SUMMARY

During the per.iod from January l through December* 31, 1986;. the*. Research* and Testing Laboratory (RTL), PSE&G Research Cor.po-ration, has been responsible for the collection and analysis of all samples and the maintenance of sampling equipment connected with the Radiolog_ical Environmental Monitoring Program (llEMP'); at Artificial Island, Salem County, New Jersey. This program was designed to identify .and quantify concentra~ tions of radioactivity in various environmental media and ta quantify ambient radiation levels in therenvirons of Artificial Island. Due to the proximity of the Salem~and Hope Creek Gener-ating Stations a common REMP is beinci' co.hducted. Salem Gene.r-ating Station (SGS) Unit One became* crit:ic!al on December 11., 1976, thereby initiating the operational phase of the REBPo Data collected during the operaJ:,ion,al! phase served as a sourc:e.- of preoperational data for Salem Uqit ~wo and the Hope Creek Generating Station. Salem Unit Two achieved initial criticality on August 2, 1980 and the Hope Cre~k :G:enerating Station achieved initial criticality on June 28, 19:~6 ~ '! This report presents the results of thermoluminescent dosi~~t~i arid radiological analyses of environmental samples collected~d~iing 1986.

:; ..

A total of 4091 analyses were perf'ormed on 1615 environment.al samples during the period covered' by .this report.- Samples of air particulates, air iodine, surface, ground and drinking water, benthic organisms, sediment, milk, fish, crabs, vegeta-bles, game, fodder crops, meat, soi1,:* and precipitation were r: collected. Thermoluminescent dos~meter$ were* used to measure ambien~ radiation levels. Ambient radiation levels remained .at normal levels observed in previous years until May 9, 19~~ when radioactivity from the Chernobyl-4 reactor accident wa~ detected. According to reports provided to Western scientists at:the International Atomic Energy Agency conference on Chernc;>byl held in Vienna, Austria, it is now known that the accident occurred as a result of a

.   ;_ '
     -~

poorly planned reactor experiment. Soviet plant personnel I deliberately took actions which blocked the plant's safeguard

      .   '        systems that would have automatically prevented the accidento
**: .. i This action resulted in a reactivity excursion accident in which the reactor became prompt c;ri.tical [ 24 I. The excursion resulted in a power escalation which resulted in fuel melting and finally
         -,        a steam explosion which prdp~lled fuel fragments, activation products and burning graphite into the environmente The intense heat of the graphite fire.provided a mechanism for the radio~

active fission products and activation products to_ become_. sufficiently buoyant to enter :the upper atmosphere [ 25].

     '.*:~         Actions taken to fight the fire resulted in additional destruc~

tion of.the core which caused*airborne releases into the environment to fluctuated by several orders of magnitude for several days after the accident~

Estimates*: of projected :I-131 concentrations :i;n milk*. in the. town .... of Pr ipyat, . USSR. were .'reported*. as :high as 10 3, 700 ,*ooo pCi/L [ 25 l ~.

The Soviets arid the Scandariavian countries.also.repcirted measur--

ing excessive concentrations of radioactivity in.soiis,, reindeer flesh, fish, wells, rainwater and goat milk.* .Since all releases from*our nuclear stations were within our technical -specifica-tions, the increases in radioactivity a~ measured in various environmental media in the vicinity of the Artificial Island were due to the accident at Chernobyl-4 and not to the operation of the Salem or Hope Creek. Generating Stations *. INTRODUCTION Artificial Island is the site of Salem and Hope Creek Generating Stations. The Salem -Generating Station (SGS) consists of two operating pressurized water nuclear power reactors. Salem Unit One has *a net rating of 1090 MWe (3338 MWt), and Salem Unit Two is rated at 1115 MWe (3411 MWt). The Hope Creek Generating Station (HCGS) is a boiling water nuclear power reactor which achieved initial criticality on June 28, 1986. The Hope Creek Unit has a* net rating of 1067 MWe (3293 MWt). Artificial .Island is a* man-made peninsula on the east bank of th Delaware River and was created by the deposition of hydraulic fill from dredging operations. It. is located in Lower Alloways Creek Township, Salem County, New Jersey *. The environment

surrounding Artificial Island is characterized mainly by the Delaware River and Bay, extensive tidal marshlands, and low-lying meadowlands. These land types make up approximately 85% of the land area within five miles of the site. Most of the remaining land is used for agriculture [7,8]. More specific informatfon

Since 196a an off-site Radiological Environmental M6nitoring Program (REMP) has beeri conducted at the Artificial Island Site.

                                                       *Starting in December* 1972, more extensive radiological monitoring programs were. initiated. The operational REMP. was initiated in December 1976 when Salem Unit 1 achieved criticality. The

- From January1 1973, through. June, ,.1983 1.. Radiation Management
Corporation (RMC) had primary responsib-ility. for _the analysis of all samples under the Artificial. Island REMP and the annual reporting of* results.
RMC reports for the *the preopera tional phase from* 197 3 to 1976 and for *the operational phase from 1976 through 1982 are referenced in this report [l-3]. On July 1, 1983, the RTL assumed primary responsibility.for the analysis of all samples (except TLD's) arid the reporting of results.

Teledyne Isotopes (TI), Westwoo9, NJ, at that time was made responsible for third-party QA analyses and TLD's *. RTL reports for the operational phase from i983 to 1985 are refere~ced in this report [4~6].

This report, as required by Section 6.9.1.10 of the Salem Technical Specifications, and Section 6.9.l.,6 of the Hope Creek Technical Specifications summarizes the findings of the 1986 REMP. Results of the four-year preoperational program which was conducted prior to the operation of any reactors on the Arti-ficial Island have been summarized for purposes of comparison with subsequent operational reports [2]. Sample Collection In order to meet the stated objectives, an appropriate opera-tional REMP .was developed." samples of var.ious media were selected to obtain data for the evaluation of the radiation dose to man and other organisms *. The selection of sample types was bas~d on: (1) established critical pathways for the transfer of radionuclides through the environment to man, and .(2) experience gained during the preoperat.ional phase. Sampling l.ocations were determined from site meteorology,* Delaware estuarine hydrology, local demography, and land uses~ Sampling locations were divided into two classes - indicator and control. Indicator statioris are those which are expected to manifest station effects, if any exist; control samples are collected at locations which are believed to be unaffected by station operations. Fluctuations in the le~els of radionuclides and direct radiation at indicator stations are evaluated with respect to analogous fluctuations at control. stations. Indicator and control station data.are also evaluated relative to preoper-ational data. Air particulates were 'collected on Schleicher-Schuell No. 25 glass fiber filters with low-volume air samplers. Iodine was collected from air by adsorption on TEDA-impregnated charcoal cartridges connected -in series after the air particulate filters. Air sample volumes were measured with calibrated dry-gas meters and were corrected to standard temperature and pressure. *

times one standard deviation of the background count or of the blank sample count as appropriate. The grouped data were averaged and standard deviations calculated in accordance with Appendix B of Reference 18. Thus, the 2 sigma deviation* of the averaged data represent sample and not analytical variability. When a group of d~ta was composed Of 50%* or more LLD values, averages were not calculated. Grab sampling is a useful and acceptable procedure for taking environmental samples of a medium in which the concentration of radionuclides i~ expected to vary slowly with time or where intermittent sampling is deemed sufficient to establish the radiological characteristic~ of the medium. This method, however, is only representative of the sampled medium for that specific location and instant of time. As a result, variation in the radionuclide concentrations of the samples will normally occur. Since these variations will tend to counterbalance one another, the extraction of averages based upon repetitive grab samples is considered valid.

Quality Assurance Program PSE&G Research Corporation, Research and Testing Laboratory (RTL), has a quality assurance program designed .to maximize confidence in the analytical procedures used. Approximately 20%

of the total analytical effort is spent on quality control, including process quality control, instrument quality control, interlaboratory cross-check analyses, and data review. The analytical methods utilized in this program are summarized in Appendix* D. The quality of the results obtained by the RTL is insured by the implementation of the Quality Assurance Program as described in . the Environmental Division Quality Assurance Plan [19,20] and the Environmental Division Procedures Manual [21]~. The internal

quality control activity of the Laboratory includes the quality control of instrumentation, equipment and reagents; the use of reference standards in calibration, documentation of established procedures and computer programs, and analysis of duplicate and spiked samples. The external quality control activity is imple-mented through participation in the USEPA Laboratory Intercom-

Results of gamma spectrometry indicated detectable levels o~ Be-7 in all of the 32 monthly composites, with a maximum of 110 x lo-3 pCi/m3. Berylium-7 is a naturally-occurring radionuclide attributed to cosmic ray activity in the atmosphere. During this reporting period detectable levels of Ru-103, Ru-106, cs-134, Cs-137, Ra-226, and Th-232 were noted in many of the locations sampled. Ruthenium-103 levels ranged from 7.5 x lo-3 to 9.2 x lo-3 pCi/m3. Ruthenium-106 levels ranged from 4.0 x lo-3 to 8.3 x lo-3 pCi/m3. Cesium-134 levels ranged from 8.4 x lo-3 to 10 x lo-~ pCi/m3. Cesium-137 levels ranged from 16 x lo-3 to 18 x lo-3 pCi/m3. In reviewing the data it is noted that Ru-103, Cs-134 and cs-137 levels increased significantly during the second quarter of 1986. The Ru-103; Cs-134 and cs-137 increased levels are not attribut-able to the operation of the Salem or Hope Cr~ek Generating

    -"    *. i Stations. Based on their respective effluent release reports, there were no releases of Ru-103, Cs-134 or Cs-137 during the second quarter (22,23]. The increased levels are attributable to the Chernobyl-4 reactor accident. since similar concentrations existed at indicator arid control station locations

Radium-226 was also detected in one of the samples at a concen-tration of 1.2 x lo-3 pCi/m3, which is within the variations

Direct Radiation (Tables t-8, c-9) A total of 41 locations were monitored for direct radiation during 1986, including 6 on-site locations, 29 off-site locations within the 10 mile zone, and 6 control locations beyond 10 miles. Monthly and quarterly measurements were made at the 6 on-site stations and at 15 off-site indicator stations~ and 3 control. stations. An additional 14 quarterly measurements were taken at* schools and population centers with 3 additional controls beyond the 10 mile zone in Delaware. Fou*r readings for each TLD at each location were taken in order to obtain a more statistically valid result. The average dose

rate for the 15 monthly off-site indicator Ttn*s was 5.8 milli-ra:ds per standard month, and the corresponding averaged control.

dose rate was 6.4.millirads per standard month. The average dose rate for the 29 quarterly off-site indicator TLD's was 5.1 millirads per standard month, and the averaged control rate was 5.6. For these measurements, the rad is considered equivalent to the rem, in accordance with 10CFR20.4. In Figure 2, the average radiation levels are plotted for the 13 year period through 1986. Figure 2A shows the* monthly averages of the off-sit~ indicator stations and the control stations for 1982 through 1986. Ambient radiation levels during 1986 were comparable to those obtained during 1985. I Terrestrial Milk (Tables C~lO, c-11, C-12) Milk samples were collected in accordance with the Salem and Hope Creek Technical Specifications at six local dairy farms. During this reporting period, one dairy operator terminated operations (location 2F4) and, as required by the SGS and HCGS Technical . Specification, a replacement location (lbcation 2F7) was found and added to.the surveillance program. Samples were collected semi-monthly* when cows were on pasture and monthly when cows w e r . ... not on pasture. . . . . . .

Each sample was analyzed. for .I:""l31 and gamma emi t.ters. I.n. addi-tion, aithough not* sp.ecif ic~lly required by the SGS and. liCGS Technical* Specifications,*~ne sample from each location was analyzed for:: -Sr..;.89 and Sr-90 in order to maintain the data base developed *in prior years. All sr-89 results were below detect-*

able levels. Strontium-90 results were comparable at indicatar and control locations and averaged 2.1 pCi/L. Following the nuclear accident at the Chernobyl-4 reactor in the Soviet Onion,* iodine-131 levels increased significantly. Esti-mates of the quantity of I-131 released from the Chernobyl-4

                ..      reactor indicate that as much as 20% of the core inventory of
             '          I-131 could have been discharged (25]. Samples collected during the third week in May and analyzed for I-131 using an ion
                      ' exchange resin method, ranged between 11 and 53 pCi/L with the highest result obtained at the control station location. The elevated levels persisted during June and the first week of July.
    ;

The mean of the indicator locations which had detectable levels of I-131 was 10 pCi/L while the mean at the control locations

  ;'        :           which had detectable concentrations of I-131 was 19 pCi/L.

Levels of I-131 iri milk did not return to normal levels until the

 ..                     third week of July. All other samples collected during the year
                 *,     indicated no discernible I-131 activity. Figure 3 and 3A shows 11 the average I-131 activity measured during this year compared to results obtained in.previous yearso Table c~10 lists the results and shows that sensitivities ranged from <Ogl to <0.8 pCi/t. ..

Gamma spectrometry showed detectable concentrations of naturally= occurring K-40 in all samples. The annual mean concentration measured at indicator locations averaged 1400 pCi/L, and the annual mean concentration measured at control locations averaged 1400 pCi/L~ Sodium-22 was detected in one sample in May at a concentration of 4.6 pCi/L. The Na-22 LLDs for all stations ranged from <l.O to <6.4 pCi/L. Manganese-54 was detected in only one sample at a l~vel of 2.9 pCi/L. The Mn-54 LLDs for all stations ranged from <0.7 to <4.9 pCi/L. Zinc-65 was detected in only one sample ~t a concentration of 11 pCi/L. Cesium-137 was detected in six samples at levels which ranged from 3.3 to 5.1 pCi/L. Since the cs~l37 LLDs for all stations ranged from

Well Water (Tables c-14, C-15, c-16) Although wells in. the vicinity of the Salem and Hope Creek Generating Statiori are not anticipated to be affected by plant operations, water samples were collected monthly from two indi-cator wells and one control well. Each.sample was analyzed for gross alpha, gross beta, tritium, potassium-40 and gamma emitters. Quatterly composites were analyzed for.radiostrontium. Gross ~lpha concentrations from 0.6 to. 2.D pCi/L were de~ected in seven of the.indicator locations, with LLD sensitivities for the other analyses ranging f~om ~0.5 to <3.7 pCi/i. G~o~s beta activity was detected in all of the samples. The mean activity for the iridicator locatio~s wa~ 7.6 pCi/L with a range of 2.0 to ts pCi/L; mean activity for the control location was 7.4 pCi/L with a range of 2.5 to 9.5 pCi/L.

Potable Water. (Tables C"'."'17,

C-18, c-19)

Both raw and treat~d water samples were collected from the Salem water treatrnenb.plant. Each consisted. of daily aliquots composited into a monthly sample. The* raw water source for this plant is Laurel Lake and adjacent wells. Each sample was analyzed for gross alpha, gross beta, K-40, tr.itium, and gamma emitters. Quarterly composites of raw and treated water were analyzed for sr-89, sr-90. Detectable alpha activity was noted in eleven water samples at concentrations ranging from 0.5 to 1.5 pCi/L; LLD sensitivities ranged from <0.5 to <2.4 pCi/L (raw), and from <0.5 to <l.9 pCi/L (treated). Beta activity was observed in all of the 24 monthly samples witp ranges of 2.0 to 13 pCi/L (raw), and 1.7 to 8.2 (treated), and averages of 3.6 pCi/L (raw) and 3.6 pCi/L (treated). Potassium-40 concentrations for raw and treated samples *were similar but lower than the gross beta activity in all cases. The K-40 average for the raw and treated samples was 1.6 and 2.0 pCi/L respectively. Tritium activity was observed in one of the twenty-four samples at a concentration of 150 pCi/L. strontium-89 was detected in one of the eight quarterly composite

water samples at a concentration of 0.8 pCi/L; LLD sensitivities ranged from <0.5 to <l.6 pCi/L for Sr-89. Strontium-90 was not detected in any of the water samples and the LLDs ranged from

                              <0.4 to <l.O pCi/L for Sr-90. Gamma spectrometry detected Ru-103 in one sample at 2.6 pCi/L; Ra-226 in three samples at concentra~

tions ranging from 2.6 to 8.4 pCi/L; and Th-232 in three samples at concentrations ranging from 5.7 to 6.8 pCi/L. The LLDs ranged from <0.5 to <5.6 pCi/L for Ru-103; .from <3.7 to <5.8 pCi/L for Ra-226 and from <4.9 to <9.6 for Th-232. Food Products (Table C-20) Although vegetables in the region are not irrigated with water in which liquid plant effluents have been discharged, a variety of food products grown in the area for human consumption were sampled. These included sweet corn, peppers, asparagus, cabbage, and tomatoes *

 .1 All samples contained naturally occurring K-40 at concentrations from 910 to 3400 pCi/kg~wet, with an average for all samples of 2100 pCi/kg-wet. Berylium-7 was detected in one sample at a concentration of 24 pCi/kg=wet. Iodine-131 was detected in one indicator location and one control location at levels of 33 and 62 pCi/kg-wet for samples.collected during May.

A trace of Cs-137 was detected in tomatoes from two control stations ~t 1.5 and 2.1 pCi/kg-wet. Since the LLD sensitivities ranged from <l.6 to <24 pCi/kg-wet, the detectable levels of Cs-137.are not considered as being significant. Concentrations of Ra-226 were detected in three samples ranging from 8.3 to 68 pCi/kg-wet. The two highest concentrations measured occurred at two different control locations at concentrations which were comparable. to *the LLD-values. The LLD values ranged from <1.8 to

                                       <51 pCi/kg-wet. Thorium-232 was detected i~ one tomato sample at a concentration of s.s*pci/kg-wet~ The LLDs ranged from <5.5 to <110 pCi/kg-wet for a variety of food products collected during the reporting period.

Potassium=40. was detected in all of. the nine samples* at con*cen~ trations. ranging from 2300 to. 15000 pCi/kg-wet, wi_th an average:* af 7000 pCi/kg-wet. Berylium-7, from the atmosphere, was found .. in five of the samples at concentrations. ranging from 37D to 1400 pCi/kg-wet. Cesium-137 was detected in one of our control loca-tions at a concentration of 13 pCi/kg-wet. The LLDs for Cs-137 ranged from <17 to <54 pCi/kg=wet. Radium-226 and Th~232 wer::e detected in two different samples at a concentrations of 35 and 170 pCi/kg-wet. The LLDs for the Ra-226 ranged from <36 tQ <lGO pCi/kg-wet while the LLDs for Th-232 ranged from <59 to <l3U pCi/kg-wet.

Soil (Table C-23)

Soil is sampled every three years at 16 locations, including two controls, and analyzed for Sr-90 and gamma emitters. Sanples are collected at each station in areas that have been relatively undisturbed since the last collection in order to determine any change in the radionuclide inventory of the area. The concentrations of sr-90 for the indicator stations ranged from 27 to 140 pCi/kg-dry with an average. of 91 pCi/kg~dry... The two control stations yielded results of 56 and 130 pCi/kq~dry with an average of 93 pCi/kg. Since the purpose of these samples is to determine if the operation of the nuclear stations is resulting in an increase in the inventory of long lived reactor produced radionuclides in the environment, the values obtained were compared to data reported in previous years. Averages for the indicator stations were 220 pCi/kg in 1977, 149 pCi/k~ in 1980, and 125 pCi/kg in 1983. Averages for the control stations were 430 pCi/kg in 1977, 195 pCi/kg, and 93 pCi/kg in 1983. The gradual decrease is perhaps attributable to the wash~out and decay of weapons testing fall-out from the l950's to the 1960 9 s. Gamma spectrometry of these samples showed detectable concentra-tions of the naturally occurring radionuclides (K~40, Ra-226, and_ Th-232) and the fission product Nb-95 and cs~l37. The Nb-95 concentrations found ranged from 34 to 63 pCi/kg with an ave~aqe of 48 pCi/kg. These results are comparable to measurements obtained during the preoperational studies in which levels* of Nb-95 of 90 pCi/kg were observed [2]. The cs-137 at the indicator stations ranged from 78 to 1500 pCi/kg with an average

              - Aquatic surface Water   ( Tabies

c-24, c-25., c-26, C-27 ).

Surface water samples were collected morithly at five locations in the Delaware estuary. One location is at the outfall area, another is downstream from *the outfall area, and another is directly west of the outfall area at the mouth of the Appoquini-mink River. Two upstream locations are in the Delaware River and at the mouth of the Chesapeake and Delaware Canal, the latter being sampled when the flow is* from the Canal into the river. Station 12Cl, at the mouth of the Appoquinimink River, serves as the operational-control. All surface water samples were analyzed monthly for gross alpha and gross beta emitters, and gamma emitters. Quarterly composites were analyzed for tritium. Alpha concentrations were detected in 19 of the 48 indicator samples and in four of the twelve control samples, with concen-trations for all samples. ranging from 0. 7 to 12 pCi/L; LLD sensitivities which ranged from <0.6 to <4.7 pCi/L. Beta con-centrations for the indicator stations ranged from 2.4 to 130 pCi/L with an average of 51 pCi/L, and for the control statioti,

      '         from 7.5 to 81 pCi/L with an average of 45-pCi/L. *Nearly all of
     "*         the beta activity* was contributed by K-40, a natural component *

              *of salt and brackish waters, as illustrated in Figure 4, which compares averaged gross beta and K-40 concentrations.

Tritium ~onceritrations for the indicate~ statio~s ranged from 130 to 270 pCi/L. The average of the eight indicator samples with detectable *1.evels of tritium was 160 pCi/L. Tritium was detected in one of the four control samples at 150 pCi/L. Levels for the years 1973 through 1986 are plotted in Figure 5. Gamma spectrometric analysis of surface. water samples -showed detectable concentrations of K-40 in 34 of the 48 samples. The average K-40 concentration at the indicator stations was 88

pCi/L, .with a range of 33 to 160 pCi/L. Average K~4o concentra-tio~ at the control station, where detectable concentrations

             *_were found in nine of the twelve samples, was 70 pCi/L with a range of 29 to 95 pCi/L. Radium-226 was detected in seven indicator station samples, with the*values ranging from 2.6 to 11 pCi/L, and one control station sample at 25 pCi/L. Radium-226
          ,;

concentrations in this year's samples were higher than in _ j *_previous years due to procedural change in which water samples

           '    are no longer boiled down to a 100 ml standard geometry. This change results in less radon daughters being removed from the sample. Since Ra-226 is an alpha emitter, its identification by gamma isotopic.analysis is obtained by counting the Pb-214 daughter product. .concentrations of Th-232 in five indicator station samples were detected rangingfrom 5.3 to 9.3 pCi/L and one control sample at 9 .2 pCi/L.. LLD sensitivities for Th-232 ranged from <5.3 to <9.3 pCi/L.

Fish (Tables c~28, C~29) Edible species of *fish were collected semi-annually at thre.e locations and analyzed .for tritium and gamma .emitters (flesh~ and for sr-89 and sr-90 (bones). . Samples included channel catfis.hi, summer flounder, weakfish and bluefish. Gamma spectrometry of these samples indicated K-40 in all s.i~ samples at an average concentration of 3000 pCi/kg-wet with a range of 2700. to 3300 pCi/kg-wet. One of the six samples had detectable concentrations of Cs-137 with a value of 8.3 pCi/kg-wet. The LLD sensitivity for the other five samples

ranged from <12 to <19 pCi/kg~wet. Radium-226 was detected in the second semi-annual sample at two locations, at concentrations of 33 and 41 pCi/kg-wet. Levels as high as 130 pCi/kg-wet ~ere observed during the preoperational period [2]. Thorium-232 WJas detected in the ~irst semi-annual sample from the control station at a concentration of 29 pCi/kg~wet. LLD sensitivities for Th~232 ranged from <31 to <61 pCi/kg-wet. s~rontium-89 was detected in one of the six bone samples, with a concentration of 330 pCi/kg-dry. The LLD sensitivities for the other six samples ranged from <40 to <75 pCi/kg-dry. Two of the four semi-annual indicator samples analyzed for sr-90 had detect-able concentrations of 34 and 240 pCi/kg~dcyf with an average of 137 pCi/kg~dry. The level seen at the control location fo~ the sample collected during the period from May 12 to May l~, 1986 was 1500 pCi/kg-dry. ~ review of station effluent release records does not indicate any significant quantity of Sr-89 or sr-90 being discharged during the first half of the year [231. Tritium analyses were performed on the aqueous fraction of the flesh portions* of these samples. None of the samples analyzed indicated any detectable concentrations of tritium.

Ambient radiation le~els as measured .in our program were relatively low, averaging 5.1.mrad/std. month. Although ambient radiation levels remained normal, our surveil-* lance programs were sufficiently sensitive to detect radio-nuclides in the environment which were discharged from the damaged Chernobyl~4 reactor. The concentrations measured and provided in this report although higher than normal were not excessive. In fact, with the exception of I-131 in milk, none of the concentration found exceeded the reporting levels estab-lish~d by the USNRC. The reporting levels establlshed in the Technical Specifications applies only to abnormal environmental measurements caused by the licensed power reactor. None of the I-131 detected in milk was due to the o*peration of the Salem or Hope Creek reactors. The operation of SGS Units One and Two and HCGS had no significant effect on the radiological character-istics of the environs of Artificial Island.

APPENDIX B SAMPLE DESIGNATION.*: . The PSE&G Research.Corporation identifies samples by a three part code. The first two letters are the power station identification code, in this cas.e

       ' SA".

9 The next three letters are for tl'l.e media sampled. AIO = Air Iodine IDM = Immersion Dose (TLD) APT = Air Particulates MLI< = Milk ECH = Hard Shell Blue Crab PWR = Potal:lle Water (Raw) ESB = Benthic organisms PWT = Potable Water (Treated) ESF = EdilJle Fish

RWA = Rain Water ESS = Sediment SOL = Soil FPB = Beef SWA = surface Water FPL = Green Leafy Vegetacles VGT = Fodder crops (Various)

FPV = Vegetables (Various) WWA = Well Water GAM = Game The last four symbols are a location code based on direction and distance from the site. Of these, the first two represent each of tl'l.e sixteen angular sectors of 22.5 degrees centered about the reactor site. Sector one is divided evenly by the north axis and other sectors are numbered in a clock-w~e: directioru i.e. 2=NNEP 3=NE, 4=ENE~ etc;. The next digit . is a letter Q which represents the radial distance from the plant~

s = on-site location E = 4~5 Dci.les off-site A = 0~1 DU.les off-site F = 5-10 miles Off=site

              .B = l-2 miles off-site                G =   io~20 miles off-site c = 2~3 miles off-site                 H =   <20 miles off-site D = 3-4 miles off-site The last number is the station numerical designation within each sector and zone; e.g., l,2,3, *** For example, the designation SA-WWA-SDl would indi.cate a sampie in the SGS program (SA), consisting of well water (WWA), whi.ch had been collected in sector number 5, centered at 90' (due east) with respe<;t. to the reactor site at a radial distance of 3 to 4 miles off-site, (therefore, radial, distance* D). The number l indicates that this is sampling station #l in that particular sector *

SYNOPSIS OF:PSE&G-RESEARCH CORPORATION l?ROCEI;JURE GROSS ALPHA ANALYSIS OF WATE~ SAMPLES - The sample is thoroughly miXed. Then, a 250ml portion.of sample and an equal volume of deionized water blank are acidified with dilute sulfuric acid. Barium carrier is added and the sample heated to 50°C in order to help pre-cipitate barium sulfate. Maintaining the same temperature for the remainder of the procedure, iron carrier is then introduced. After a 30 minute equili-bration period, the sample is neutralized with dilute ammonium hydroxide to precipitate ferric hydroxide. The mixed precipitates are then-filtered onto a membrane filter, dried under -an infrared heat lamp, weighed and mounted on a stainless steel planchete The sample is then alpha-counted for lOO minutes on a low background gas proportional counter, along With a U-238 source of the same geometry. The blank is treated in the same manner as the sample. Water samples found to be excessively turbid due to the presence of suspended organic material require pretreatment of this material for the purpose of keeping the final sample thickness to a minimum. This is accomplished by filtering a measured aliquot of the sample (while the filtrate is set aside) and ashing the collected residue in a crucible. A blank of the same volume is handled in the same manner. Whatever leftover sample residue remains,after the ashing,is dissolved in concentrated nitric acid and passed through a hardened fast filter paper and combined with the sample- filtrate. The combined sampl is then neutralized with dilute ammonium hydr'oXide. From this point, both sample and-blank are acidified with dilute sulfuric acid. Barium carrier is added and the sample is heated to so 0 c in order to help.precipitate barium sulfate. Maintaining the same temperature for the remainder of the procedure, iron carrier is then introduced. After a 30 minute equilibration period, the sample is neutralized with dilute ammonium hydroXide to precipitate ferric hydroXide. The miXed precipitates are then filtered onto a membrane filter, dried under an infrared heat lamp, weighed and mounted.on a stainless steel planchet.

N. PROCEDURE

ANALYSIS OF WATER FOR .POTASSIUM 40 A 60 ml aliquot of water sample (with the exception of rain water) received by the Research and Testing Lal:loratory is first acidified to pH <2 With con-centrated nitric acid and then analyzed. for potassiwn by the following Atomic Absorption Spectrophotometry method: potassiwn standards of known concentra-tion (similar to that of the unknowns) are first prepared. An aliquot of each sample and standard is pipetted into stoppered flasks. In addition, a duplicate sample, ERA standard and blank water sample are likewise pipetted into their respective flasks. A solution consisting of 4% sodiwn is diluted 1:1 with water and then added to all the flasks. Depending on the AA instrument used, a calibration curve is prepared from the standards after which the samples are ~hen run. If the al:lsorbance of any sample is higher than the upper standard used, the sample is then either diluted and re-run, the burner head turned 90°, a more concentrated standard added to the calibration curve or a less sensitive wavelength used. Tne results, reported in parts per million (ppm), are converted to pCi/L by means of a computer program. Calculation of K-40 Activity: K-40 Activity (pCi/L) = 0.85*C 0.85 = Proportionality constant for converting ppm to pCi/L c = Potassium concentration, ppm ... ;

SYNOPSIS OF CONTROLS FOR ENVIRONMENTAL .POLLUT.ION, INC., PROCEDURE TRITIUM ANALYSIS OF AQUEOUS FRACTION OF BIOLOGICAL MATERIALS An aliqtlot of fish or cral:J flesh is placed in a round bottom flask, along with 200ml of benzene, and the water removed via azeotropic distillation. Three milliliters of the extracted water is then mixed with aquasol cocktail (NEF-934 Aquasol cocktail, manufactured by New England Nuclear corporation). The resultant miXture is comprised of 19 percent sample in a clear gel-type aquasol and provides a tritium counting efficiency of approXimately 30 percent, when counted on a Beckman r..s~100 Liquid Scintillation Spectrometer. The efficiency of the counting system is determined by placing 6 tritium standards (certified by NBS) before each set of water samples to be counted. The counting efficiency is determined from these standards which are equal in activity but vary in the amount of quenching. All samples are counted for 500 minutes each.

Teledyne Isotopes employs one of three possible data acquisition and computation systems. The first, a Data General NOVA mini-computer, in series with the pulse height analyzer, calculates* the number of

If no peak is observed, then only tne background is used (along with sample volume, collection date and length of count) to.determine the detection lilni.t. The activity or MDL of each nuclide is computed on an IBM 360. This semi-automatic system is in contrast with the other two data acquisition* and computation systems, namely, a Tracor Northern TN-11 and a Nuclear Data 6620, which perform all the above computations automatically.

SYNOPSIS OF PSE&G .RESEARCH CORPOBATION~-PROCEDURE . BADIOSTRONTIUM* .ANALYSIS OF AIR FILTERS The air filters are placed in a sma1l beaker and just enough fuming nitric acid is added to cover t~e filters. A blank, composed of the same number of clean air filters, is prepared in the same way. Stable strontium carrier is then introduced into each sample and several fuming nitric acid leachings are carried out to remove the radiostrontium from the filter media. once this is done, the resultant nitrates are dissolved in distilled water and the filter residue is filtered out. Radioactive interferences are stripped out by coprecipitation on ferric hydroXide (yttrium strip) followed by a barium chromate strip. The strontium* is precipitated as a carbonate, which is dried and weighed. The samples and b~ank are then counted on a low background gas proportional counter and, again, at least 14 days later. The basis for this two count method is-that sr-90 and sr-89 are both unknown quantities requiring two simultaneous equations to solve for them. . calculation of sr-90 Activity:

One part is put aside for gross alpha analysis. and the other part evaporated on a hotplate to a small volume. The sample is transferred to a centrifuge tu.be and fuming nitric acid added to form the strontium nitrate precipitate. After centrifuging and pouring off the supernate, the precipi=

tate is dissolved in deionized water and an iron scavenge performed. This marks the ~eginning of the Y~9o ingrowth period. centrifuging and discarding the precipitate, standardized yttr1Wl1 carrier is added to the supernate and the sample is set aside for 5 to 7 days. After this period, the sample is alkalinized with ammonium hydroXide and heated in a hot water oath to form

          *yttrium hydroxide. After cooling, the sample is centrifuged and the supernate saved for Sr-89 determination. The precipitate is dissolved with dilute nitric and hydrochloric acids, and the yttrium precipitated as oxalate using saturated ammonium oxalate solution. The yttrium oxalate is mounted on a .

tared paper filter, oven dried, weighed and counted on a gas proportional counter.

SYNOPSIS OF PSE&G. RESEARCH CORPORATION PROCEDURE *. RADIOSTRONTIUM ANALYSIS.OF*RAW MILK StalJle strontiwn carrier is first introduced into.a nti.lk sample and into a distilled water sample of equal volume to be used as a blank. The sample(s) and blank are passed through cation resin columns which adsorb strontium, calcium, magnesium and other cations. These cations are then e1uted off with a TRIS-buffered 4N sodi~ chloride solution into a beaker and precipitated as carbonates. The carbonates are converted to nitrates with 6N nitric acid and, by aqidifying further to an* overall concentration of 70% nitric acid, strontium is forced out of solution somewhat ahead of calcium. Barium chromate precipitation is then performed to remove any traces of radium and rad.iobarium.e Strontium recrystallization is carried out to remove residual calcium which may have been coprecipitated with the initial strontium precip~ itation. Another recrystallization removes ingrown Y=90, marking the time of the yttrium strip * . The strontiwn is precipitated as its carbonate, filtered, dried and weighe~ to determine strontium recovery. The samples and blank are then counted on a low background gas proportional. counter and, again, at least 14 days later. The basis for this two-count method is that sr-90 and sr-89 are both unknown quantities requiring two simultaneous equations to solve for them. caiculation of 0 Sr~9o Activity: Sr-90 Results (pCi/L) = N4/R (2o22)*(E)*(E(l5)/E 9 )~(S6)*(V)li(U) where SS =A + B*M + C*M2 (This is the qenera1 form of the norma1ized Sr-90 efficiency regression equation for one particular gas proportional counter, where A, Band care regression coefficients.)

SYNOPSIS OF P.SE&G RESEARCH' CORPORATION* *PROCEDURE_*:.:*;.... - RADIOSTBONTIUMANALYSIS OF WATER Stal:>le strontium carrier is introduced into a water sample and into a distilled water sample of the same volume which is used as a blank. The sample(s) and blank arethen made alkaline and heated to near boiling"before precipitating the carbonates. The carbonates are converted to nitrates by fuming nit~ic acid recrystallization which acts to purify the sample of most of the calcium. Radioactive interferences are stripped out by coprecipita-tion on ferric.hydroxide (yttrium strip) followed by a barilim chromate strip. The strontium is precipitated as a carbonate before being dried and weighed. The samples and blank are then counted on a low background gas proportional counter and, again, at least 14 days later. The basis for this two count. method is that sr-90 and sr-89 are both unknown quantities requiring two simultaneous equations to solve for them. Since surface waters , _as well as some drinking water samples , have bee*n found to contain significant amounts of siaJ:>le strontium, a separate aliquot from each sample is a.!alyzed for stal:>le strontium. These results are used in correcting the chemical recovery of strontium to its true value. Calculation of sr-90 Activity: Sr-90 Results (pCi/L) = N4/R (2.22)*(E)*(E(lS)/E')*(S6)*(V)*(U)

A blank con-taininq only 1/3 - liter concentrated HC~ and Sml strontiwn carrier is run in parallel with the sample. The samples are stirred viqorously for at least 30 minutes and then filtered. The filtrate is then diluted to a known volume and aliquots removed for stable str:ontiwn. The remaining sample is alka.linizeci with ammonium hydroXide to precipitate all the transitional elements. After filtering out these interferences, the filtrate is heated and sodium carbonate added to precipitate strontiwn and calciwn carbonate.

These carbonates are first filtered and then di.qested with 6N HN0 3

Subsequently, radi.oactive impurities are removed by two precipitation steps, using ferric hydroxide and bariwn chromate as carriers. The strontium is precipitated as strontium carbonate before beinq dried and weighed. The samples are counted for beta activity in a low background gas proportional counter (Count time will vary, depending on the desired sensitivity.). There is a second count at least 14 days later.

SYNOPSIS OF PSE&G RESEARCH CORPORATION.PROCEDURE ANALYSIS OF ENVIRONMENTAL SAMPLES FOR STA~LE STRO~TIUM It has been the practice of the Environmental Division to perform a stable strontium determination on any samples to be analyzed for strontium 90 and 89, i f they are likely* to contain significant amounts of the stable isotopes.. In the case of mineral (soil or sediment) or biological (bone and shell) media, an ashing and/or acid leaching is performed to extract the element{s) of interest. The removal of the aliquot is done early in the course of the radiostrontium analysis and involves the withdrawl of 25 ml of diluted leachate (soil and sediment only) from the regular sample, transferring it to a flask. Bone and shell are prepared by ash~ng 2 g of sample, digesting in 6N HCl, filtering out insoluble residues and then transferring to a flask. All, the above samples are analyzed by the method of Standard Additions, whereby each sample leachate is spiked with known concentrations of stable strontium. Absorbances for sample, spiked samples and blank are determined by Atomic Absorption Spectroscopy (AAS) and are then plotted graphically and the true concentration is then extrapolated. Chemical and ionization interferences are controlled by adding 1% or more of lanthanum as chloride to all samples to be analyzed. Stable strontium is then determined by AAS in the air-acetylene flame at the 460.7 run line. For analysis of water, a 60-ml aliquot of sample is removed, acidified to pH<2 with hydrochloric acid and analyzed by AAS as follows: A group of strontium standards (of similar concentration to: the unknowns) is prepared. Then, to 9 ml of each prepared sample'* blank and standard, is added 1 ml. of lanthanum oxide solution. These are ana,lyzed at 460.1* run by air"".'acetylene AAS, following the manufacturer's recommended instrument parameters. All. results (calculated as milligrams of strontium per liter) are then used to find the true chemical recovery of strontium based on both the amount of carrier added (only in the case of soil and sediment) and the quantity of strontium intrinsic to the sample.

SYNOPSIS OF TELEDYNE ISOTOPES PROCEDURE: *. ANALYSIS OF AIR PARTICULATE FILTERS FOR GAMMA . Ai.r particulate filters are analyzed for gamma using a lithium~drifted germanium detector interfaced with a 2048 channel pulse height analyzer calibr~ted at 1.0 Kev per channel. Teledyne Isotopes employs one of three possible data acquisition and computation systems. The first, a Data General NOVA minicomputer, in series with the pulse height anaJ.yzer, calculates the _number of counts (and a one standard deviation). in the peak region by performing a linearly-interpolated background subtraction. If no peak is observed, then only the background is used (along with sample volumep collec~ tion date and length of count) to determine the detection limit. The activity or MDL of each nuclide is computed on an IBM 360. This semi-automatic system is in contrast with the other two data acquisition and computation systems, namely, a Tracor Northern TN-ll and Nuclear Data 6620 which perform all the above computations automatically. All resultant spectra are stored on magnetic tape.

SYNOPSIS.OF PSE&G RESEARCH CORPORATION *PROCEDURE. GAMMA ANALYSIS OF SOLIDS several methods are employed in preparing solids for gamma anal.ysis, depending on the type of sample or sensitivity required. For high sensitivity anal.ysis of vegetation, meat and seafood, the sample is first weighed, then oven-dried to a constant weight. A ratio of wet-to-dry weight is computed before the sample is ground and compressed to unit density (lg/cm 3 ), whenever possible, in a tared al.uminum can. The can is weighed and then hermetical.l.y sea.l.ed and counted on a gamma detector. In most cases, a wet sample is prepared (assuming sensitivity can be met) by using a food processor to puree it. The sample is then poured into a cal.i-brated and tared clear plastic container until. a standard volume is reached. The sample is weighed and then seal.ad with a screw cap before gamma counting. Soil. and sediment samples are first oven dried until. a constant weight is achieved and then pul.verized. The sampl.e is added to a tared al.uminum can, compacted to a standard vol.lime and weighed. It is hermetical.l.y seal.ed and gamma counted. Benthic organisms are oven dried; followed by the physical. removal of any *

           *obvious impurities-(such as shells or twigs). The dried organisms are weigh and then wet-ashed with.concentrated nitric acid~ After al.l solids have been digested, the sample is evaporated to near drYt1ess and the residual. sal.ts taken up with distilled water. The sample is filtered and the filtrate added to an al.uminum can. The* sample volume is brought up to the standard geometry with distilled water and the can hermetical.ly sealed before gamma counting.

They are first annealed in a 2S0°C oven prior to exposure in the field. Following field exposure (for a 1-month or 3-month period) four separate areas of the dosimeter are read in a Teledyne Isotopes model 8300 TLD reader. The dosimeter is then re-irradiated by a standardized cs-137 source and the four areas are read again. Calculation of the environmental exposure is performed by computer, using the re-irradiation readings to determine the sensitivity of each area of the dosimeter. The readings of control dosimeters are sUbtracted to aJ.1ow for transit dose and system back-ground. The results are computed as follows: For. any given area of the dosimeter, the dose in mR is calculated by the following formula: DOSE = R * (REDOS~/RR)-AVC R = Initial reading of the area RR = Second reading of. the area (after re-irradiation) REDOSE = Re-irradiation dose, mR AVC =Average of control values, mR 4N where AVC = ~CDOSE/4H i=l H = Total number of control dosi-meters
