvses for gamma emitters in these samoles revealso the oremence et Cs-137. ranging trom 130+/-51 to 1282 +/-156 oC1/ kg in all
- samoles from all locations. anc Co-ad, ranging trom lev +/-92 to 527+/-128 oC1/kg in most of tne samoles trom all locations. The range at Cs-137 concentrations exntbited are similar to the ranges ooserveo in tne orecoerational (es and ortor coerational oorloos (7.20) and is pronaoiv related to cast atmosoneric nuclear weapons testing. On the other nand.
Co-e8 1s among tne activation ano tission bv-oroducts releaseo trom tne olant in routine ractoactive discnarges. Its range et concentrations is similar to those coserved in orevious coerational pertoos (7.20).
Quarteriv ractostrontium analyses of tne sediment samples exnibited no i measurmable concentrations et either Sr-bY or Sr-90.

Weekiv analvses tor oeta activity on air particulate tilters revealed that tne annual range at cata tor eacn location is very similar to tne annual ranges exhibited in 1983 (20) and is, once again, mucn lower than the annual ranges exnibited in orevious vaars t13-19). This is most prooably due to a graoual oecrease of atmosoneric tallout trom cast nuclear weaoons testing. This vear's ranges and last vear s ranges are similar to tnose observed orlor to Sootember. 1976 wnen tne Peooles Reouclic of China detonated the tirst of a series of nuclear weaoons (12).
Monthly analyses fcr gamma emitters snowed no measureanie concentrations at any tission or activation Dv-procucts in these samoles.

D3 Terrestrial Environment The terrestrial environment was monitored ov analyzing samoles of milk.
vegetation, soll. ano well water. These samoles were collected trom various samoling locations near the plant.
D.3.a Milk Milk samoles were collected montniv wnen availaole from two locations: a nearov tarm tM1111ngs Farms ano a local store in the town of S t. Leonarc tlocation 30). Tnese samoles were analv:eo for 1-131. gamma emitters, and Sr-8Y and Sr-90.
Analvses tor 1-131 in these samoles showed no cetectacle concentrations o+ tnis racionucitae in anv ot tne samoles trem either location. Tvolcal MDL's were in the range at 0.1 to 0.3 oC1/1.
Analyses tor gamma emitters in these samoles snowed cetectacle concentrations at Cs-137 in three at tne milk samoles collectea trom the M1111ngs Farm. ranging trom 8+/-/ to 12+/-o 0C1/l. This racionuclice nas atten Deen ooservec in vegetation samoles collectec trom tne surrouncing
- farms and nas oeen attricutec to cast nuclear weaoons testing t7-20).
Tne cresence et tnis racionuclice in these milk samoles is orceab1v cue to the cow s ingestion at vegetation samoles similartiv contaminated witn tallout from tnese cast weaoons testing.
Radiostrontium analyses 0+ tne milk samoles exntottec no cetectacle cresence of Sr-89 in any ot the samoles. The analyses did reveal the cresence ot $r-90 in all of the milk samoles trom cotn locations, ranging trom 1.0+/-0.5 to le+/-1 0C1/1. The cresence et Sr-90 is most orobably due to tallout from cast nuclear weaoons testing.
D.3.b Vegetation i
Vegetation samoles were collected trom tnree locations: On Site (location 14)r a nearov tarm ilocation 15s. ano anotner nearov tarm intilings Farmi.

On the otner hand. the analyses revealed the oresence et Sr-90 in most of the vegetation samoles, ranging trom 6 to 78W oG1/kg. Ihts range of Sr-90 results indicate tne same general patterns ooservec in orevious years t7-20) ano is most procaoly attributable to fallout trom cast weaoons testing.
D.3.c Soil Soil samoles were taken tros tnree On Site locations: 11, 12. ano 13.
These samoles were analyzed tor gamma emitters and Sr-89 and Sr-90.
Analyses for gamma emitters revealed tne presence at Cs-137 in most of these samoles, ranging trom 226+/-70 to 554+/-96 oC1/kg. In addition.
Co-58 was coserved in tne Sootemoer' soll samole trom location 11 at a concentration et 190+/-55 oC1/ kg. The Cs-137 results are similar to those observed in tne oreocerational te) and orevious operational oorloos (7.20) ano are procaolv aue to tne oeoosition of tallout trom past nuclear weaoons testing. The Co-$8. on tne other nand is orocaolv related to olant operation.
. Radiostrontium analyses of the soll samples showed no detectacle concentrations of Sr-89. and oniv two cetectacle concentrations of Sr-90 in tne Feoruarv samoles trom locations 11 ano 13 114+/-a and 15+/-3 oC1/kg

The current means anc ranges expressac in Taole 2 were comoarea with the means and ranges for the scan of years trom.19 78 to 1983 (15-20). This comoarsson revealea that the means and rances tor 1984 were similar to those coserved in the tive orececing years.
E. CONCLUSION Low levels at various racionuclides were caserved in the environment surrouncing the olant during 1984. Most o+ these coservations were attributeo to the fallout trom atmosoneric nuclear weapons testing, and others were related to tne operation ot the olant (viz.. H-3 in bay water 1 Co-58, Zn-45 and Aq-110m in snelittsn samoles: Co-se in sociment samoless and Co-58 in soil samoless.
In order to assess the olant's contribution to the amotent radiation levels at tne surrouncing environment. cose calculations were certormeo using tne olant's ettluent release cata. on site meteorological data. and accroortate cannways. The results at tnese dose calculations indicates
- a. a maximum tnvrold dose (via innalation and garden vegetaole cathwaysi ot 0.07 mrem at location 14 whten is 0.l*/. of the acceotaole limit of 75 mrem /vear as specified in 40 CFR 190 invironmental Ractation Protection btandards for Nuclear Power Operations, and a maximum tnvroic cose (via milk oathway) of 0.71 mrem at Millings tarm. wnten is less tnan 1.0% of the acceotaole limit at 75 mrem /vear (40 CFR 190):
