SUMMARY

Since April 1972 Radiation Management Corporation (RMC) has conducted the Pre-operational Radiological Environmental Monitoring Program (REMP) for Pennsyl vania Power and Light Company (PP8L) at the Susquehanna Steam Electric Station (SES).

This report presents the analytical results for samples taken during 1980. A total of 2175 analyses including direct radiation, surface water, well water, potable water, sediment, air particulates, air iodine, precipitation, milk, fish, food products, meat, game, vegetation and pasture grass were collected in 1980.

A variety of radionuclides, both naturally occurring and man-made, were detec-.

ted in the environs of the Susquehanna SES. Naturally occurring radionuclides were found at levels expected for that environment. The man-made radionuclides found, primarily in air particulates, precipitation and pasture grass, were the fission products typically found in nuclear weapons test fallout. In particular, fallout from the atmospheric nuclear weapons test by the People's Republic of China on October 15 was observed in samples collected during November and December. The detection of this event indicates that the Susquehanna SES REMP is sensitive to fluctuations in the radiological characteristics of the environment around Susque-hanna SES.

INTRODUCTION INTRODUCTION The Susquehanna SES will contain 2 BWR generating units, each with a capacity of about 1050 MWe. Units 81 and 82 are scheduled for initial criticality in 1982 and 1983, respectively. This site is located on a 1075 acre tract along the Susque-hanna River, five miles northeast of Berwick in Salem Township, Luzerne County, Pennsylvania.

The area surrounding the site can generally be characterized as rural, with forest and agricultural lands predominating. More specific information on the dem-ography, hydrology, meteorology and land use characteristics of the local area may be found in the Environmental Report(l), the Safety Analysis Report(2) and the Draft Environmental Statement - O,L. (3) for Susquehanna SES.

RMC has previously reported results for the preoperational radiological environ-mental monitoring program (REMP) from 1972-1979 (4-11); the present document continues the series with coverage for 1980. It presents in detail the type and number of sam-ples collected, the analyses performed and the data generated.

PROGRAM I

I

,I PROGRAM The preoperational REMP continued in 1980 and will continue unti1 initial critica-lity of Unit 91. At that time the operational phase of the program will be instituted and continue thereafter. The REMP was designed utilizing the guidance" in the Branch Technical Position to the Nuclear Regulatory Commission Regulatory Guide 4.8, Rev. 1, Navember 1979 (12) and ORP/SID 72-2, Environmenta't Radioactivity Surveillance Guide (13).

The REMP was designed:

1. To establish baseline radiological characteristics of the environs of Susquehanna SES for comparison with future data;

2. To assure that media sampled and analyzed are sensitive to fluctuations in the radiological characteristics of the Susquehanna SES environs; and assure that the program will'be responsive to station radioeff1uent dis-char ge;

3. To monitor potential critical pathways of station radioeffluent to man.

Samples for the 1980 REMP were taken from direct, waterborne, airborne and inges-tion pathways with emphasis on those media which would yield data for the evaluation of radiation dose to man. Specific sampling locations were chosen on the basis of potential water use, site meteorology, local demography and land uses.

Environmental sampling locations were divided into two classes, indicator and control. Indicator samples were those collected at locations which were expected to manifest future station effects, if any, and were selected on the basis of distance from the site, topography, hydrology, meteorology, demography, and drainage character-istics. Contro1 samples were collected at locations which are expected to be unaffected by station operation.

Table 1 summarizes the Susquehanna REMP as performed in 1980. Appendix A summarizes the results of the REMP ana1yses and compares indicator and control location results.

Appendix B describes the RMC coding system,'hich specifies sample type and location.

Included in Appendix B, Table B-1 gives the pertinent information on individual sampling locations, while maps B-1 and B-2 show the sampling locations. The data for individual samples are presented 'in tabular form in Appendix C. A synopsis of the analytical pro-cedures used for the samples appears in Appendix D. Appendix E contains the results of RMC's participation in the EPA inter-laboratory comparison program. Appendix F contains the results of demographic data surveys performed in 1980.

Sam le Collection Waterborne pathways were examined by analyzing samples of surface water, ground water, potable (drinking) water and sediment. Surface, ground and potable water samples were collected in unused two gallon plastic containers weekly and monthly. Susquehanna River sediment was also sampled.

Airborne pathways were examined by analyzing air particulates, air iodine and pre-cipitation. Air particulates were collected weekly on Gelman type-A/E, glass fiber fil-ters with low volume air samplers. Air iodine was collected on one inch deep Mine Safety Appliance charcoal cartridges before July 7, 1980. After July 7, 1980 air iodine was collected on one inch deep Science Applications, Inc. charcoal cartridges. The change was made in order to obtain a greater iodine retention efficiency. Air sample volumes were measured with temperature-compensated dry-gas meters. Precipitation samples were collected in unused two gallon plastic containers monthly.'

Ingestion pathways were examined by analyzing samples of fish, milk, pasture grass, game and locally grown food products. Several species of fish samples were collected in spring and late suwer at both the control and indicator locations, filleted and frozen for shipment to RMC. Milk, food products and pasture grass were purchased di-rectly from local farmers. Game samples were obtained by hunting or from road killed animal s.

Direct radiation measurements were made using thermoluminescent dosimeters consisting of calcium sulfate doped with thalium (CaSO (Tm)) (TLDs). The TLDs were placed at loca-tions designed to take advantage of local tr8teorologic, topographic characteristics and pop ul ati on di stribution character is ti cs.

Data Inte retation The radioanalytical and direct radiation data collected during 1980, together with

'that collected previously, will be used as a baseline with which operational data may be compared. 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) a 95/ (a2 sigma) confidence interval is supplied for each result above the lower limit of detection'LLD) with the exception of strontium-89,

-90 analyses, which are reported as minimum detectable level (MDL). Numerically, the LLD is equal to 4.66 times the square root of the quotient resulting from the background counts divided by the background counting time. The result is then divided by a dpm/picocurie conversion factor, the counting efficiency and the sample volume. Whereas the MDL is ficationss equal to 3 times the square root of the quotient resulting from the background counts divided by the background counting time. This result is then divided by the dpm/pico-curie conversion factor, the counter efficiency and the sample volume (the exact speci-of the calculations are noted in Appendix D). The MDL or LLD is, reported when the 2 sigma error exceeds 100/ of the calculated activity. The 2 sigma intervals repre-sent the range of values into which 95/ of repeated analyses of the same sample would fall. The LLD or MDL quoted for particular sample types (Table C-27) are nominal values.

The actual LLD or MDLs are calculated for each sample analyzed and will show variability due to the amount of sample analyzed, the length of time between sample collection and counting, the length of time a particular sample was counted and fluctuations in count-ing background.

It is characteristic of environmental monitoring data that many results occur at or below the LLD. In this report, all results occurring at or below the relevant LLD were reported as being "less than" the LLD value.

Results for each type of sample were grouped according to the analysis, performed.

Averages and standard deviations of these results were calculated when applicable. The calculated standard deviations of grouped data (by location or over time) represent sam-ple rather than analytical variability. For these calculations any values below LLD were considered to be at the LLD. Thus, these averages were biased high and the cor-responding standard deviations were biased low. Averages were not calculated when a group of data was composed of many ()505) LLD values.

As the REMP for Susquehanna SES progressed, in 1980, certain samples and analyses =

were inadvertently omitted from the schedule. These exceptions are delineated, and reasons for the omission stated. However, taking into account all program exceptions, it should be noted that the 1980 Susquehanna SES REMP had a 98/ success rate.

C TLD No sample was received from station 3S4 for the third quarter due to a loss in the field.

~Pro ram ~Chan es In order to provide consistency and clarification of the current status for the environmental monitoring stations, in the vicinity of the Susquehanna Steam Electric Station, an extensive historical investigation was made into each station s nomencla-ture, in 1980. A new aerial map with ring and sector designations was studied to veri-fy the station location code. If it was determined that a station location code was incorrect, it was updated,to agree with the aerial map.

Other changes in nomenclature also include changes in the station number. These changes were made as to chronological priority when the station began operation, the first station in a ring/sector location receives a 1, the second receives a 2 and so on.

13

Specific station code changes are listed below:

I Well water station 5S2 was changed to 4S2.

2. Surface water station 6S2 was changed to 5SB.

3. Air particulate and TLD station 2A1 was changed to 2S2.

4, Air particulate, air iodine and TLD station 11A1 was changed to 11S2.

5. Milk station 10C1 was changed to 10D1.

6. Milk station 9G1 was changed to 10G1.

Additions to the program were made in 1980. These were added in order to better reflect any changes in radioactivity levels during SSES operation. These changes are noted.

1. Surface water station, 6S5, in the discharge area was added for monthly collection.

2. Four surface water stations, 2F2, 3G1, 3G2, 3H3 and one effluent water station, 1DS were added for weekly iodine-131 analysis to try to determine a better back-ground of iodine-131 in the Susquehanna River water.

3. Well water station, 15A4, was added for monthly collection.

\

Four rain water stations, 5S4, 11S2, 1D2 and 12G1 were added for monthly collection.

5. Air particulate station, 50Sg, was added for weekly collection which acts as a qual i ty assurance stati on.

6. Fifty TLD stations were added at various locations in order to comply with or exceed the Branch Technical Position guidelines (12).

7. Three milk stations, 6C1, 5El and 13E3 were added for monthly collection.

Some analyses were added as well. These are noted below.

Strontium-89 and -90 analysis were added to quarterly composites of monthly surface water samples.,

2. Iodine-131 analyses were added to weekly surface water samples from stations 5S8, 1D3 and 12F1.

3. Gross alpha analyses were added to quarterly composites of monthly well water samples.

Iodine-131 analyses were added to weekly potable water samples from station 12H2.

5. Strontium-89, -90 and gross alpha analyses were added to quarterly composites of potable water samples.

6. Strontium-89, -90 and gross alpha analyses were added to semi-annual sediment samples.

7. Strontium-89, -90 and gross alpha analyses were added to quarterly composites of weekly air particulate samples.

14

Strontium-89 and -90 analyses of food and game bone samples was discontinued for 1980 sam-ples because strontium-89 and -90 levels have not changed since 1973. Air iodine charcoal cartridges were changed from thine Safety Appliance to Science Applications, Inc. in July 1980. The new cartridges provide a greater iodine retention efficiency than the previously used cartridges.

REsuos mo nrscussrON RESULTS AND DISCUSSION All environmental samples and TLDs were analyzed by standard RMC analytical proce-dures (14). A synopsis of these procedures appears in Appendix D. Since the precision and accuracy of the analytical results is of paramount importance, ROC devoted a fraction (usually 15-20%) of all analyses to quality control including process quality control, instrument quality control, inter-laboratory cross-check analyses and comprehensive data review. The results of RMC's gC program for 1980 are included in a separate RMC report (15). One important aspect in maintaining laboratory quality control is RMC's partici-pation in the United States Environmental Protection Agency (USEPA) inter-laboratory comparison program. This data appears in RMC's annual gC report and is also presented as Appendix E to this report.

The analytical results of the 1980 REMP have been divided into four categories:

waterborne, airborne, ingestion and direct radiation. The individual samples and anal-yses within each category provide an adequate means of estimating radiation doses to individuals from the principal pathways. The analytical results for the 1980 program are summarized in Appendix A. The data for individual samples are presented in tabular form in Appendix C. The sensitivities stated in the Branch Technical Position were met for all samples (12).

Waterborne Pathw The waterborne pathways of exposure from Susquehanna SES were evaluated by analyzing samples of surface water, well water, potable water and sediment.

Surface Water (Tables C-l, C-2, C-3 and C-4)

The Susquehanna River was sampled at eleven locations. Daily grab samples were col-lected at 12H1 (Merck Company) then composited into a monthly sample. Monthly samples were also composited from weekly grabs at station 5S8 (under the power line) and beginning on 9-10-80 at station 6S5 (outfall area). Monthly grab samples were collected at station 1D3 (Mocanagua Substation), station 13E1 (Glen Brook Reservoir), station 12F1 (Berwick Bridge) and station 12G2 (between Bloomsburg and Bewick). Monthly surface water samples were analyzed for gross beta, gamma emitters and iodine-131. quarterly composites were analyzed for tritium, strontium-89 and -90.

Weekly grab samples were collected from stations 1D3, 12F1, 2F2 (Retreat Bridge), 3Gl (Lower Bridge Plymouth), 3G2 (Nanticoke Bridge) and 3H3 (Market Street Bridge) and weekly composite samples were collected from stations 5S8 and 12Hl in order to study the occurrence of detectable concentrations of iodine-131 in the river water. Weekly iodine-131 analyses were started in May 1980 for station 12F1, September 1980 for station 1D3 and October 1980 for stations 5S8, 2F2, 3G1, 3G2 and 3H3. Beginning in July 1981 a monthly effluent water grab sample was collected at station 1D5 (Shickshinny Sewage Treatment facility) for iodine-131 analysis.

Analysis for beta emitters in samples of surface water showed detectable activity in 50 of 76 samples, with results ranging from 1.5 to 6.7 pCi/1. The gross beta results were consistent with the data previously obtained from 1972-1979 (4-11). Garana analysis of the surface water samples showed all gamma emitters to be below the LLD.

Positive iodine results, in surface water, were reported in 28 of 177 samples with values ranging from O.ll to 0.9 pCi/l. After positive results were observed in the mon-thly samples, weekly iodine-131 was initiated at several stations throughout the year.

Also, additional sampling locations were added for monthly and weekly iodine-131 analyses.

All months except March, April and July showed positive iodine-131 concentrations, in some samples. Since Susquehanna SES is not in operation, iodine-131 in the surface water can be attributed to other sources of contamination of the river.

19

The analysis of tritium in surface water showed detectable activity in ll of 25 sam-ples with results ranging from 63 to 168 pCi/1. This's well below the action level of 20,000 pCi/1 as quoted in the Branch Technical Position (12). The average tritium concen-trations in surface water samples shows a gradual decline for the period 1973 to 1980.

This is likely the result of a reduction in atmospheric tritium from nuclear detonations.

Average triti.um concentrations for all locations since 1973 were graphed in Figure 1.

Positive tritium results are reported when the 2 sigma counting error is less than the re-sult. In some cases, this may cause positive results to be reported, which are lower than the calculated LLDs. For clarification of the method of calculation, see Appendix D, Analysis of Water Samples for Tritium.

Levels of strontium-89 were below HDL (0.6 to 2.4 pCi/1) in twenty-four of twenty-five samples. Strontium-89 was found in one sample. The concentration (0.9 0.7 pCi/l) was comparable to the NOL levels found in the samples. Levels of detectable strontium-90 ranged from 0.3 to 0.8 pCi/1 in ten of the twenty-five samples. The ILL values ranged from 0.4 to 1.0 pCi/l.

Well Water (Tables C-5, C-6 and C-7)

Three wells, the peach stand on-site (4S2), the Serafin Farm (15A4) beginning on 3-26-80 and the Berwick Water Co. (12F3), were sampled monthly. Gross beta and gamna analyses were performed on the monthly samples. Gross alpha and tritium analyses were performed on quarterly composites of monthly grab samples.

Gross beta results showed positive values in 16 of 34 samples with results ranging from 1.4 to 5.1 pCi/1. LLDs ranged from 2.2 to 2.9 pCi/l. All results for all gambia emitting nuclides were less than LLD. Positive alpha results were observed in three of twelve samples with an average of 2.1 pCi/1. The LLD values ranged from 0.9 to 2.7 pCi/1. Five of twelve samples showed positive tritium results, ranging from 89 to 150 pCi/1 and LLDs ranging from 107 to 123 pCi/1. Positive results for gross beta, gross alpha and tritium compared closely to the respective LLDs for those analyses and to results found in previous REMP reports (4-11).

Potable (Drinking) Water (Tables C-8, C-9 and C-10)

Potable water was sampled monthly at two locations, the Berwick Water Company (12F3) and the Danville Water Company (12H2). In addition, weekly samples were collected from station 12H2 beginning on April 21, 1980 for iodine-131 analysis. Gross beta and garma emitters were analyzed monthly. Gross alpha, tritium and strontium-89 and -90 were anal-yzed as quarterly composites.

Thirteen of twenty-three samples showed positive gross beta results ranging from 1.7 to 3. 1 pCi/1 and averaging 2.4 pCi/l. All results from all gamma emitting nuclides were less than LLD.

One sample collected from September and one sample collected from November showed positive results (both 0. 12 pCi/1) for iodine-131 analyses at the Danville Water Company.

This was found to be consistent with iodine-131 activity in weekly surface water samples.

Gross alpha was observed in one of eight samples. The result, 1.3 pCi/l, fell within the LLD range of 0.8 to 2.6 pCi/1. These results compare favorably to the EPA drinking water action level of 15 pCi/1 for gross alpha (16).

Five of eight samples analyzed showed positive tritium res'ults ranging from 96 to 116 pCi/1, with LLDs ranging from 107 to 137 pCi/1 for the others. The results fall below the EPA tritium action level of 20,000 pCi/1 for drinking water (16).

20

The tritium results, for potable water, were consistent with results for tritium observed in surface water of the Susquehanna River.

All results for strontium-89 were below the MDL of 0.6 to 1.9 pCi/1. Two detectable concentrations of strontium-90 (0.7 and 1.0 pCi/l) were observed in eight samples. The MDL values ranged from 0.4 to 0.8 pCi/1.

Sediment (Tables C-ll and C-12)

Sediment samples were taken from three locations in the Susquehanna River semiannually.

Samples were taken at Bell Bend (7B), downstream near Hess Island (11C) and upstream near Gould Island (2B). Samples were analyzed for gamma emitting nuclide, gross alpha, stron-tium-89 and -90.

Naturally-occurring K-40, Ra-226 and Th-232 were detected in all samples. Be-7, from cosmic ray activity, was also observed in five of the six samples analyzed. Cs-137 was de-tected in all samples, with levels ranging from 0.04 to 0. 10 pCi/g(dry). These nuclides been observed periodically throughout the program. Since the station is not in oper- 'ave ation, and there are no other nuclear power installations in the area, the man-made nuclides observed were attributed to nuclear weapons testing fallout.

Gross alpha analyses showed positive values for all samples, ranging from 5. 1 to 15 pCi/g(dry). All strontium-89 results were below 0. 1 pCi/g(dry). One sample showed a posi-tive strontium-90 concentration of 0.04 pCi/g(dry). All others were below the MDL (0.05 to 0.09 pCi/g(dry)).

~Aib P The airborne pathways of exposure from Susquehanna SES were evaluated by analyzing sam-ples of air particulates, air iodine cartridges and precipitation. Samples of air particu-lates were collected at ten stations; the Information Center (2S2), the biological laboratory (5S4 and 50Sg), the Goloumb House (11S2), transmission line east of route ll (9B1), the Mocanagua Substation (1D2), near Pond Hill (3D1), the Berwick Hospital (12El), at Bloomsburg (12Gl) and the PPRL roof in Allentown (7Hl). Stations 2S2 and 50Sg began operations in August. Air filters were analyzed weekly for gross beta and quarterly for gamma emitters, gross alpha and strontium-89 and 90. Air iodine was collected on charcoal cartridges in series with the air particulate filter at stations 2S2, 5S4, 11S2, 981, 12E, 50Sg and 7H1.

The charcoal cartridges have an efficiency of removal of elemental iodine of 99K. Sampling for air iodine began at stations 2S2 and 50Sg in August. Precipitation samples were collected monthly beginning in April from stations 5S4, 11S2, 1D2 and 12G1 and analyzed for tritium and gamma emitters.

Ai r Particulates (Tables C-13, C-14 and C-15)

The gross beta concentrations of each sample was determined weekly. These concentra-tions ranged from 0.007 - 0.036 pCi/cubic meter in all samples collected between January and October. An increasing tree) is noted in Iiovember and December eith concentrations ranging between 0.027 to 0.086 pCi/m . This can be attributed to the fallout from the atmospheric nuclear weapons test by the Peop)e's Republic of China on October 15. The annual average for all stations was 0.024 pCi/m . Figure 2 shows graphically the gross beta activity in air particulates for 1980.

quarterly composites of air particulate filters from each location were analyzed by gamma spectrometry. Be-7, from cosmic radiation, was detected in all 34 samples. Beryl-lium-7 results for the Susquehanna SES site vicinity show an increase in the second quar-ter. This trend is typical of the spring maximum concentration of fallout in the tropos-21

phere due to the winter maximum exchange of fallout between lower stratosphere and the troposphere at temperate and high latitudes (17), with high latitudes being defined as those latitudes between 50'nd 90'.. Cs-137 was observed in four of 28 samples. Nb-95, Zr-95, Ru-103 and Ce-141 were observed in all fourth quarter samples. These may be attri-buted to the atmospheric nuclear weapons test by the People's Republic of China on October 15.

Gross alpha analyses of quarterly composites showed positive results in thirty-three of thirty-four samples with values ranging from 0.0002 to 0.0049 pCi/cubic meter with the average being 0.0032 pCi/cubic meter.

The strontium-89 analyses performed on the quarterly composites showed two out of thirty-four samples with detectable activity. These were 0.0038 and 0.0028 and fall within the MDL.range. The MDLs for strontium-89 ranged between 0.0003 and 0.0077 pCi/

cubic meter. Strontium-90 concentrations ranged between <0.0003 and 0.0038 pCi/cubic m ter with the average being 0.0005 pCi/cubic m ter.

Air Iodine (Table C-16)

Of the 295 air samples analyzed for iodine-131, one showed a detectable level of 0.02 pCi/cubic meter. The sample was analyzed on June 19, 1980 at which time a recount was performed. Three half-lives had passed and, as was expected, the result was less than the LLD. Any iodine-131 which may have been present had decayed away to a level

. lower than could be detected. The air particulate filter for that week showed no ele-vation in gross beta activity. Station 981 was monitored following that week but no I-131 was found. No further investigation as to the source of the I-131 concentration in the sample was possible due to the number of half-lives that had passed since the sample stop date. The detection limit for all others ranged from 0.003 to 0.07 pCi/cubic meter.

Precipitation (Table C-17)

Three of thirty-two samples showed positive tritium results, ranging from 99 to 126 pCi/l. All others were less than LLD (231 pCi/1). Be-7 was observed in.24 samples ranging from 19 to 110 pCi/1. The presence of Be-7 throughout the year can be attributed to cosmic ray activity. All other results from gambia emitting nuclides were below the LLD.

In estion Pathwa 4

Ingestion pathways of exposure from Susquehanna SES were evaluated by analyzing samples of milk, fish, food products, meat, gave and pasture grass.

Milk (Tables C-18 and C-19)

Milk samples were collected at eight dairy cattle locations. Samples were collected monthly except in October when an extra sample was collected from stations 1282, 12B3, 10D1 and 10G1 following the atmospheric muclear weapons test by the People's Republic of China on October 15. Each sample was analyzed for I-131, Sr-89, and -90 and garana emitters.

The extra October samples were analyzed for I-131 only.

Of the eighty-eight samples analyzed for I-131, five showed detectable levels ranging from 0.27 to 1.6 pCi/1. These levels were found in November and Decenher samples and may be attributed to fallout from the atmospheric nuclear weapons test by the People's Republic of China. The LLDs ranged from 0.07 to 0.3 pCi/1.

22

Strontium-89 was detected in ten of seventy-six samples analyzed with results ranging between 1.7 and 6.7 pCi/l. The range of MDL values for strontium-89 was 1.7 to 29 pCi/l.

The wide range of values for the MDL was due to low chemical yields in some of the samples and delays between sample collection and analysis which causes a large decay correction factor. The concentration of strontium-90 was positive in seventy-three of seventy-six samples analyzed and averaged 4.3 pCi/1. The MDL range was 2.2 to 7.1 pCi/1. Due to the 28 year half-life and biological assimilation, strontium-90 can be expected to remain long after routine atmospheric testing has ceased. All strontium-89 and -90 analysis chemical yields have been verified by atomic absorption to determine calcium interference.

Potassium-40 as determined by gamma spectrometry, was found in milk samples, with levels ranging from 1100 to 2000 pCi/1. Cs-137 was found in twenty-five of seventy-eight samples in levels ranging from 1.4 to 4.2 pCi/1.

Goat milk was sampled quarterly at one location, or more frequently if sufficient milk was available. Goat milk was analyzed for iodine-131 only. Of the seven samples analyzed, one sample had a positive result of 1.7 pCi/1 which is likely the result of fallout from the atmospheric nuclear weapons test on October 15.

Fish (Table C-20)

Fish was collected from two locations. Three to seven fish of each species were col-lected at each location. The species included were: walleye, white sucker and channel catfish, Analysis of the flesh for gamma emitters and strontium-89, -90 was performed on each species sampled.

Strontium-89 was below the MDL (0.006-0.02 pCi/g(wet)) in eleven of twelve samples.

A positive strontium-89 result was observed in the white sucker sample taken at the con-trol location. The value of 0.011 pCi/g(wet) is comparable to the range of HDL values and agrees with the occasional positive strontium-89 results observed in previous years (4-11). No strontium-90 was observed in any samples with MDLs ranging from 0.003 to 0.01 pCi/g(wet)..

Gamma spectrometry was performed on the flesh portions of fish samples. Naturally-occurring K-40 was detected in all twelve samples with results ranging from 2.8 to 4.0 pCi/g(wet). Cesium-137 was detected in two walleye samples, at 0.012 and 0.042 pCi/g(wet)

These results were consistent with those previously found. Since the station is not in operation, and there are no other nuclear power installations in the area, the man-made nuclide observed can probably be attributed to nuclear weapons testing fallout.

Food Products (Table C-21)

Gamma spectrometry was used to analyze various types of food products collected from various local farmers within the vicinity of Susquehanna SES. These include tomatoes, honey, potatoes, squash, potato chips, strawberries, corn, cabbage and apples. Naturally-occurring K-40 at levels of 0.7 to 7.2 pCi/g(wet) was found in all samples. All other gamma emitting nuclides were below the respective LLDs.

Meat (Table C-22)

Meat samples consisting of eggs, chicken, beef, pork and duck were collected from three local farms. The flesh and bones or shells were analyzed for gamma emitters.

Natu'rally-occurring K-40 was detected in nine of ten samples, 1.5 to 2.8 pCi/gram(wet) in flesh, and 5.6 to 9.5 pCi/gram(wet) in bones and shells. Cs-137 was also found in the beef sample (0.02 pCi/g(wet)). All others were less than the LLD of 0.03 pCi/g(wet) for flesh and 0.06 pCi/g(wet) for bones and shells.

23

Game (Table C-23)

One deer sample was collected in the winter and the flesh and bones were analyzed for gamma emitters. Naturally-occurring potassium-40 was found in the flesh and bones at levels of 2.9 and 1.8 pCi/g(wet), respectively. Cesium-137 was also found at a concentration of 0.03 pCi/g(wet) for flesh and 0.016 pCi/g(wet) for 'bones. These results were consistent with cesium-137 concentrations found in meat samples. Radium-226 was found in the deer bones with a concentration of 0.07 pCi/g(wet). All other nuclides searched for were less than the LLD.

Vegetation (Table C-24)

Two leafy vegetation samples and one acorn sample were collected on site and analyzed by gamma spectrometry. Potassium-40 was found in all three samples at concentrations of 0.94 to 2.3 pCi/g(wet). Also, Cs-137 was found in the acorn sample taken on August 4 at a concentration of 0.22 pCi/g(wet). This is consistent with a previous study to determine the source of elevated levels of cesium-137 in squirrels. The study concluded that the ele-vated cesium-137 levels in the squirrels was due to the elevated levels of cesium-137 in the acorns which were ingested by the squirrels (7).

Pasture Grass (Table C-25)

Pasture grass was collected monthly at the'closest farm. In addition, an extra sample was collected in October in order to monitor any fallout due to the atmospheric weapons test by the People's Republic of China. One pasture grass sample was collected from station 8D1 when the goat milk was unavailable. Each sample was analyzed by gamma spectrometry. Beryl-lium-7 and potassium-40 were found in seven of thirteen samples and twelve of thirteen sam-ples, respectively. Beryllium-7 concentrations ranged from 0.6 to sium-40 concentrations ranged from 0.6 to 7.5 pCi/g(wet).

ll pCi/g(wet) and potas-The pasture sample from station 15Al collected on December 5 showed detectable levels of Zr-95 (0.26 pCi/g(wet)), Hb-95 (0.31 pCi/g(wet)), Ru-103 (0.25 pCi/g(wet)), Ba-140 (0.7 pCi/g(wet)), La-140 (0.39 pCi/g(wet)), Ce-141 (0.59 pCi/g(wet)), and Ce-144 (0.2 pCi/g(wet)).

These levels can be attributed to fallout from the atmospheric nuclear weapons test by the People's Republic of China on October 15 and agree with the elevated gross beta in air par-ticulates and the positive gamma spectrometry results in the fourth quarter composites of air particulates. These nuclides are typically found in fallout from atmospheric nuclear weapons tests (4-11).

Direct Radiation (Table C-26)

Direct radiation measurements were made on a quarterly basis. TLD packets were placed at 66 locations on and surrounding the Susquehanna SES.- During 1980, 186 quarterly TLD pa-ckets were collected. Each packet included four dosimeters for a total of 744 analyses.

All TLD results presented in this report have been normalized to a standard month (30.4 days) to eliminate the apparent differences in data caused by variations in length of exposure period. The range of TLD results for indicator locations was 4.53 to 16.78 mrem/standard month and 3.99 to 7.04 mrem/standard month for control locations. Elevated levels at loca-tions 6S4 and 7S3 in the third and fourth quarters were due to on-site radiographic activity.

The TLD analyses yielded an average dose equivalent rate of 6.17 mrem/standard month at all indicator locations, and an average dose equivalent rate of 5.64 mrem/standard month at all control locations.

The projected annual dose from direct radiation computed from these results is 74 mrads, or 74 mrem assuming a quality factor of I, at indicator locations, and 68 mrad or 68 mrem at 24

the control locations. The EPA terrestrial and cosmic radiation dose rate calculated for the Wilkes-Barre area is 82 mrem/year, neglecting any neutron contribution (18). This com-pares favorably with the average TLD measured dose rate of 73 mrem/year for all stations.

This difference is not unexpected since the EPA values are gross general averages for an area" and do not take into consideration specific terrestrial variations. The average dose rates for all monitoring locations since 1973 are plotted in Figure 3. The differences observed between locations or between sampling periods were similar to those found pre-viously (4-11).

CONCLUSIONS CONCLUSIONS The Radiological Environmental Monitoring Program for Susquehanna SES was conducted during 1980 as a continuation of the program initiated in 1972. The data collected during 1980 further develops a baseline for comparison with future operational data.

The purposes for the design and development of the Susquehanna SES REMP were:

1. To establish baseline radiological characteristics of the environs of Susquehanna SES for comparison with future data;

2. To assure that the media sampled and analyled are sensitive to fluc-tuations in the radiological characteristics of the Susquehanna SES environs; and assure that the program will be responsive to station radioeffl uent discharge;

3. To monitor potential critical pathways of station radioeffluent to man.

The 1980 REMP further establishes the, baseline radiological characteristics for the vicinity of the Susquehanna SES. This is evident by the continuation of sampling and analysis for the aquatic, atmospheric and terrestrial environments, as well as mon-itoring of direct radiation. The sampling and analysis of these media reflect the nor-mal background radiation found in this environment.

fm The media sampled by the Susquehanna REMP are sensitive to radiological fluctuations of the environment monitored. This is evident by the measured gradual decline in the sur-face water concentration of tritium, primarily due to the decrease in atmospheric nuclear

,g detonations. Gross beta and garana spectrometry analyses of air particulates are sensitive to atmospheric testing of nuclear weapons. Gamma analyses of air and pasture grass sam-ples showed low concentrations of radioactive nuclides from fallout from the October 15, lg 1980 atmospheric nuclear weapons test by the People's Republic of China. Iodine-131 was

~5 detected in extremely low concentrations in milk samples in November and December. Iodine-131 analysis of air cartridges indicated that the levels were below the detection limits which -suggests that analysis of milk for iodine-131 is an excellent indicator for tracing the iodine-131 pathway. Supporting this pathway theory are the results of garana spectro-metry of the December pasture grass sample from the Seraiin farm. The nuclides found are typical of fallout and are not different from those found in the air particulate samples.

'g , The probable explanation for not finding evidence of fallout in the other samples collected in November and December is that the fallout nuclides had not yet been concentrated to the limits of detection. Samples collected later indicated that, this was the case. This in-sures that the Susquehanna SES REMP is sensitive to radiological fluctuations of the envi-ronment.

Environmental gamma radiation measurements were made using thermoluminescent dosimeters.

Results, from the indicator and control'locations were found not to be significantly different as would be expected in the absence of any source of garma radiation.

The media sampled by the Susquehanna REMP also monitors potent'ial critical pathways of station radioeffluent to man.

Monitoring of the waterborne pathway consisted of sampling surface water, well water, potable water and sediment and were chosen to reflect the characteristics of normal back-ground radiation for this medium. The airborne pathway was monitored by filtering and analyzing the particulate matter, by passing filtered air through a charcoal filter which was analyzed for the presence of iodine-131 and by analysis of precipitation. The ingestion pathway was monitored by the sampling and analysis of milk, fish, game, and various food pro-29

ducts. The results obtained by analysis of these samples were consistent with previously m asured levels of radioactivity, in their respective media (4-11).

The results obtained from analyses performed on the samples indicates that the levels and fluctuations of radioactivity detected in the vicinity of the Susquehanna SES were expected for this environm nt and are consastent with previously accumulated REHP data (4-ii).

Ho detectable measuresnnts were found.

The LLDs quoted are the lowest actual LLD obtained in the various acedia during the reporting period. A typical gamna LLD was determined for each searched for nuclide as found in Table C-27. Where all nuclides were <LLD for a specific media no LLD was listed. Strontium-89 and -90 are reported as minimum detectable levels (MDLs) rather than LLDs.

(2) Mean and range based upon detectable neasurem'nts only. Fraction of detectable measurements is indicated in parentheses.

n The mean (X) is defined as follows: )I = E X,. Where: Xi

= the activity of an individual measurement (i) i=1 n = number of total measurements

APPENDIX B SAMPLE DESIGNATION

APPENDIX B Table B-I lists the sampling locations and includes both the distance and direction from the Susquehanna SES and the media sampled at each location. Maps B-I and B-2 show the sampling locations with respect to the Susquehanna SES.

Sample Designation Samples are identified by a three part code. The first two letters are the power station identification code, in this case "SS" for Susquehanna Steam Electric Station.

The next three letters are for the acedia sampled.

AIO = Air Iodine FPV = Food Products, Vegetables AQF = Fi sh GAD = Game, Deer AQS = Sedim nt GMK = Goat Milk APT = Air Particulates IDM = Inmersion Dose (TLD)

EWA = Effluent Water MET = Meat FPB = Food Products, Beef MLK = Milk FPE = Food Products, Eggs PAS = Pasture Grass FPF = Food Products, Fruit PWT = Potable Water, Treated FPG = Food Products, Grain RWA = Precipitation FPH = Food Products, Honey SWA = Surface Water FPL = Food Products, Leafy Vegetables WWA = Well Water FPP = Food Products, Poultry VGT = Vegetation ,

The last four symbols are a location code based on direction and distance from the site. Of'these, the first two represent each of the 16 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 direction; i.e., 2=NNE, 3NE, 4=ENE, etc. The next digit is a letter which represents the radial distance from the station:

S = Si te (I)

' ocati on E = 4-5 miles off-site A = O-l miles off-site F =- 5-10 miles off-site 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 miles off-site The last nuoher is the station nuoerical designation within each sector and zone; e.g. l. 2, 3, . . . .

Specific information about the individual sampling locations is given in table B-l.

Maps B-1 and B-2 show the locations of sampling stations with respect to the site.

1. Site is defined as that area within PPSL's property boundary.

APPENDIX D SYNOPSIS OF ANALYTICAL PROCEDURES

GROSS ALPHA ANALYSIS OF SAMPLES Total Water (AH)

A 250 ml aliquot is evaporated to dryness and transferred to a preweighed, 2" x 1/4" ringed planchet and reweighed. The planchet is then counted in a low background gas-flow proportional counter. Sel f-absorption corrections are made based on the measured residue weight and calculated thickness. The calibration standard used is Pu-239.

A 250 ml sample of distilled water is evaporated in the same manner and used as a blank.

Sediment (A9)

A 200 mg portion of finely divided sediment is slurried with water, transferred to l a planchet and dried. The sample is counted in a low background, gas-flow propor-tional counter. Self absorption corrections are made on the basis of the weight of material counted. An empty planchet is prepared with water and used as a blank.

Air Pa'rticulates (AE)

A 204 aliquot of the leached sample is evaporated to dryness on a preweighed, 2" x 1/4", ringed, stainless steel planchet and the planchet is reweighed. The planchet is counted in a low background, gas-flow proportional counter. Self absorption cor-rections are made on the basis of residual weight. An unused filter paper is pre-pared in the same manner and counted as the blank.

Calculations of the results, the two sigma error and the lower limit of detection (LLD).

Result (pCi/vol or mass) = ((S/T) - (8/t)) / (2.22 V E TF) 2 sigma error (pCi/vol or mass) = 2 ((S/T ) + (8/t )) / (2.22 V E TF)

LLD (pCi/vol or mass) = 4.66 (8 ) / (2;22 V E TF t)

Where: S = Gross counts of sample including blank 8 = Counts of blank E = Fractional Pu-239 counting efficiency T = Number of minutes sample was counted t = Number of minutes blank was counted V = Volume of aliquot (liters, cubic meters or grams)

TF = Transmission factor (based on- net weight of sample in counting planchet)

Air Particulates (BD)

After a delay of two to five 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 filter paper is counted as the blank.

Calculations of the results, the two sigma error and the lower limit of detection (LLD).

Result (pCi/m ) = ((S/T) - (B/t)) / (2.22 V E) 2 sigma error (pCi/m ) = 2 ((S/T ) + (B/t )) / (2.22 V E)

LLD (pCi/m ) = 4.66 (B ) / (2.22 V E')

Where: S = Gross counts of sample including blank B = Counts of blank E = Fractional Sr-90-Y-90 counting efficiency T = Number of minutes sample was counted t = Number of minutes blank was counted V = Sample aliquot size (cubic meters) 102

ANALYSIS OF SAMPLES FOR TRITIUM Water (H2)

A 15 ml aliquot of the sample is vacuum distilled to eliminate dissolved gasses and non-volatile matter. The distillate is frozen in a trap cooled with a dry ice-isop'ropanol mixture. Eight (8) ml of the distillate are mixed with ten (10) ml of Insta-Gel liquid scintillation solution. The sample is then counted for tritium in a liquid scintillation counter. A sample of low tritium (< 50 pCi/1) water is vacuum distilled as a blank and is counted with each batch of samples.

'In the calculation of the result it is assumed that the condensated and original sample are of equivalent volumes. The volume change associated with the removal of dissolved gases and non-volatile matter is not significant compared to the other errors in the analysis.

Calculations of the results, the two sigma error and the lower limit of detection (LLO).

RESULT (pCi/1) = ((S/T) - (B/t)) / (2.22 V E) 2 SIGMA ERROR (pCi/1) = 2 ((S/T ) + (B/t )) / (2.22 V E)

ANALYSIS OF SAMPLES FOR IODINE-131 Milk or Water (Ig)

The initial stable iodide concentration in milk is determined with an iodide ion specific electrode. Thirty milligrams of stable iodide carrier is then added to four (4) liters of milk. The iodide is removed from the milk by passage through ion-exchange resin. The iodide is eluted from the resin with sodium hypochlorite, and purified by a series of solvent extractions with the final extraction into a toluene phase. The toluene phase is mixed with a toluene-based liquid scintillation solution. The sample is then counted in a beta-gated gamma coincidence detector, shielded by six inches of steel. Distilled water is used as a blank. The yield is calculated from stable iodide recovery based on the recovered volume. Results are corrected for decay from the sampling time to the middle of the counting period, using a half-life value for I-131 of 8.06 days.

Air Cartridges (Il)

An iodine absorber composed of charcoal is emptied into an aluminum can (6 cms high by 8 cms in diameter) and counted with a HaI (Tl) detector, coupled to a mul ti-channel pulse height analyzer.

Calculation of results, two sigma error and the lower limit of detection (LLD).

The data are obtained by smoothing the spectrum to eliminate spurious statistical noise. Iodine-131 is identified by fitting the spectrum to a Gaussian curve, and noting the net area, in counts, above the baseline projection. The calculations of the results, the two sigma error and xhe lower limit of detection (LLD) for Iodine-131 are then expressed in activity (pCi) per unit volume (liter or cubic meter, depending whether the sample is either milk and water or air).

ENVIRONMENTAL DOSIMETRY (Dl)

By RMC definition, a thermoluminescent dosimeter (TLD) is considered one end of a capillary tube containing calcium sulfate (Tm) powder as the thermolumi-nescent material. This material was chosen for its characteristic high .light output, minimal thermally induced signal loss (fading), and negligible self-dosing. The energy response curve has been flattened by a complex multiple element energy compensator shield supplied by Panasonic Corporation, manufac-turer of the TLD reader. There exists four dosimeters per station sealed in a polyethylene bag to demonstrate integrity at the time of measurement, and for visualization of the sample placement instructions. The zero dose is determined from TLDs located in the lead shield found at RMC, Philadelphia.

Following the predesignated exposure period the TLDs are placed in the TLD reader. The reader heats the calcium sulfate (Tm) and the measured light emission (luminescence) is used to calculate the environmental radiation expos ure.

Data are normalized to standard machine conditions by correcting machine settings to designated values before readout. Data are also corrected for

, in-transit dose using a set of TLDs kept in a lead shield in the field, exposed only during transit. The average dose per exposure period, and its associated error is then calculated.

The Cs-137 source is used to expose TLDs as a reference sample. An. absorbed dose in tissue is determined using the 0.955 rad/Roentgen conversion factor and dose equivalent (mrem) by using a quality factor of 1.

Calculation of results and two sigma error:

Gross TLD (i) = (TLD(i)-D0(i)) x CF (i) x CF (ins) x 0.955 mrad/mRoentgen ITD = NET (site 9) - (NET(RMC tI) (D(sta) / D (RMC g)))

NET TLD(i) = gross TLD(i) - ITD n

AVG = ((si gma NET TLD) / n) (D(STD) / D (EX) )

1=1 ERROR (95K CL) = t(n-1) (sigma NET TLD (i) / n) (D(STD) / D (EX))

APPENDIX E RESULTS OF THE EPA INTER-LABORATORY COMPARISON PROGRAM

I INTER-LABORATORY COMPARISON PROGRAM RMC participates in the EPA radiological interlaboratory comparison'cross check) program.

This participation includes a number of analyses on various sample media as found in the Susquehanna SES REMP. As a result of participation in the program an objective measure of analytical precision and accuracy as well as a bias estimation of RMC results is ob-tained. Of the 140 analyses performed, 118 fell within the EPA mean and standard deviation.

Reference 15 discusses discrepancies between the data when they occurred. Tables E-l, E-2, E-3 and E-4 summarize the results of 1900 samples as well as 1979 samples for which the EPA mean and the All Participants mean was unavailable as of the printing of the 1979 Annual Report (11).

• Results are not available at this time.

(1) The analyses were performed at a later date than the EPA intended, thus allowing decay of expected activity.

(2) The result of the EPA intercomparison program for Gross Beta in July, RMC A'34561 Air Particulate, is not acceptable. Thorough investigations were performed such as counter efficiency and background counts, but there were no findings. Sample preparation at EPA was suspected because 32% of the participating laboratories were outliers. This information was obtained, from EPA by telecon on October 7, 1980. New equipment was introduced to prepare the cross check samples for filters in June, 1980. This could be the reason that a high outlier rate was shown on this sample.

(3) Beta contamination is suspected since the alpha results agree. Sample may have been spiked twice at the EPA.

APPENDIX F SITE SPECIFIC DEMOGRAPHIC DATA

SITE SPECIFIC DEHOGRAPHIC DATA The Branch Technical Position (12) requires the annual collection of certain demographic data in order to determine if any changes to the REHP are necessary.

over 50 square meters and residence The nearest milk producer, vegetable garden in each sector must be determined.

Dair Animal Surve In October 1980, a dai'ry animal survey was performed, in the vicinity of the Susquehanna Steam Electric Station. The information, pertaining to the location of the nearest dairy animal (within 5 miles) is listed in Table F-1. Since there are no changes in the location of the nearest dairy animal, no change in the REHP is necessary.

Ye etable Garden Surve In lieu of a vegetable garden survey, vegetation was collected from a garden in the sector with highest D/9 and analyzed for iodine-131.

Residence The location of the nearest residence in each sector is listed in Table F-2; 127
