Unit #1 became critical on December 11, 1976, thereby initiating the operational phase of the Radiological Environmental Monitoring Program (REMP).

This program was designed to identify and ciuantify concentrations of radioactivity in various environmental media and to quantify ambient

• radiation levels in the environs of Artificial Island. During the operational phase, the program \\iill monitor the operations of SNGS Unit #1, fulfill the requirements of the SNGS Environmental Technical Specifications, and provide background data for SNGS Unit #2 and.

INTRODUCTION  !

Radiation Managemen't Corporation (RMC) has participated iii the Artificial Island Radiological Environmental Monitoring Program (REMP) since January 1973.

• RMC has previously reported results from the preoperationa 1 phase of the REMP for 1973(1), 1974(2), and 1975(3). On December 11, 1976, SHGS Unit #1 became critical, thereby initiating the operational phase of the REl*1P. RMC has also reported results from the initial operating period between December 11 a11d December 31, 1976 (5). This rerort summarizes the operational period betv1een January 1 and December 31, 1977. Interpretatfon of the data and conclusions

• are also presented.

Artificial Island will eventually be the site of four nuclear power reactors.

Two of the reactors will be part of the Salem Nuclear Generating Station.

Unit Ill is a 1090 Mi.Je pressurized \\later reactor (P\ ./R), and is presently 1

operational. Unit #2, now under construction, will consist of an 1115 MWe

• PvJR and is scheduled for operation inl979. The remaining two units \vill be part of the Hope Creek Generating Station.

Artificial Island is actually a man-made peninsula in the Delaware River, created by the deposition of dredging spoils. It is located in Lower Alloways

• Tovmship, Salem County, Ne1*J Jersey. The env*ironment around Artificial Island is characterized mainly by the Delaware River and Bay, extensive tidal marshes, and grass lands. These land types n:ake up approximately 85% of the land area within five miles of the site. Most of the remaining land is used for agricultural production. (6)

• More specific information on the demography, hydrology, meteorology, and 1and use characteristics of the local area may be found in the Environmental Report (6), Environmental Statement (7), and the Final Safety Analyses Report (Units 1 and 2) for SNGS (8).

• THE PROGRAM I In the operational phase of the REMP, tile prooram was conducted in accordance with section 3.2 of the SNGS Environmental Techrrical Specifications. Radio-

• analytical data were collected for comparison with results from the preoperational phase. Differences between these periods were examined statistically to determine whether any station effects exist. These observations were based on the magnitude and fluctuations of radioactivity levels determined in the preoperational phase.

• Objectives The objectives of the operational radiological environmental program are;

1. To fulfill the obligations of the Radiological Surveillance-Environnental sections of the En vi ronmenta 1 Techni ca 1 SpeciJi ca ti ans for SliGS .

• 2. To determine whether any significant increase occurs in the conceHtration of radionuclides i11 critical pathways.

3. To determine if St*lGS has caused an increase in the radioactive inventory

• • of long lived radionuclides .

4. To detect any change in ambient gamma radiation ievels.

5. To verify that SNGS operations have no detrimental effects on the health and safety of the pub 1i c or on the environment.

This report as required by section 5.6 of the Salem ETS summarizes the findings of the 1977 REMP. Results of the four year preoperational program have been summarized in reference 4 for purposes of comparison with subsequent operationa 1 reports.

Sample Collection In order to meet the stated objectives, an appropriate operational REl*1P v1as developed by RMC.in cooperation with Public Service Electric and Gas Company.

The operational REMP includes samples from the aquatic, atmospheric, and

• terrestrial environments, as well as TLDs to measure ambient radiation.

Samples of various media were selected to obtain data for the evaluation of the radiation dose to man and other organisms. *Sample types were based on=

(1) established critical pathways for the transfer of radionuclides through the environment to man, and (2) experience gained during the preoperational phase. Sampling locations were determined from site meteorology, Delaware

• • estuarian hydrology, local demography, and land u~es.

Sampling locu.tions were divided into two classes--indicator and control.

In di ca tor stations are those which u.re expected to manifest station effects, if any exist; control samples are collected at locations v1hich are believed

• 3

• to be unaffected by 1station operations. Fluctuations in the levels of radionuclides and d~rect radiation at indicator stations are evaluated with respect to analogous fluctuations at control stations, \*1hich are unrelated to station operation. Indicator and background station data are also evaluated relative to preoperational data. The REMP for the Artificial Island site

• includes additional samples ~nd analyses not specifically required by the Salem ETS. The summary tables in this report include these additional samples an.d analyses.

All samples from the aciuatic environment were collected by Ichthyological

• Associates and shipped ~o RMC for analysis. Surface water samples were collected in nevi polyethylene bottles. Sample containers \*/ere rinsed t1-1ice with the sample medium prior to collection. Edible and prey fish were taken by net,-sealed in a bag or jar and shipped frozen. Blue hardshell crabs were taken with wire crab traps, sealed in plastic jars and shipped fresh.

Benthos and sediment were taken with a bottom grab sampler.

The atmospheric environment was examined by analyzing air particulate filters, iodine charcoal cartridges, and precipitation. Air particulates were collected on Hollingsworth and Vose H-70-018 filters with low-volume air samplers (1 cfm).

Iodine was collected from air by adsorption on TEDA charcoal cartridges connected in series behind the air particulate filters. Air sample volumes

• ~1ere measured vii th calibrated ~fry-gas meters corrected to standard tempetaturc and pressure. Precipitation was collected on a 95-square-inch rain gauge.

Samples were collected monthly and transferred to new polyethylene bottles.

The rain gauge was rinsed at collection with distilled water to include residual particulates in the precipitation samples. Results of subsequent analyses were corrected for the increase in volume. Tritium results were also corrected for the tritium content of the distilled water.

The terrestrial environnient was examined by analyzing samples of well water, potable water, milk, beef> food products~ fodder crops, bovine thyroid, and soil.

Monthly well and potable water samples were taken in new t\'/o-gallon polyethylene bottles. Separate raw and treated potable *1-1ater samples Here composited daily by personnel of the Salem Water Company. The Salem ;./ater Company draws its water from Laurel Lake and adjacent wells, which are not .

expected to be influenced by SNGS liquid discharge. Milk samples were taken in new polyethylene bottles and shipped fresh. Food products, fodder crops, game, bovine thyroid, and soil samples were taken and sealed in plastic bags or jars. Perishable samples were frozen at the time of sampling without any prevervatives.

Ambient radiation levels in the environs were measured with energy-compensated CaSOlf(Tm) thermoluminescent dosimeters (TLDs). Packets containing four TLDs each were placed on and around the Artificial Island site at various distances

.* and were exposed on a monthly and quarterly basis.

. Appendix A describes and summarizes) in the format of table 5.6-1 of the Salem ETS, the entire operational program as performed in 1977. Appendix B describes the RMC coding system, which specifies sample type and relative locations at a glance .. Also in appendix B, Table B-1 gives the pertinent

• information on individual sampling locations, \*1hile maps B-1 and a..:.2 shol'. the sampling locations.

Data Interpretation!

Radiation Management Corporation has an extensive quality assurance program designed to maximize confidence in the analytical procedures used. The analytical methods and quality control procedures utilized in this program are described in an RMC publ.ication (9). Approximately 20% of the total analytical effort is spent on quality control, including process ciuality control, instrument quality control, inter-laboratory cross-check analyses, and comprehensive data review. The analytical data generated during the

• program also are routinely evaluated by the RMC project leader 1vho is tile liaison \vi th Public Sei~vi ce Electric and Gas Company personnel . Several factors are important in the interpretation of the data. These factors are discussed here to avoid-repetition in sections that follO\\I, Grab Sampling is a useful and acceptable procedure for taking environment~l samples of a m2dium in v1hich the concentration of radionuclides is expected to vary slowly v1ith time .or where intermittent sampling is deemed sufficient to establish the radiological characteristics of the medium .. This ..method, however, is only representative of the sampled medium for ihat specific**.

location and instant of time. As a resulti variation in the radionuclide*

concentrations of the samples ~*1ill normally occur. Since these variations

• • will tend to counterbalance one another, the ~xtraction of averages based upon repetitive grab samples is valid.

It is *characteristic of environmental monitoring data that many results occur at or below the minimum detectable level (MDL), as defined in reference 9.

For reporting and calculation of averages, any result occurring at or belo1*1 the minimum detectable level is considered to be at that level. Averages obtained using this method are therefore biased high.

Within the data tables (appendix C) an approximate 95% (+/-2 sigma). confidence interval is supplied for those data points above the minimum detectable level.

These intervals represent the range of .values into which 95% of repeated

• analyses of the same sample wou1d fa11.

Results for each type of sample were grouped according to the analysis performed .. Means and standard deviations of these results were calculated when applicable. The calculated standard deviations of grouped data found

• in appendix C represent sample and not analytical variability. When a group of data was composed of mainly (>50%) MDL values, averages were not calculated.

• RESULTS AND DISCUSSION I

The analytical results of the 1977 REMP samples are typically divided into four categories: Atj~atic) Atmospheric, Terrestrial, and Direct Radiation.

The individual samples and analyses 1-1ithin each category display the unique

• radiological characteristics- of that type of environment. The analytical results for the 1977 REMP sampl~s are summarized in appendix A. The data for individual samples are presented in appendix C.

A census of milk-producing animals \vas conducted tvlice during 1977 as part of the REMP. These censuses indicatr.d no ne1v du.iry operations within 5 miles

• of Sl~GS. They ulso indicated some slight fluctuations in the numbe1~ of co1*1s on individual farms and that one farm ceased dairy operations.

Agua tic Environment

• The aquatic environs of Artificial Island comprise a portion of the Delaware River-Bay estuary. Usage by man and the physical characteristics of this system have been described by Thomann (10). Ichthyological Associatc~s is making continual ecological studies (11) of the estuary in the vicinity of Artificial Island. This information has been used in evaluating the aciuat-ic portions of the REMP. The radiological characteristics of the aquatic environs

• of Artificial Island \*.Jere stud.ied by analyzino samrles of surface water) edible fish, blue crabs, prey fish, benthos and sediment.

Surface \~ater Monthly surface v1ater samples were taken at five locations in the Delm*1are

-* estuary. One is dOl*mstream from the outfall area, one is in the outfall area, and another is directly v1est of the outfall area at tl1e mouth of the Appoqui nimi nk River'. Two other stations are 1ocated upstream--one station is in the river and the other is in the.Chesaneake and Delaware Canal.

The station located at the mouth of the Appoquinimink River serves as the operational control. Surface water samples v1ere analyzed for tritiulil,

-* alpha emitters, beta emitters, strontium-89 and-90, and gamma emitters.

Analysis of surface water for H-3 yielded an average concentration of 177 pCi/l and ranged from <80 to 460 pCi/l. These levels are similar to those measured in the preoperational program as shown in figure 1.

-* Gross alpha concentrations were generally below MDL, which ranged from 1.5 to 33 pCi/l. Only 2 of the 55 samples analyzed .showed detectable gross alpha activity. Those results (2 and 14 pCi/l) were within the same range as the MDLs. Alpha activity may be expected in suspended solids from naturally occurring radi onucl ides especially during peri ads of high surface runoff.

-* Gross beta concentrations ranged from 4.3 to 140 .pCi/1 and averaged 43 pCi/l.

Nearly all of the beta activity was contributed by K-40 (<7 to 170 pCi/l),

a natural component of salt and brackish waters, as illustrated in figure 2, comparing gross beta and K-40 concentrations in the Delaware River. Due to the flO\*/ rate variu.tions and the tidal nature of the estuarine enviornmcnt,

• large variations in the gross beta concentration were observed* thr.ougl1out the year. Much of this variation can be attributed to the tidal stage at the time of sampling .

Gamrn:J. spcctrornetr1c 1 analysis of surface v1ater samrles shmved detectable concentrations of K~~o in 49 of 55 samrles. The average K-40 concentration was 36 rCi/l and rariged from <7 to 170 pCi/l. T1vo additional gamma-emitting nuclides, Cs-134 and Cs-137, with concentrations of 0.3 pCi/l and 1.2 pCi/l e respectively, were* -observed Jn the February sample from contra l l oca ti on lGFl.

Ces i um-137, 1*1h i ch has randomly occurred throughout the preopera tiona l period, is associated with fallout from past nu cl ear weapons testing and can be expected to occur periodically in the future .

• The Cs-134 result of 0.8+/-0.6 pCi/l is comparable to the minimum detectable level of 0.5 pCi/l for the other samples. In addition) the su.rnple v1as taken 6.9 miles upstream of the site; and since the SfJGS did not release any cesium during February 1977 it can be concluded that the observed Cs-134 was not plant related. (12) *

• Levels of Sr-89 were below MDL (0.6 to 1.2 pCi/l) in all samples. Levels of detectable Sr-90 ranged from 0.3 to 0.5 11Ci/l in 7 of the 20 samples. The MDLs values ranged from 0.4 to 0.9 pCi/l. The maximum level of Sr-90 detected in the preoperational program was 1.6 pCi/l .

Aquatic Organisms Biological samples from various levels of the human food chain were taken from the same stations as surface water samnles. These included edible fish, blue crabs, prey fish, and benthic organism~~

e Edible fish samples (American Shad, alewife, etc.) were collected at three locations and analyzed for gamna emitters and tritium. Fish bones 1*1ere analyzed for Sr-89 and Sr-90.

Gamna spectrometry of these samples showed only K-40 at detectable levels.

This nuclide was detected in all fish flesh samples at an average concentration of 3800 pCi/kg-wet, 1*1hich is typic:al for this naturally occurring nucljde.

Tri ti urn analyses were performed on both aqueous and organic fractions of the flesh portions of these samples. The average concentration of tritium \'/ils 131 pCi/l for the aqueous fraction and 214 pCi/l for the organic fraction.

The observed results are essentially the same as those found in surface water for the same period, indicating no biological accumulation of tritium.

. . - --*~'.:.... ~~

All the bone samples analyzed fdr Sf~9 \*Jere below minimum*detectable level (1.7 to .8.8 pCi/g-dry), l'lith one exception. The June sample from station llAl had a detectable level of 0.1 pCi/g-dry, which is belO\*/ the MDL of all the other samples. One of the four samples analyzed for Sr-90 had a detectable*

concentration of 0.09 pCi/g-dry. This concentrafion is below the MDL range (0.4 to 1.6 pCi/g-dry) of the other analyses and is similar to the other values.

B1ue ha rdshe 11 crabs were taken at t\'/o 1ocations with the edi b1e port ions being analyzed for gamma emitters, tritium and Sr-89 and-90. The _shells were also analyzed for Sr-89 and-90.

Gamna spectrometry of the edible *portions sh01*1ed K-40 conce1itrations in all samples ranoing behyeen 2200 and 3300 pCi/kg-1-vct, with the average being 2800 pCi/kg-wet. One sa1Dple taken at control station 12Cl had a trace amount of Cs-137 (18 pCi/kg-wet).

Tritium analyses performed on the edible portions showed an average concentration of 206 pCi/.l. *No significant differences in H-3 levels were observed between samples, reflecting an equilibrium beb1een the blue crabs and their estuarine environment.

• Radiostrontium analyses on the flesh portions of the samples indicated no detectable concentru.tions of Sr-39, v1ith the MDL ranging betl'/C~en 0.03 and 0.04 pCi/g-wet. Detectable concentrations of Sr-90 (0.006 pCi/g-wet) were observed in the August sarnrle collected at both locations. This activity 1*~as similar to the Sr-90 MDL of the June samples, v1hich were 0.007 and O. 008 pCi I g-wet .

• • The blue crab shell samples analyzed for Sr-89 showed detectable concentrations of 0.18 and 0.30 pCi/g-dry at station llAl during June and August. Detectable Sr-89 activity of 0.4 pCi/g-dry was also observed at control location 12Cl in the Auqust sample. The June sample at the control location 12Cl was l_ess than 0.1 pCi/g-dry. Therefore, the concentrations of Sr-39 observed at the indicator

• station (0.18 and 0.3 pCi/g-dry) are similar to those observed at the cont1~01 location (<0.1 and 0.4 pCi/g-dry). /l.11 the shell samples contained Sr-90 concentrations ranginq beh:een 0.15 and 0.32 pCi/g-dry. Because strontiur-1 concentrations in skeletal structures, fhe shells of the crabs are expected to contain higher levels of radiostrontium than the flesh. Observable

• • radi ostronti urn activity at both 1oca t"ions indicate that the probable source for the Sr-89 and-90 can be attributed to world-wide fallout from nuclear weapons testing.

Small fish species (prey fish) \'lhich serve as a primary food source for larger edible species were sampled. Total samples (flesh and bones) were analyzed for gamma emitters, and Sr-89 and Sr-90. Detectab 1 e concentrations

~* of K-40 were found in all samples, averaging 2900 pCi/kg-1*1et, similar to the 2800 pCi/kg average for edible fish. Concentrations of Sr-89 were below the MDL (0.01 to 0.20 pCi/g-wet) in all but one sample. The detectable Sr-39 concentration was 0 .13 pCi I g-wet, which is ~*Ii thin the range of the MDL values of the other samples. Strontium-90 was detected in one of six samples. The 1.,. detectable level in this sample (0.004 pCi/g-v1et) also fell 1vithin the MDL range ( O. 004 to 0. 04 pCi I g-1<1et) of the other samples.

Benthic organisms were collected at four locations and analyzed for Sr-39 and~90. Since only small samples were available, analytical results *vary considerably. Strontium-89 was detected in one of six samples. The detectable

~*- activity 1*1as 20 pCi/g-dry, which was bet\*Jeen. the MDL range (0.7 to 2370 pCi/g-dry) of the other samples. Two of six samples shm'led detectable Sr-90 concentrations of 0.1 pCi/o-dry and Q.3 pCi/g-dry. These detectable activities*

are below the MDL range (0.8 to 309 pCi/g-dry) of the other four samples.

The MDL for radiostrontium as required by the Environmental Technical

). Specifications for benthic orgunisms cannot be met in any of the samples due to the impracticality of obtaining a large sample size of benthic.organisms.

Sediment I

Sediment was coll ec'i:ed semiannually at four locations and analyzed for gamma emitters and Sr-90.

Results of gamma spectrometry shO\*Jed detectable levels of a variety of naturally occurring radionucl ides as well as man-made radionucl ides. The various fallout nucl ides \*1ere observed intermittentlv at control stations as well as at indicator stations. With the exceptior1 of Cs-137, 1vhich ranged between 0.04 and 0.25 pCi/g-dry, no other fallout nuclide \'1as detected in more than 20% of the s amr l es. Mangunese-54, \'lith a. detectable co11cc11t1~a ti on of 0.02 pCi/g-dry at control location 12Cl, v1as the only nuclide observed in 1977 that \'/as not detected during the preoperational period.

No Sr-90 was observed in any of the eight samples analyzed, with the l~DL ranging bet\'/een 0.03 u.nd 0.06 pCi/g-dry.

All results observed in the aquatic samples analyzed in 1977 showed no apparent differences from results observed during the preoperational period.

Atmospheric Environment The atmospheric environment in the vicinity of Artificial Island was examined by analyzing samples of air particulates, air iodine) and precipitation.

• Air particulates were ~ollected at eight stations, while air iodine cartridges were collected at seven locations. Precipitation was also collected at one of these locations ~ the Salem Substation .

• • Air Particulates Weekly air particulate samples were an~lyzed for alpha and beta emitters.

Quarterly composites of the \'Jeekly samples from each station were analyzed

• • for Sr-89, Sr-90 and gamma emitters. Due to a temporary laboratory problem Sr-89 and-90 and gam11a emitter analyses for the fourth quarter include only December samples. The results of these analyses and subseciuent garrma emitter analyses of the October and November samples are included in this report.

Results of Sr-89 and-90 analyses for the October and November samples were not yet available but will be included in an amended report. '

Of the 102 weekl)i air pa.rticulate samples (2 stations) analyzed for alpha emitters, 85 sho\'/ed *detectable concentrations. The range of a 1pha activity was from <0.0002 to 0.0026 pCi/m 3 and averaged 0.0012 pCi/m 3

• Weekly gross3 beta analyses showed conceritrat ions ranging from 0. 023 to

• • 0.540 pCi/m , with the average for the 8 sampling stations being 0.144 pCi/m

• In addition to normal seasonal fluctuations, increased activity was noted 3

in early October and was directly attributed to fallout from the September 17 atmospheric nuclear weapons test. Figures 3 and 4 show the relation bet\*1een gross beta and preci pi tu. tion for the preopcrationa l versus the opcrationa 1 periods, showing both seasonal and weapons-testing fluctuations.

Results of garrma spectrometry showed detectable levels of several radionuclides, both naturally occurring and man-made (Be-7, K-40, Mn-54, Cr-51, Co-58, Co-60),

ZrNb-95, Ru-103, Ru-106, Sb-125, 1-131, Cs.-137, BaLa-140, Ce-141, and Ce-144) *

• A11 garJJtJa-emitting nuclide concentrations observed were below or similar to those con,..

centrations noted during the preoperational _period, with the exception of Co-58 and 1-131. Co-SB was observed in the 3rd quarter composite sample from station 5Sl .~ith ~

decay corrected concentration of 0.00034 + OtJ00026 pC.i/m?.. This concentration fs not different from the MOL valves encountered-nt other stations during this period~ This

• concentration is probable not *plant related since no other detectable amounts of Co-58 were observed during the third quarter. In addit1on Co-58 was detected in the October-November cc-mposite samples at locations SSL.and 16El.. The decayed corrected concentrations at these locations were 0.00013 and 0.00015 pCi/m3 respectively. The Co-58 observed is most probably attributed to the world wide fallout resulting from the -

atmospheric nuclear weapons test of September 17, . .1977. Iodine-131 was observed in~a

• December composite sample at station 1001 with a concentration.of 0~0?4+o.Ol0 pCi/IIT"'.

Since no gaseous I-131 was observed during the period and SNGS did not release any detectable I-131 during 1977 (i2,13) it can be concluded that this incident was not plant related. Garrma analyses were performed on three additional ~eekly air particulate samples from stations 251, lFl and 2F2 for the week of September 19 through September 27.* These

• samples were analyzed for gamma emitters in accordance ~tith the Sr~GS technical specifi-cations because the beta activity in these samples exceeded the control location activity by a factor of.four .. It was determined that the reason for the difference was a low sample voll.Slle at the control location. Results of these analyses .are found in table 36 *.

All garrma emitters observed in these weekly samples were similar in concentration to those

• observed in the quarterly composites except for two nuclides. Iodine-131 of undermined origin was observed in the filter collected at station 251 at a decay-corrected concen-

. tration of 0.047+0.027 pCi/m3. The above-mentioned I-131 was detected in a particulate form, and, in adaition, no gasesous I-131 was observed during this period from 251. There fore, it is probably that this incident was not plant related *.. The pther gamma-emitting

.nuclide Bala-140, was observed in all of the special analyses *

• . The radiostrontilill analyses perfonned on the quarterl~~composite*s shO\ied ..detectable * * * :.

levels of Sr-89 ranging between 0.0009 and 0.013 pCi/mv, with the average for the first-.

three quarters being 0.0053 pCi/m3 while Sr-90 ranged between <0.0003 and 0.0026 pCi/m3 ~

with the average being .0.0011 pCi/rn3. The activities noted are the result of the recent atmospheric nuclear weapons testing since the fall of 1976 and are not related to the .. *-~

• .operation of SNGS since the effluent release records of SNGS indicate that less that SxlO" He; of radiostrontium was released during the later part of 1977. (13) ..

The results of all air particulate analyses did not differ, except where noted above, from preoperational results, n()r were any significant differences between indicator and * *.

ind.icator and control stations observed

.Iodine cartridges were connected in series behind eachof the air particulate filtersfor adsorption of gaseous iodine. The adsorption media used in these cartridges was 11 TEDA 11 impregnated charcoa 1. Eighteen of 339 cartridges 14 I

~.

• analyzed had detectable concentrations of 1-131 ranging between 0~00313 and 0.031 pCi/m 3

• The rhajority of the detectable 1-131 was observed in January at both control andindicator stations. The 1-131 observed can therefore be attributed to the world-wide fallout from the nuclear \*tepaons testing in the

• fall of 1976. One additional week of detectable 1-131 activity was noted in

• October. This again was observed following the September 1977 nuclear weapons testing. No additional 1-131 activity was observed throughout the reporting period.

Preci pi tat ion /

• Although not specifically required by the Salem ETS, precipitation 1*Jas sampled continuously and collected monthly at the Salem substation sampling location.

Concentrations of H-3 in these samples ranged from <80 to 195 pCi/l. The concentrations of alpha emitters were below MDL (1.5 pCi/l) in seven of the t\*telve samples. The other five samples had alpha concentrations .ranging between 0.7 and 12 pCi/l.* Beta-emitter concentrations ranged from <3.7 to

• 776 pCi/l and averaged 107 pCi/l. Th*e highest activity of both the alpha and beta (12 and ?76 pCi/l, respectively) was found in the May sample and had elevated results due to the extremely low sample volume*.

• Quarterly composites of precipitation \~ere analyzed for r_adiostrontium and

• gamna emitters.* The gamna emitters detected \'/ere naturany occurring Be-7 and K-40 while the man-made nu cl ides observed were ZrNb-95, Ru-103, Cs-137, Bala-140> Ce-141 and Ce-144 *. Most of the nuclides were detected in the third quarter sample, which included samples that were affected by the September atmospheric nuclear weapons test. The Sr-89 levels ranged between <4.5 and 7.8 pCi/l, while those for Sr-90 ranged from <0.5 to 2.4 pCi/1. These levels

'* indicate fluctuations resulting from atmospheric nu cl ear weapons testing in 1976 and 1977 *

.Terrestrial Environment The terrestrial environment in the vicinity of Artificial Island was exal!lined

,. by analyzing samples of well water, raw. and treated potable water, milk, fruits, vegetables, beef, fodder crops, game, b~ef thyroid tissue, and soil.

Well Water

~. Monthly well water samples were taken from an on-site (indicator) well. and*

two off-site (control) wells. -All well water samples were analyzed for fl-3, alpha and beta activity, and K-40 (atomic absorptidn). Quarterly composites were analyzed for gallilla emitters, and Sr-39 and Sr-90. *

• Detectable* concentrations of H-3 were observed in eleven of 36 samples ranging:

• The only nuclide detected by garrnm spectrometry was K-40 (lo to 16 pCi/l) in three of twelve samples. Strontium-89 wus detected in the second ciuartcr sample from locations 451 and 501 with a concentration at or lower tha11 the MDLs of the other 'iO samples, 1*1hich ranged between 0.5 pCi/l and 1.1 pCi/l.

One detectable Sr-90 activity ~tas observed with a concentration of O.G pCi/l.

• This again is within the range of MDLs for Sr-90 (0.3 pCi/1 to 0.7 pCi/l) .

Po tab 1e Hater Both raw and treated water samrles \'/ere taken at the Salem Hater Comrany, the only drinking 1*1ater processing plant in the vicinit.Y of Ai~tificial Island. The

• ra\'/ 1:Jater source for this plant is Laure*! Lake (a tributary of the D~la1*mre River) and several adjacent 1J1clls. Potable 11ater samrles were anulyz2d monthly for H-3, alpha and beta activity, and K-40 (atomic absorption); Sr-89 and-90, and gamna emitters were analyzed on a quarterly basis.

The concentration of H-3 averaged 143 pCi/l for all analyses, with no signif*icarrt

• differences between the raw and treated samples. Detectable alpha activity was observed in 17 of 24 samples ranging between 0.4 pCi/1 and 1.8 pCi/l in all samples. Beta and K-40 concentrations were 101*1er than in the saline surface water, as is usual for fresh water, with K-40 generally contributing less than 50% of the beta activity. The average gross beta concentrations \*:ere 4.5 pCi/l (ravl) and 5.1 pCi/l (treated). The average K-40 i~esults \'Jere 1.4 pC-i/l (ra1"1)

• and 1.7 !JCi/l (treated).

Eight quarterly comros ites 1*1ere analyzed for Sr-89 and-90, and gamr;ia e:.iitters.

Two detectu.bl e concentrations of Sr-89 1*1ere noted, l'lhi ch were bet1*1ecn the MDL range (0.9 pCi/l to 1.9 pCi/1) of *the other sa~ples. Strontium-90 was observed in seven of the eight samples with the concentrations ranging between 0.5 pCi/1

• • and 1.0 pCi/1. No garrrna emitters were detectc:d in any of these samrles. \,later treatment had no significant effect on any of the analytical parameters measured.

No annual trends in the radiological characteristics of potable water were

.observe.d.

• • Milk Milk samples were taken twice.a month from five local farms during 1977 and analyzed for I-131; gamna emitters, Sr-89, and Sr-90 were analyzed monthly.

Following the nuclear weapons test of September 17~ additional milk srimples were collected in order to meet the ETS requirc:rnents concerning collection

-* during time of elevated I-131 *concentrations.

• Detectable concentrations of I-131 were observed in 30 of 37 samples collected from all stations beti-Jeen the last \I/eek of September through the f-irst collection in December. The I-131 observed rangc:d bet1-1een 0.29 and 25.00 pCi/l and was attributed to the world-wide fallout from the.September 1977 nuclear wea~ons

• • test. Figure 5 shows the average I-131 concentrations in milk samples resulting from three atmospheric nuclear wearons tests by the Peoples Republic of China between June 1974 and September 1977. No other I-131 was observed in any of the samples .

Two incidents concerning I-131 in.' milk samples were reported in 1977. In all cases. the r-131 concentrations at the various indicator locations were a factor of ten greater than was the concentrati.on at the control location. The first

• incident occurred *with the October 17 and 18 sample collected at station 2Fl.

Th*e second occurred with th~ November 6 and 7 samples collected at stations 5F2_,

2Fl and 15Fl *. It was concl~ded that the cause of reportable I-131 was world-wide nuclear fallout from the September 17 nuclear weapons test si11ce SNGS did not

• release detectable I-131 during this reporting period (12.13) .

• Gamma spectrometry showed detectable concentrations of K-40 in all samples and of Cs-137 in all but five of the sixty samples analyzed. The annual average concentrations were 1400 pCi/l fo~ K-40 and 2.8 pCi/l for Cs-137 .. These levels were not significantly different between stations." Iodine-131 was the only other gamna-emitting nuclide detected during 1977. Observable levels

• were detected in the October samples following the September nuclear weapons test and ranged from 14 to 45 pCi/l.

Strontium-89 was detected in seven cf the fifteen samples analyzed follm'ling the s*eptember nuclear weapons test, with results ranging between <4.4 pCi/l and 15 pCi/1. The concentration of Sr-90 exceeded the MDL in forty six of the

• sixty samples analyzed and averaged 2.3 pCi/l. Seven Sr-89 analyses did not meet the required s.ensitivity because th~ MDLs were decay corrected. Presently, a study is being conducted to verify the accuracy and precision of the strontium methodology.

Game

• Five game samples (4 muskrat, 1 *deer) were* taken* during this period. *Flesh from all five samples was analyzed for ganrna emitters while bones from the muskrats were analyzed for Sr-89 and Sr-90. Naturally occurring K-40 \'las detected in all five samples ranging from 0.7 to 3.7 pCi/g. In addition,

• Cs-137 was present in tM> of the five samples.. Muskrat bones showed

• detectable Sr-39, with concentrations ranging between O. 6 and 1.2 pCi/ g-dry.

Detectable Sr-90 concentrations were observed in all samples ranging from 0.5 to 1.0 pCi/g-dry.

Food Products A wide variety of other human food products was samp 1ed and analyzed for gamma emitters, and Sr-39iand-90. These included cucumbers, asparagus, peppers, corn, tomatoes, sciuash, and eggplant. All samples containeJ K-40 at conccntrntions from 1.0 to 3.5 pCi/g-wet. One squash snmple at control station 1G2 contained

• a detectable.level of Cs-137:, while one asparagus samrle collected from station 2El shovJed a detectable amount of Zrf~b-95. l~o other qamr;1a emitters \vel'e detected in those food products. ,L\ll analyses for Sr-89 were belo\'/ tile MDL (4 pCi/kg to 40 pCi/kg). Conce11tratio11s of Sr-90 \'!ere detected in the asparagus snmple (4 pCi/kg), v1hich is similar to concentrations obsei~vcd during the preoperationu.l

• period .

Fodder Crops Eleven fodder crop samples were taken at 7 local farms and analyzed for gamna

-. erni tters. Gamma spectrometry of these samp 1es shm1ed a vciri ety of radi onucl ides, both man made and naturally occurring. Of the naturally occurring gamma emitters present, only K-40 1*1as observed in all samples, \lith an average of 15 pCi I g-dry. Other detected naturally occurring nu cl ides 1*1ere Be-7 and Ra-226. The man-made nucli<les Mn-54, Zr-95, Nb-95, Ru-103, Ru-106, Sb-125, Cs-137, Ce-141, and Ce-144 were also observed. \*Jith the exception of Mn-54 and Ru-103, a 11 wer-e observeu during the preorerati ona 1 period. l ia11ga11ese-St1, 1

All r1an-made radi 011ucl ides a re ass urned to be from the residual world-\'tide fallout from the 1976 nuclear 1*1earons tests since all \'/ere detected in the preoperational air particulate samples collected following the above-mentioned tests .

• Soil Fourteen soil samples were analyzed for gamma emitters and Sr-90. Gamma spectrometry of these samples showed detectab 1e co11centra ti ons of the na tu rally occurring nuclides (K-40, Ra-226, and Th-232) and the fission products Cs-137 and Ru-103. The Cs-137 concentration averaged 0.70 pCi/g 1*1itll a range from 0.11 to 3. 7 pCi/g. Rutheni um-103 was detected in onf; sample at a concentration of 0.02 pCi/g, which was just above the MDL (0.01 pCi/g). All other gamma emitters were at or below their respective MDLs. The concentr~tions of Sr-90 ranged from 0.06 to 0.68 pCi/g with an average of 0.16 pCi/g.

=* Direct Radiation Direct radiation measurements were made at 24 locations using CaS04(Trn) thermo-luminescent dosimeters. During 1977, 283 monthly and 96 quni*terly TLD packets

. e were collected. Each packet included four dosimeters for a total of 1536 analyses. These <<nalyses resulted ill an average *dose rate of 5.09 mrads/standard month for monthly TLDs and 4.90 mracls/standard month for quarterly TLDs. All TLD results rresented in this report have been normalized to a standard month (30.4 days) to elimiriute the apparent differences caused by variations in exposure periods. A comparison of the direct radiation data for 1977. sllm*1s a

• simili1rity bet1veen the average monthly dose for both indicator stations (tJ..97 mrem/std. month) and control stations (5.64 mrmn/std. month). These rest1lts compare favorably to the preoperatio1rnl results as shmm in fi011res G and 7, therefore, i ndi ca ting no effect from SNGS opern ti 011.
