SUMMARY
This report summarizes the Shoreham Nuclear Power Station's (SNPS) Radiological Environmental Monitoring Program (REMP) operations for 1991. Throughout 1991, the plant remained in a defueled condition with all fuel rods removed from the reactor core and plant actMties in line with the anticipated license transfer to the Long Island Power Authority (LIPA).
Beginning 2 January 1991, strontium-89 and -90 analyses were discontinued after Safety Evaluations were conducted which allowed a reduction of REMf analyses to only those required by QDCM specifications.
In June 1991, after additional Safety Evaluations pertaining to the defueled condition were completed and the Offsite Dose Calculation Manual (ODCM) was revised, the following reductions were made in the REMP surveillance program: milk, potable (ground) water sampling and iodine-131 analysis v,ere discontinued. The outer thermoluminescent dosimeter (TLD) stations for direct radiation monitoring were also discontinued.
These reductions were made to recognize the fact that after the plant had been in the defecad mode for almost two yearsi, iodine-131 had long since decayed away and is no longer present onsite as a potential release source isotope. Potable water sampling was discontinued because plant liquid effluents are discharged directly into the Long Island Sound, which is being monitored by REMP and is not a source of potable or irrigation water.
The plant's non-operational status also eliminates the need for monitoring direct radiation at oiTsite TLD stations.
In July 1991, the Nuclear Regulatory Commission (NRC) granted LILCO a Possess;on Only Amendment to its previously obtained full power operating license for the Shoreham plant. This amended license, or the Possession Only License (POL), was implemented by LILCO in August 1991 and with it, all POL related changes in the Technical Speciflcations and the ODCM.
The objective of the SNPS REMP is to identify and measure plant related radioactivity in the environment and calculate the potential dose to the surrounding population. The operational phase, as well as the current non-operational, defueled phase, uses the preoperational baseline data to identify plant contributed radiation and evaluates the possible effects of radioactive plant effluents on the environment. The SNPS REMP is designed to comply with the plant's Technical Specifications, ODCM and NRC Regulatory Guides as described in licensing basis documents.
1 Defueling at Shoreham was completed on August 9.1989. All fuel was removed from the reactor vessel and stored in the Spent Fuel Storage Pool by that date.

l The REMP data is acquired by sampling various media in the environment which are then analyzed for any radiadon present. Media sampled within the aquatic environment in 1991 included surface water, fish, mvertebrates (sould, lobsters, etc.) and sediment. The atmospheric environment was samp'ed for airborne particulates throughout the year; and airborne iodine, milk, and potable s ater, during the first half of the year.
Starting June 1991, locally grown food products were sampled monthly during the growing season. Direct radiadon was measured using TLDs.
Radioactivity in environmental media varies from sample to sample as well as geographically; therefore, a number of sampling locations for each medium were selected using available meteorological, lar.d and water use data. Sampling locations are designated as either indicator or control locations. The indicator locations are placed close enough to Shoreham so that plant contributed radioactivity will be at its highest concentration. The r control sample locations are placed so that they will be beyond measurable influence of Shoreham and any other nuclear facility. An exception to this occurred at the onshore site for REMP location 13G2, at the entrance to Port Jefferson Harbor. During preoperational testing aquatic samples revealed the presence of low levels of lodine-131. An investigation revealed that the iodine-131 was from area hospitals treating patients for thyroid carcinoma. Thereafter, until 1990 a second onshore aquatic background location was sampled at the entrance to Mt. Sinal Harbor.
A number of radioactivity analyses were performed on each medium sampled. Not all samples underwent all types of radioanalyses; only those analyses appropriate for the particular medium sampled were performed.
The analyses included gamma spectrometry, iodine-131, tritium, gross beta radiation and direct radiation. lodine-131 analyses was discontinued after June 1991 under the revised ODCM requirements which reflect the plant's defueled, non-operating status.
Dose calculations for the SNPS environs were performed using concentrations of radioactivity detected in the samples collected. In all cases the calculated doses were similar to the background doses calculated for the previous years. Therefore, no environmental radioactivity was identified as having originated from SNPS.

-.m I. PROGRAM 4
THE PROGRAM The Shoreham Nuclear Power Station's (SNPS) Radiological Environmental Monitoring Program (REMP) is conducted in compliane, with NRC Regulatory Guide 4.15, licensing commitments, the Defueled Safety Analysis Report (DSAR) 11.6, SNPS Technical Specification Section 6.7.4.b. and SNPS Offsite Dose Calculation Manual (ODCM) Section 3/4.12.
The REMP was developed in general accordance with the NRC Radiological Assessment Branch Technical Position (BTP), Rev. 1, Nov. 1979, and findings in the Environmental Report (ER) 6. . 5. All samples were collected by personnel of the Long Island Lighting Company (Environmental Engineering Department) or biological contractors hired for the collection of aquatic samples. A synopsis of the sampling program can be found in Table 1. Maps and a description of sampling locations appear in Appendix B
During 1991 sample analyses were performed by Teledyne Isotopes of Westwood, New Jersey (referred to throughout the text as either "TI" or "the laboratory"), under contract to LILCO. A summary of analytical results appears in Appendix A and indMdual analysis results in Appendix C. Aquatic sample collections were performed by LILCO's Environmental Engineering Department and Energy & Environmental Analysts Inc. (EEA Inc.) under contract to LILCO.
A. Obiectives The objectives of the radiological environmental monitoring program are:
- 1. Identify and measure radiation and radioactivity in the plant emirons for the calculation of potential dose to the population.
- 2. Verify the effectiveness of in plant measures used for controlling Une release of radioactive materials.
- 3. Provide reasonable assurance that the predicted doses, based on efIluent data, have not been substantially underestimated and are consistent with applicable standards.
- 4. Comply with regulatory requirements. SNPS Technical Specifications and ODCM requirements, and provide records to document compliance.
l s
a Samole Collection
- 1. Aquatic Environment The aquatic environment at the SNPS site was examined by analyzing samples of surface water, fish, invertebrates, and sediment.
Surface water samples were taken at three locations in May and October using a Niskin bottle. The samples were placed in new polyethylene bottles following three rinses with the sample medium prior to collection. Samples of Bluefish (Pomatomus saltatrix), Winter Flounder (Pseu dopleuronectes americanu s), Windowpane (Scophthalmus aquos.ui), Sea Robin (Prionotus spp). Littje Skate (Raia erinaceal and Fluke (Paralichthys dentatusl were taken by trawl, '
sealed in plastic bags, frozen, and shipped to the laboratory for analysis.
Invertebrate samples of American Lobster (H o m a r u s americanus), Squid (Loligo Realejl) and Channeled Whelk (Busycon canaliculatal were collected by trawl. Channeled Whelk were also collected using pots. These invertebrate samples were sealed in plastic bags, frozen and shipped to the laboratory for analysis.
Beach sediment samples were also collected, scaled in plastic bags, frozen and shipped to the laboratory.
- 2. Atmospheric Environment The atmospheric environment was examined by analyzing airborne particulates collected on Gelman Type A/E filters using low volume air samplers (approximately 1 cfm). Airborne iodine was collected by absorption on triethylenediamine (TEDA) impregnated charcoal cartridges, manufactured by Scott, which were connected in series behind the airborne particulate filters. The samplers used were equipped with a vacuum recorder for sample volume correction to ensure sample -validity and to indicate any maintenance problems.
Should the sampler lose vacuum due to a leak the vacuum level reading will drop to zero. Since this may occur without a corresponding loss of electric supply the exact time of the maintenance problem will be g evident on the vacuum recorder chart.
Collection and analyses of airborne samples for idoine-131 were discontinued after June 25,1991 under ODCM Rev.17 to reflect the plant's .defueled condition. The last iodine air sample 'was collected for the week of June 18 - 25, 1991.
Sample volumes were measured using dry gas meters and corrected for differencca between the actual pressure seen by the 6
volume meter and the average atmospheric pressure. Sample volumes are corrected to standcrd pressure using average weekly barometric pressure (measured at LILCO's Environmental Engineering Department, Mehille) and air sampler vacuum readings. Time totalizers indicate the duration of time the sarnple was taken.
- 3. Terrestrial Ernironment The terrestrial environmtnt was examined by analyzing samples of milk and potable water during the first half of 1991, and of food products during the growing season (June to November) for the second half of the year.
When available, milk samples were collected from three locations monthly except dudng the pasture season in Mr: and June, when the sampling was increased to twice a month. % samples were shipped on ice with sodium bisulfite (NaHSO3) preservative added.
Potable water was collected during the first and the second quarters from three well locations. However, samples were unavailable from a fourth well,13S2, presumably due to a change in the water table.
Milk and potable water samplings were discontinued for the second half of 1991, when Revision 17 of the ODCM became effective.
This revision of ODCM reflects the plant's defueled, non-operating conditions. Milk samples were last collected on June 13 and potable -
water, June 6,1991.
- 4. Direct Radiation Direct radiation levels in the emirons were measured with energy compensated calcium sulfate (CaSO4:Dy) TLDs, each containing four separate readout areas. The TLDs are annealed by LILCO prior to placement in the fleid. After the quarterly collection, the TLDs are packaged and shipped to the laboratory for analysis along with a control dosimeter, and new ones are placed for the next quarterly period.
ODCM Revision 17 also reduced the TLD stations from 41 to 18.
This reduction took place after the second quarter TLDs were collected on July 11,1991. The 41 locations for the first two quarters included 4 that were added in 1989 at various area schools to better determine direct radiation levels at these sites. The present 18 locations include 16 onsite stations with one in each of the 16 meteorological sectors, plus two control locations at 11G1 and 12G1.

C Ouality Assurance
- 1. Teledyne isotopes Teledyne Isotopes has an extensive quality assurance program designed to ensure the precision and accuracy of the data generated.
An Interlaboratory Comparison Program is conducted with the Environmental Protection Agency (EPA). The results of the Program analyses are listed in Appendix E. Participation in this program permits estimation of bias in TI results from the deviation from the "known" value given, or by comparison with means of all participants.
The Tl Quality Assurance Program for Radiological Monitoring is described in various TI publications (References 15, 16, 17).
Approximately 10 percent of TI's total analytical effort is spent on quality control including process quality control, instrument quality control, intra and interlaboratory cross-check, and comprehensive data review. In addition, LILCO specifically requires that two percent of its analyses be duplicated for funher quality control cross check.
Additional information on the LILCO Quality Assurance Program is provided in NED 4170004, Quality Assurance Program for Radio-logical Environmental Monitoring Program. Shoreham Nuclear Power Station.
D. Data Interoretation
- 1. General The analytical data generated during 1991 were routinely evaluated by the TI project leader who served as liaison with Long Island Lighting Company's Environmental and Nuclear Engineering Departments. Several factors are important in the interpretation of the data. These factors are discussed here to avoid repetition in sections that follow.
Within the data tables (Appendix C) an approximate 95 percent
( 2 sigma) confldence interval is supplied for those data points above the lower limit of detection (LLD). These intervals represent the range of values into which 95 percent of repeated analyses of the same sample would fall. Tables C-13 and C-14 present typical and required LLDs, respectively.
Results for each type of sample were grouped according to the analysis pc.rformed. Means and standard deviations of these rcsults are calculated when applicable. The calculated standard deviations of grouped data represent sample rather than analytical variability. For 8
these eniculations any values below LLD are considered to be at the LLD As a result, the means are biased high and the standard deviations are biased low. When a group of data is composed of LLD values, averages are not calculated.
Grab sampling is a useful and acceptable procedure for taking environmental samples of a medium in which the concentration of radionuclides is expected to vary minimally with 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 that specific location and instant of time. As a result. variation of radionuclide concentrations in the samples will normally occur. Since these variations will tend to coanterbalance one another, the extraction of averages based upon repetitive grab samples is valid.
- 2. Gamma Isotopic Analyses SNPS ODCM Table 3.12.1-1 requires that analyses be performed on all media for gamma emitting radionuclides which may be attributable to efiluents from the plant. These analyses are in addition to requirements for specific gamma emitters such as 1-131 Cs-134 Cs-137, Ba-140, Mn-54, Fe-59, Co-58, Co-60, Zn-65, Zr-95 and Nb-
- 95. Industry experience suggests that these are the most likely radionuclides to find their way into the environment from a BWR nuclear power plant. Gamma spectroscopy is expected to identify most other nuclides which may be discharged when the LLDs for specified gamma emitters are met by this technique.
Tables 3.1 and 3.2 of the Shoreham Final Environmental Statement list the calculated liquid and gaseous effluents by -
radionuclide in curies per year. These release rates assume normal operation of the plant, including anticipated operational occurrences.
Those nuclides listed in Tables 3.1 and 3.2 which are not routinely observable by gamma spectroscopy and which are not specifically analyzed in other ways fall into two categories:
- 1. Those radionuclides with half-lives on the order of hours or minutes which cannot accumulate appreciably in the en -ironment (Na-24, Cu-64, Zn-69m, Zn-69 Sr-91, Y-91m, Y-92, Y-93, Tc-99m, Rh-103m, Rh-105, Rh-106, Te-129. Te-131m, Te-131,1-132, I-135, Ba-137m, Pr-143, Ce-143. Pr-144 and W-187).
- 2. Those radionuclides with no gammas (P-32, Fe-55), those with a trivial percentage of their transitions going by gamma emissions (Y-91), or those with their primary gamma 9
occurring at such a low energy and at such low abundance that it is not routinaly observable in the presence of other gamma activity (Nd-147). With only 10 pCi of Nd-147 calculated to be released per year in Shoreham's liquid effluents, the nuelide cannot be an important contributor to dose.
E. Dose Assessment The methodology for determining doses is similar for all pathways. Laboratory analyses from the REMP for each sample type are compiled. Data from all locations taken on the same date are averaged to obtain the most reliable approximation of the radioactivity concentration on that date for that sample type. The averages of all dates are then taken to provide the best approximation of radioactMty concentrations for the year.
When an average value has been obtained which represents a sample medium or an exposure pathway, it can then be used to calculate the dose for the year. Additional information, such as the quantity of fish, milk, v getables, etc., consumed per year by the maximum exposed individual is also needed to calculate the total dose (Reference 13).
The dose dt e to direct radiation exposure is monitored by TLDs.
The laboratory results for TLDs are expressed in dos,e units directly and do not require any additional calculations.
The dose to the total body or to a specific organ is then calculated by the product of the radionuclide specific dose conversion factor for its applicable exposure pathway, the environmental sample radionuclide concentration, and the ingestion or inhalation rate of the sample or medium of interest. For example, the following genial equation expresses this principle:
Dose = Concentration X Quantity ingested X Dose factor (mF m/yr) per sample per year The sample concentration is typically expressed in pCi/l or pCi/kg. For the ingestion pathway, the quantity ingested or consumed per year is expressed in kg/ year or 1/ year. Finally, the dose conversion factor is expressed in terms of mrem /pCi ingested or inhaled.

RESULTS AND DISCUSSION The analytical results for the reporting period of January 1 through December 31, 1991, have been divided into four categories: aquatic, atmospheric, terrestrial, and direct radiation. The individual samples and analyses within each category display the unique radiological characterisucs of that type of environment. Strontium 89 and -90 analyses were discontinued on January 1, 1991, ieducing the REMP to ODCM requirements. In June 1991 due to a program change, several additional sampling and analyses were discontinued. Analytical results of the REMP l are summarized in Appendix A. The data for individual analyses are presented in Appendix C.
A Acuatic Environment The aquatic environment in the vicinity of SNPS consists primarily of Long Island Sound. The radiological characteristics were studied by analyzing samples of surface water, Winter Flounder, Windowpane, Sea Robin, Bluefish, Little Skate, Fluke. American Lobster, Squid, Channeled Whelk. e.n d sediment. The samples were collected by LILCO's Environmental Engineering Department and Energy & Environmental Analysts Inc. (EEA Inc.) under contract to LILCO.
- 1. Surface Water (Table C-1)
Semiannual surface water samples were taken at three locations and were analyzed for tritium, gamma emitters, and lodine-131.
There was no detectable tritium in any surface water sample. This compares consistently with the 1990 tritium results, which were also all below the detection limit.
Naturally occurring potassium-40 was measured in all six semiannual samples over three locauons with an average of 188 pCl/l and a range between 143 and 235 pCi/1, as compared with 1990's average of 289 pCl/l and a range between 232 and 354 pC1/l. No other gamma activity above the detectable levels was measured in the six surface water samples as analyzed by gamma spectroscopy.
The May surface water samples were also analyzed for lodine-131.
Iodine-131 was not observed within the limits of detection.
- 2. Fish (Table C-2)
Thirty-three fish samples were collected at three locations and the edible portions analyzed for gamma emitters. Gamma spectrometry showed
< potassium-40 pn tent in all samples with an average concentration of 3451 15
pCi/kg wet and a range between 1540 to 4940 pC1/kg wet, comparing with 1990's average of 4242 pCi/kg wet and a range between 1990 and 10900 pCi/kg wet. Cesium-137 was not detected in any samples. This favors well with the detection of cesium-137 in three fish samples during 1990.
- 3. Invertebrates (Table C-3)
Nineteen invertebrate samples, comprised of lobsters, squid, and whelk, were collected at three locations and analyzed for gamma emitters.
Gamma spectrometry showed detectable levels of potassium-40 in all samples, ranging from 1380 to 7980 pCl/kg wet with an average acthity of 3176 pC1/kg wet. Thorium-228 was measured in one lobster sample with an aethity of 117 poi /kg wet. These compare to 1990's average potassium-40 activity of 3171 pC1/kg wet and an average of cesium-137 activity of 33.8 pCi/kg wet out of two samples of lobsters.
- 4. Sediment (Table C-4)
Two beach sediment samples were collected and analyzed for gamma emitt.ers. Both samples had measurable activities of naturally occurring potassium-40 with an average activity of 2350 pCl/kg dry and a range of 2090 to 2610 pCi/kg dry. Thorium 228 was measured in both samples with an average acuvity of 164 pCl/kg dry and a range of 141 to 186 pC1/kg dry.
All other gamma emitters were below the lower IJmits of detection.
Bt Atmospheric Emironment The atmospheric emironment in the vicinity of the SNPS was examined by analyzing samples of airborne particulates and airborne iodine at five sampling locations. TEDA-impregnated charcoal cartridges used to collect airborne iodine were collected weekly until June 25,1991 when this analysis was discontinued. 'Diey were analyzed by gamma spectrometry for iodine 131. Airborne particulate filters were collected weekly and analyzed for beta emitters. Quarterly composites from each station were analyzed for gamma emitters.
- 1. Airborne Particulates (Tables C-5, C-6, and C-7)
Beta-emitter concentrations ranged from 0.004 to 0.035 pC1/m3 with an annual average for the five sampling locadons of 0.016 pCi/m3 (Table C-5). Of the 264 measurements five were below the detection limit, nominally 0.003 pC1/m3 Figure 1 shows the average weekly gross beta fluctuations in airborne particulates from all stations for 1991. Figure 2 represents the average monthly gross beta results in airborne particulates from January 1,1977 through December 31,1991.

Results of gamma spectrometry (Table C 6) showed detectable levels of naturally occurring beryllium 7 in all twenty samples. The average beryllium 7 acuvity in the quanerly analyses was 0.073 pCf/m3 with a range i of 0.041 to 0.117 pC1/m3 Naturally occurring potassium 40 was not !
observed. All other gamma emitters were below the lower limit of l detectica. l l
- 2. Airborne lodine (Table C 7) i Analytical results of the 125 weekly atrborns iodine-131 samples were all below the lower limit of detecuon, with a range of results between
<0.008 and <0.06 pCl/m3, C. Terrestrial Emtronment The terrestrial environment in the vicinity of the SNPS was examined by analyzing samples of milk and potable water during the first half of the year, and food products during the remainder of the year. Gamma spectrometry was performed on all samples. In addition, lodine-131 analyses were performed on the milk samples, while tridum and lodine-131 analyses were performed on the potable water samples.
- 1. Milk (Tables C-8 and C 9)
All of the 24 monthly and seminionthly cow and goat milk samples analyzed for lodine 131 were below the LLD with sample results ranged between <0.1 knd <0.3 pCi/1. Naturally occurring potassium-40 was observed in all the milk samples, ne goat milk samples had an average measurement of 1578 pCl/l and a range of 1280 to 1900 pC1/l. ne cow milk samples had an average concentradon of 926 pCl/l with a rar.ge of 775 to 1140 pC1/l. Cesium-137 was detected in one of the 14 goat milk samplee. with an activity of 6.88 pCl/1. Nine of the 10 cow milk samples at Control Iecation 8G2 had detectable measurements of cesium-137 with an average of 10.5 pCi/l and a range of 6.31 to 14.2 pCl/1. All other gamma '
emitters were below the lower limits of detecdon.
- 2. Potable Water (Table C-10)
Five potable water samples were collected at three locations during 1991. All tritium results were below the lower limit of detecdon
- (100 pC1/l). No iodine-131 was measured above the lower limit of detection which were all <0.1 pCi/1. All other gamma emitters were below the lower limits of detection.

- 3. Food Products (Table C-II)
Forty two fruit and vegetable food products grown locally were ,
collected and analyzed, including tomatoes, potatoes, cabbage, fettuce. I carrots, peaches, strawberries, and corn. All samples contained naturally I occurring potassium 40 with an average of 2786 pCi/kg wet and a range of 1190 to 4880 pCi/kg wet. Also naturally occurring beryllium 7 was observed i in one sample of lettuce with a concentration of 131 pCl/kg wet. All other gamma emitters were below the lower limits of detection. The samples were also analyzed for iodine 131 by a radiochemical procedure. No activity was found. he detection limit varied from 3 to 100 pC1/kg wet.
D. Direct Radiation frable C-121 Direct radiation measurements were taken quarterly at 41 locadons during the first two quarters of 1991 and 18 locations during the last two quarters of 1991, using CaSO4:Dy thermoluminescent dosimeters (TLDs). TLDs were used to detect radiation levels near ground level in the vicinity of the Shoreham site due to terrestrial and cosmic gamma ray '
emitters and possible SNPS contributed direct radiation. Figure 3 presents a comparison of average TLD results from 1977 to 1991.
All TLD results presented in this report have been normalized to a standard month (30.4 days) to eliminate the apparent differences caused by the variations in exposure period. The average of the quarterly exposures of all 41 locations was 3.5 mR/ standard month. This is less than quarterly values, respectJvely, measured during the preoperational years 1983 and 1984. ,
Annual average results of all quarters at the same locations, as well as of all locatjons for each quarter, are given in Table C-12 with 95%
confidence limits for the mean value, except for the average of all locations and all quarters. For this last value, the 95% limits about any individual measurement, i.e., iO.9 mR/std. month, is given. He 95% limits for the mean of all locations and all quarters (N=118) are t0.08 mR/std. month about the sample mean of 3.6 mR/std. month for 1991.
E. Dose Assessment Initially, all positive concentrations of radionuclides in indicator samples, as shown in Appendix A. were considered for inclusion in the dose calculation, in an attempt to factor out as much of the contribution due to natural and man made background radiation as possible, indicator and control sample results were compared. If the control location results were 18
l l
greater than those at the indicator locadon, the indicator sample results were not included in the dose assessment.
Surface water from Long Island Sound was not considered as a significant human exposure pathway and therefore, not considered in the dose assessment. The dose due to standing on soll/ sediment was not calculated since this is accounted for in the direct radiation dose. Also, potable water was excluded from dose calculations because it is not considered a pathway. (Since ground water drainage is to the north into l the Sound, no water sources for drinking or irrigadon can be affected.) in l 1991, no radionuclide in the an:tlysis category was detected above the lower limits of detection in any of the potable water samples.
Bery111um-7, potassium-40, radium 226, radium 228 and thorium-228 are all naturally occurring isotopes and not likely to be produced as a result of the operation of Shoreham, so they were excluded. The remaining postuve isotope, cesium-137, was found in the milk samples. However, since the sample average at the control location (8G2), 10.5 pC1/l, is higher than that at the indicator locations (13B1 and 817) which is 6.88 pC1/l, it is also excused. The milk produced in the vicinity of Shoreham that was monitored under REMP has not been a source of commercial supply and is of limited quantity. It should be noted that cesium-137 exists in the Shoreham emtronment as a result of atmospheric weapons testing and the Chernobyl accident, Comparison of erwironmental concentrations found in 1991 shows that they are consistent with those of 1983. For 1991, therefore, there is no discernible dose components other than those from natural sources in the environment.

III. CONCLUSIONS 25
CONCLUSIONS The unit was defueled in August 1989, and has subsequendy been in a non operating condluon.
Analyses of environmental samples show results consistent wid1 those found during the preoperational years of 1983 and 1984. In addition, comparison of results reveals litde difference between indicator and control locations. Therefore, no isotopes could be idenUDed as having originated from SNPS.
Sensitive indicators revealed minute quanuties of radioactive fallout from the October 1980 atmospheric nuclear weapons test by the Peoples Republic of China and the Chernobyl accident in addition to radioactivity remaining from two decades of atmospheric testing.
Aside from these anomalies in the environment, expected normal .'
background radioactivity has been measured in REMP samples. Aquade and terrestrial samples were analyzed and reDected the normal background radiation found in the environment. The atmospheric environment was sampled for airborne particulates and-Figure 1 shows weeldy gross beta results in airborne particulates from January through December 1991.
Figure 2 shows the average monthly gross beta results in airborne particulates from February 1977 to December 1991. Direct radiation levels were relatively low and approximately the same at all locations. Figure 3 shows the average quarterly TLD resGis in mR/ standard month from January 1977 to December 1991.

APPENDIX B Sample Designation LILCO's Radiological Environmental Monitoring Program (REMP) identifies samples by a three part code. The first two letters are the power station identification code, in this c1se "SN". The next three letters are .or the media sampled.
SWA = Sudace Water (Long Island Sound) MLK = Milk AQF = Fish (1) GMK = Goat Milk AQ1 = Invertebrates (1) PWA = Potable Water (ground water)
AQS = Sediment FPV = Food Products (1)
APT = Airborne Particulates FPF = Fruit
^10 = Airborne lodine IDM = 1mmersion Dose (TLD)
The last four symbols are a location code based on direction and distance from the si.e. Of these, the first two represent each of the sixteen angular sectors of 22 1/2 degrees centered about the reactor site. Sector one is divided evenly by the north axis, and other sectors are numbered in a clockwise direcuon. i.e., 2=NNE, 3=NE, 4=ENE, etc. The next digit is a letter which represents the radial distance from the plant:
S = On site location E = 4-5 miles off site A = 01 miles off site F = 5-10 miles off she B = 1-2 miles off site G = 10-20 miles off site C = 2-3 miles off site H = >20 miles off site D = 3-4 rniles off site The last number is the location numerical designadon within each sector and zone, e.g.,1,2,3,.....for example, the designadon SN-SWA-3C1 would indicate a sample in the SNPS program SN, consisting of sudace water SWA, which had been mllected in the 22-1/2 degree sector centered on the northeast axis (3) between tne site boundary and 2-3 miles off site (C). The number 1 indicates that this is sampling station No.1 in the designated area.
Sampling locauons All sampling locations and specific informadon about the indWidual locadons are given in Table B-1. Tables B-2 through B-5 list the sampling locadons and media required by Technical Specifications.
(1) A more specific means of classificadon will be noted in the comment secuon of each laboratory report for these samples. For example, AQI will be designated, in the sample description, as aquauc invertebrate. However, the comment section will specify the sample type by the generally accepted common name of the sample involved. In this case, clam, lobster, crab or other aquatic invertebrate would be listed in the comment section.

r Maps B-1, B-2 and B 3 show the locations of 1991 sampling stations with respect to the site. These maps are tracings of portions o rlarger maps prepared by LILCO's Survey Division after an extensive land survey of REMP monitoring locations.
Additional information can be obtained by referring to the Site and Vicinity Map of the Shoreham Nuclear Power Station (Map B-2), the map of Long Island ana Connecticut Shore (Map B-3) and by contacting either LILCO's Environmental Engineering Department or Survey Division. Tables B-1 through B-4 include the locations and sample types which were discontinued in the second half of 1991. In Table B-5, they are marked and footnoted as such.

DETERMINATION OF GROSS BETA ACTIVITT IN WATER SAMPLES 1.0 JNTRODUCTION
, 'the procedures described in this secuon are used to measure the overall radioacthity of water samples without identifying the radioactive species present. No chemical separation techniques are involved.
One liter of the sample is evaporated on a hot plate. A smaller volume may be used if the sample has a significant salt content as measured by a conductivity meter. If requested by the customer, the >
sample is filtered through No. 54 filter paper before evaporation, removing particles greater than 30 microns in size.
After evaporating to a small volume in a beaker, the sample is rinsed into a 2 inch diameter stainless steel planchet which is stamped with a -
concentric ring pattern to distribute residue evenly. Final evaporation to dryness takes place ender heat lamps.
Residue mass is determined by weighing the planchet before and after mounting th3 sample. The planchet is counted for beta activity on an automatic proportirmal counter. Results are calculated using empirical self-absorption curves which allow for the change in effective counting efficiency caused by the residue mass.
70
2.0 DETECTION CAPABILTQ' Detection capability depends upon the sample volume actually represented on the planchet, the background and the efilciency of the counting instrument, and upon self-absorpuon of bete parucles by the mounted sample. Because the radioactive species are not identifled, no decay corrections are made and the reported activity refers to the counung time.
The minimum detectable level (MDL) for water samples is nominally 1.6 picoeuries per liter for gross beta at the 4.66 sigma level (1.0 pC1/1 at the 2.83 sigma level), assuming that I liter of sample is used and that h gram of sample residue is mounted on the planchet. These figures are based upon a counting time of 50 minutes and upon representative values of counting efficiency and background of 0.2 and 1.2 cpm, respectively.
The MDL becomes significantly lower as the mount weight decreases because of reduced self absorption. At a zero mount weight, the 4.66 sigma MDL for gross beta is 0.9 picoeuries per liter, These values reflect a beta counting efficiency of 0.38.
71 i'
I GROSS BETA ANALYSIS OF SAMPLES Airborne Partfculates After a delay of five or more days, allowing for the radon 222 and radon 220 (thoron) daughter products to decay, the filters are counted in a gas flow proportional counter. An unused air particulate filter, supplied by LILCO, is counted as the blank.
Calculatfor.w of the results, the two sigma error and the lower limit of detection (LLD):
RESULT (pC1/m3) = ((S/T) - (B/t))/(2.22 V E)
TWO SIGMA ERROR (pCi/m3) = 2((S/T2 ) + fB/t 2))1/2 (2.22
/ V E) ,
LLD (pC1/m3) = 4.66 (B1/2)/(2.22 V E t) where:
S = Gross counts of sample including blank B = Counts of blank E = Counting efficiency T = Number of minutes sample yas counted t = Number of minutes blank was counted V = Sample aliquot size (cubic meters) 72
1 ANALYSIS OF SAMPLES FOR TRITIUM Water Approximately 2 ml of water are converted to hydrogen by passing the water, heated to its vapor state, over a granular zinc conversion column heated to 400* C. The hydrogen is loaded into a one liter proportional detector and the volume is detennined by recording the pressure.
The proportional detector is passively shielded by lead and steel and
- an electronic, anticoincidence system provides additional shielding from cosmic rays.

ANALYSIS OF SAMPLES FOR IODINE-131 Milk or Water Two liters of sample are first equilibrated with stable lodide carrier. A batch treatment with anion exchange resin is used to remove iodine from the sample. The iodine is then stripped from the resin with sodium hypochlorite solution, reduced with hydroxylamine hydrochloride and extracted into carbon tetrachloride as free iodine. it is then back extracted as lodide into sodium bisulfite solutjon and is precipitated as palladium todide. The precipitate is weighed for chemical yield and is mounted on a nylon planchet for low level beta counting. The chemical yield is corrected by measuring the stable iodide content of the milk or the water with a specific ton electrode.
Calculations of results, two sigma error and the lower limit of detection (LLD) in pC1/l:
RESULT = (N/ot-B)/(2.22 E V Y DF)
TWO SIGMA ERROR = 2((N/At+B)/At)I/2(2.22 E V Y DF)

l GAMMA SPECTROMETRY OF SAMPLES Milk and Water A 1.0 liter Madnelli beaker is 1111ed with a representative aliquot of the i sam ale, ne sample is then counted for approximatcly 1000 minutes with a shle:ded Ge(LI) detector coupled to a mini computer based data acquisition system which performs pulse height analysis.
Dried Solids Odier Than Soils and Sediments A large quantity of the sample is dried at a low temperature, less than 100'C. As much as possible (up to the total sample) is loaded into a tared 1-liter Marinelli and weighed, ne sample is then counted for approvJmately 1000 minutes with a shielded Ge(L1) detector coupled to a mini computer-based data acquisition system which performs pulse height analysis.
HEh As much as possible (up to the total sample) of the edible portion of the sample is loaded into a tared Marinelli and weighed. The sample is then counted for approximately 1000 minutes with a shielded Ge(LI) detector coupled to a mini-computer-based data acquisition system which performs pulse height analysis.
Soils and Sediments Soils and sediments are dried at a low temperature, less than 100'C.
The soll or sediment is loaded fully into a tared, standard 300 cc container and weighed. The sample is then counted for approximately six hours with a shielded Ge(L1) detector coupled to a mini-computer-based data acquisition system which performs pulse height and analysis.
Charcoal Cartridces (Air lodine)
Charcoal cartridges are counted up to five at a time, with one positioned on the face of a Ge(LI) detector and up to four on the side of the Ge(LI) detector. Each Ge(L1) detector is calibrated for both ;30sitions. The detection limit for I 131 of each charcoal cartridge can ac determined (assuming no positive 1-131) uniquely from the volume of air which passed through it. In the event I-131 is observed in the initial counting of a set, each charcoal cartridge is then counted separately, positioned on the face of the detector.

Airborne Particulates i
l The thirteen airborne particulate filters for a quarterly composite for each field station are aligned one in front of another and then counted for at least six hours with a shielded Ge!L1) detector coupled to a mini-computer-based data acquisition system which performs pulse height analysis.
A mini computer software program defines peaks by certain changes in the slope of the spectrum. The program also compares the energy of each peak with a library of peaks for isotope identification and then performs the radioactivity calculation using the appropriate fractional gamma ray abundance, half life, detector efficiency, and net counts in the peak region. The calculation of results, two sigma error and the lower limit of detection (LLD) in pCl/ volume of pCi/ mass:
RESULT = (S-D)/2.22 t E V F DF)
TWO SIGMA ERROR = 2(S+B) /2 /(2.22 t E V F DF)
LLD = 4.6G(B)l/2 /(2.22 t E V F DF) where: S = Area, in counts, of sample peak and background (region of spectrum of interest)
B = Background area, in counts, under sample peak, determined by a linear interpolation of the representative backgrounds on either side of the peak t = length of time in minutes the sample was counted 2.22 = dpm/pCi E = detector efficiency for energy of interest and geometry of sample V = sample aliquot size (liters, cubic meters, kilograms, or grams)
F = fractional gamma abundance (specific for each etaitted gamma)
DF = decay factor from the mid-collection date to the counting date 76
ENVIRONMENTAL DOSIMETRY l
Teledyne isotopes uses a CaSO 4 :Dy thermoluminescent dostmeter (TLD) which the company manufactures. This material has a high light output, negligible thermally induced signal loss (fading), and negligible self dosing. The energy response curve (as well as all other features) satisfies i NRC Reg. Guide 4.13. Transit doses se accounted for by use of separate TLDs.
Following the field exposure period the TLDs are placed in a Tcledyne Isotopes Model 8300. One fourth of the rectangular TLD is heated at a time and the measured light emission (luminescence) is recorded. The TLD is then annealed and expered to a known Cs-137 dose; each area is then read again. This provides a calibration of each area of each TLD after every field use. The transit controls are read in the same manner.

(a) EPA Results - Expected laboratory precision (1 sigma). Units are pCi/ liter for water and milk except K is in mg/ liter. Units are total pCi for air paruculate f11ters.
(b) Teledyne Results - Average t one sigma. Units are pCl/ liter for water and milk, except K is in mg/ liter. Units are total pCi for air particulate filters.
(c) The sample presents a different counting geometry. The EPA deposits activity ir4 a 3/4 inch diameter circle, on a plastic disk approximately 3/32 inch thick. A special calibration for EPA filters will be performed. The laboratory has obtained blank filters from the Las Vegas facility, and will simulate their deposits. (Note: Gross alpha measurement is not required under the SNPS REMP, but is part of EPA's program requirement.)
(d) The lowest three results out of nine analyses were chosen. Other results in the group were close to the given value. Subsequent EPA analyses were accepted without selection, leading to acceptable results. (Note:
Ra-228 to a naturally occurring radioisotope and is not attributable to SNPS.)
(e) The cause for the deviation is believed to be erroneously high strontium yields, probably caused by incomplete separation of calcium. The laboratory has investigated carrier concentrations and pipeting techniques, and have found them to be correct. Further aspects of analysts' techniques are being tested. De laboratory has received a new strontium extraction material developed at Argonne Nauonal Laboratory.
Experiments with this method to achieve better separatJon of calcium were completed and procedure PRO-03R 105 was implemented on 2/1/92. (Note: Sr-89 analysis was not requird for SNPS milk samples in 1991, but is part of EPA's program requirement.)
(f) There is no apparent cause for the low K-40 results. Two other isotopes spiked in the sample were in good agreement with EPA v71ues. Unit conversions were reviewed and found to be correctly applied. Possible background errors in geometty were investigated and found to have an insignificant effect. (Note: Sr-90 analysis and gress alpha meaprement were not required under the SNPS REMP in 1991, but is part of EPA's program requirement.)
(g) Probable failure to transfer all sample residue to the counting plarxhet.
Analysts are being tested using in-house and other EPA spikes. ! Note:
Gross alpha measurement is not required under the SNPS REMP, but is part of EPA's program requirement.)

[.
SNPS LAND USE CENSUS The Land Use Census program complies with Section 3/4.12.2 of SNPS ODCM. This requires a survey of all milk animals and gardens greater than 50m2 (500 ft2) producing broad leaf vegetation within a radial distance of 8 Km (5 miles). LILCO is also required to identify the nearest milk animal, residence and garden in each of the 16 meteorological sectors.
Environmental Engineering Department conducted the 1991 dairy animal census, during April through July, This survey was conducted by Environmental Technicians driving through each neighborhood within the 5 mile radial distance and visually checking for dairy animals. When a dairy animal was observed the technicians requested information from the owner concerning the amount of milk produced, feed, number of animals and grazing methods.
The 1991 census results indicated that there are no milk. producing cows within a 5 mile radial distance from the site: however, the survey did locate the following milk producing goats:
- 1. Sector 13,1.9 miles west of SNPS Poole Briarcliff Road Shoreham, New York 11786 REMP Monitoring Location 13B1 Inventory: 1 milking goat I non milking goat Inventory Date: April 18,1991
- 2. Sector 11, 2.40 miles southwest of SNPS Shoreham-Wading River School District Middle School Randall Road Shareham, New York 11786 REMP Monitoring Location 11C1 (Milk not being sampled due to owners decision not to participate).
Inventory: 2 milking goats O non-milking goat Inventory Date: April 18,1991 112
Table G-1 lists the nearest milk animal in the sixteen meteorological sectors. Additional field survey data are filed in the Shoreham Record Retrieval System. l l
The Garden Census was also conducted by Environmental Engineering Technicians visually noting each garden of 50m2 (500 ft2 ) or greater. The 1991 census was performed during July, August, and September locating a total of 206 gardens. Table G-2 lists the nearest garden in the sixteen meteorological sectors. The field survey sheets and maps are filed at Environmental Engineering MeNille and in the Shoreham Record Retrieval System.
Environmental Engineering identifles nearest residences by utilizing both aerial photography and visual confirmation. This year's census was conducted in November and December. Table G-3 lists the nearest residence in each meteorological sector.
