SUMMARY

AND CONCLUSIGHS

I. Summary and Conclusions This report on the preoperational Radiological Environmental Manitoring program conducted at the Limerick Generating Station for philadelphia Electric Company covers the period January 1, 1982 through December 21, 1984. During that time period, 6321 analyses ware performed on 4858 samples.

Surface and drinking (potable) water samples were analyned for concentrations of gross beta (soluble and insoluble fractions),

tritium, and gamma emitting nuclides. Concentrations detected in both indicator and control locations were consistent with e..ch other.

High sensitivity I-131 analyses were performed on weekly air ocmples. All results were less than the minimium detectable level.

Air particulate samples were analyzed for concentrations of gross bota and gamma emitting nuclides. Results of samples collected from indicator and control locations showed slight but statistically significant differences.

Environmental ambient gamma radiation measurements were made centhly using thermoluminescent dosimeters. Site boundary locations chowed lower ambient gamma radiation levels than distant locations.

A variety of radionuclides, both naturally occurring and man-made, ware detected in the environs of Limerick Generating Station at levels expected for that environment. The detection of these indicated that the Limerick REMP was sensitive to radiological fluctuation in the onvironment around the Limerick Generating Station.

INTRODUCTION

LIMERICK GENERATING STATION Preoperational Radiological Environmental Monitoring Program II. Introduction The Limerick Generating Station (LGS), consisting of two 1055 MWe boiling water reactors owned and operated by Philadelphia Electric Company (PEco), is located adjacent to the Schuylkill River in Montgomery County, Pennsylvania. The site is located in Piedmont countryside, transversed by numerous valleys containing san 11 tributaries which feed into the Schuylkill River. On the eastern river bank elevation rises from approximately 110 to 300 feet mean sea lovel (MSL). On the western river bank elevation rises approximately 50 feet MSL to the western site boundary.

A Radiological Environmental Monitoring Program (REMP) for LGS was initiated in 1971. Review of the 1971 through 1977 REMP data resulted in the modification of the program to comply with changes in the Environmental Report Operating License Stage (EROL)(13 and the current revision of the Branch Technical Position paper.823 The time period from January 1, 1982 through December 31, 1984 has been divided into the preoperational and the operational period. The preoperational poriod, discussed in this report, covers the time prior to Unit 1 ochieving initial criticality. The Regional Radiological

.. Environmental Monitoring Program ReportI33, published previously, discussed the period the 1984 after Unit 1 reached initial criticality. For comparison purposes the preoperational period's locations have been designated as " control" and " indicator" to correspond to the operational program. Statistical analyses of the preoperational data from control and indicator locations were preformed to identify any statistical differences prior to the plant's initial operation.

3-

A. Objectives The objectives of the preoperational Radiological Environmental Monitoring program are:

1. To provide data on measurable levels of radiation and radioactive materials in the site environs.

2. To establish the baseline radiological data necessary to support the o p e r a t i o n a l p r o g r a m's evaluation of the relationship between quantities of radioactive material released from the plant and resultant radiation doses to individuals from principal pathways of exposure.

B. Implementation Implementation of the stated objectives was accomplished by identifying significant exposure pathways, and continuously monitoring those media prior to plant operation.

In order to achieve the stated objectives, the preoperational program included the following analyses on sam;1es collected:

1. Concentrations of tritium in surface water, drinking (potable) water, and well water.

2. Concentrations of beta emitters in surface unter, drinking (potable) water, and air particulates.

3. Concentrations of gamma emitters in surface, drinking (potable), well water, air particulates, milk, vegetation, game, fish, and sediment.

4. Concentrations of I-131 in air and milk.

5. Ambient gamma radiation levels at various site environs.

PROGRAM DESCRIPTION

III. program Description A. Sample Collection This section describes the collection methods used to obtain environmental samples for the LGS REMp during the preoperational period.

Acuatic Environment The aquatic environment was examined by analyning samples of surface water, drinking water, fish, and sediment. Two gallon water samples were collected monthly from five surface water locations (10F2, 15F5, 16B2, 2451, and 24S2) and five drinking water locations (13H2, 15F4, 15F7, 16C2, and 28F3). The collection methods used throughout the preoperational period are described in the program History.Section III.C. Control locations were 10F2, 2451, and 2452 for surface water and 28F3 for drinking water. All containers used were new unused plastic bottles, which were rinsed at least twice with source water prior to collection. Fish samples comprising the flesh of two groups, catfish / bullhead (bottom feeder) and sunfish (predator), were collected semi-annually at three locations: 16C5 and 20S1 (indicators) and 29c1

- (control). Sediment samples composed of recently deposited substrate were collected at three locations semi-annually: 16B2 and 16C4, (indicators) and 33A2 (control).

Atmospheric Environment The atmospheric environment was examined by analy=ing samples of air particulates, airborne iodine, milk, well water, vegetation and game.

Air particulate samples were collected weekly from seventeen locations (2B1, 6C1, 9C1, 1053, 1131, 13C1, 13H4, 1451, 15D1, 17B1, 20DI, 22G1, 26B1, 29B1, 31D1, 34S2, and 35B1). Airborne iodine samples were collected from eight locations (1053, 1131, 13C1, 13H4, 1451, 22G1, 31DI, and 35B1) and analy=ed for concentrations of I-131. Control locations were 13H4 and 22G1. Air particulate and airborne iodine samples were obtained using a vacuum sampler, glass fiber and charcoal filters, respectively. The filters were replaced weekly and sent to the laboratory for analysis. The vacuum samplers were run continuously at approximately I cubic foot per minute.

Milk samples were collected at fourteen locations (36E1, 5C1, 9E1, 9G1, 10B1, 10C1, 11D1, 11E1, 17C2, 17D1, 18C1, 21B1, 22F1, and 25B1). The collection frequency, as well as the dates when farms were discontinued or added to the program are described in the program History,Section III.C. Locations 9G1 and 22F1 were controls.

Samples were collected in new unused two gallon plastic bottles at each location, refrigerated, and shipped promptly to the laboratory. No preservative was added.

Well water samples were collected semi-annually from two locations 1151 (indicator) and 18A1 (control) in new unused two gallon plastic bottles. Vegetation samples composed of broad leafy vegetation and root crops were collected from one location (1151). During the preoperational period, the collection frequency was changed. A description of the changes is found in the Program History,Section III.C. A game sample was collected annually from one location (26S5) by hunting.

Ambient Gamma Radiation Direct radiation measurements were made using thermoluminescent dosimeters (TLD) consisting of calcium sulfate (CaSO4) doped with Thalium (Tm). The TLD locations were placed on and around the LGS site using a "three ring concept" consisting of:

A site boundary ring consisting of sixteen locations (36S1, 351, 551, 7S1, 1053, 1151, 1451, 1652, 1851, 2151, 23S2, 2551. 2653, 2951, 3251 and 3452) near and within the site perimeter representing fencepost doses (i.e., at locations where the doses will be greater than maximum annual off-site doses) from LGS releases A middle ring consisting of twenty seven locations (251, 2E1, 4E1, 6C1, 7E1, 9C1, 10E1, 10r3, 13C1, 13E1, ISD1, 16r1, 1781, 19DI, 20D1, 20T1, 24D1, 25D1, 26B1, 28D2, 2981, 29E1, 31D1, 31D2, 34E1, 35B1 and 35r1) extending to approximately 5 miles from the site designed to measure possible exposures to close-in populations f

And an outer ring consisting of five locations (5H1, 13H3, 18G1, 22G1 and 32G1) extending from approximately 12 to 30 miles from the site and considered to be unaffected by LGS releases. All forty-eight TLD locations were not in operation at the beginning of the preoperational period. The dates when additional TLD locations were added are found in the Program History,Section III.C.

The specific TLD locations were determined by the following criteria:

1. The presence of relatively dense populations

2. Site meteorological data taking into account distance and elevation for each of the 16 22-1/2 degree sectors around the site, where estimated annual dose from LGS, if any, would be most significants 6-

3. On hills free from local obstructions and within sight of the vents (where practical):

4. And near the closest dwelling to the vents in the prevailing downwind direction.

One TLD set - comprising four thermoluminescent dosimeters sealed in plastic to maintain integrity - was placed at each location in a pVC conduit located approximately three feet above ground level. The TLD set was exchanged monthly and sent to the laboratory for analysis.

B. Data Interpretation The radioanalytical and direct radiation data included in this report 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 undue repetition in the discussion of the results.

The minimum detectable level (MDL) was defined as the two sigma counting statistic. It represents the range of values into which 95% of repeated counts of the.same aliquot would fall. For all analyse .- (gross beta, I-131, H-3 and gamma) an activity that was greater than or equal to the MDL was reported as " activity plus/minus the MDL,value". For nongamma analyses (gross beta, I-131 and H-3) when an activity was less than tho M .7 L , the result was reported as the "< the MDL value". When,an; activity from a gamma isotopic analysis was less thal. the MDL value it uns reported as "< MDL" for the specific nuclide searched for unless a positive occurrence had been found in other samples. In t h~o s e cases the actual MDL ralues uere s 3isted.

The lower limit of detection (LI DL was defin'ed as the smyllest concentration of radioactive material in a sample that would yield a net count (above background) that would be' detected with only a 5% probability of falsely concluding Gas t a blank observation represents a "real" signal. .The' LLD was intended as a before the fact estimate of a system (including instrumentation, procedure and sample type) and not ns an after the fact criteria for the presence of actlElty. All analyses were designed to achieve the

~ required LGS detection capabilities for environmental sample sanhlysis. For a more detailed description oI the results

palculation, see Appendix D. s t k g

I l

Rasults for each type of sample were grouped according to the analyses performed. Means and standard deviations of these results were calculated. These standard deviations represent the variability of measured results for different samples rather than single analysis uncertainty. For these calculations, all results belou the MDL were considered to ,

be at the MDL. As a result, the means were biased high, and l the standard deviations were generally biased low. '

C. progrna History

< Radiation Management Corporation (RMC) was responsible for collection of all REMP samples with the exception of air particulate and air iodine samples from location 13H4, which was collected by PEco. For the time period 1 January 1982 through 30 June 1983, RMC was also responsible for the analysis and reporting of results for all REMp samples. Due to the acquisition of the RMC Laboratory facility by Teledyne Isotopes in 1983, the responsibility for the analysis and reporting of results was transferred to TI beginning 1 July 1983 and continued throughout the preoperational period.

Surface Water Surface unter samples were collected, composited, and analyzed in accordance with the sample collection program throughout the time period covered in this report. The five designated sampling locations did not change during this period.

Locations 24S1, 24S2, 16B2, and 10F2 were grab samples and 15F5 was a composite sample throughout 1982.

Collections for January through May of 1983 were comprised of grab samples from locations 24S2, 15B2, and 10F2 and composites from locations 24S1 and 15F5.

Beginning in June, 16B2 became a composite sample, '

leaving 24S2 and 10F2 as the only grab samples.

i Location 24S2 was changed to a composite sampie in July, 1983. Location 10F2 remained a grab sample through February 1984. In March, the location was changed to composite sampling; however, grab samples were taken in April through August, and again in November.

Samples from October and Movember, 1984 were composited for fourth quarter tritium analysis, the results of I which are included in this report.

All five dribNing water sampling locations (13H2, 15F4,

, 15F7, 16C2, 18F3) were composite samples throughout the preoperational period.

J As with surface water samples, the tritium composites forLthe last quarter of 1984 were comprised of October and November samples only.

Fish /

-4 Sediment

, Sediment samples lwere collected from three locations (16B2, 16C4 and 33A2). in accordance with the sample collection program throughout the preoperational period.

Air particulates The air particulate'po'rtion of the air sampling program tras started July 12,[1982, at ten locations (2B1, 6C1, 10S3, 1151, 13C1. 15D1, 17B1, 26B1, 29B1 and 34S2).

Seven of the seventeen locations were phased in after the original start-up date as follows:

Locations 9C1, 14S1, and 20D1 became operable on July 26, 1982.

Locations 22G1 and 31D1 became operable on August 16, 1982.

Location 13H4 bechne operable on November 10,1982.

L'ocation 35B1 became_ operable on January 30, 1984.

The first monthly' composite for gamma spec was comprised hof samples collected from August 30, through September

' 27, 19 8 ?. . The first monthly composites for locations 13H4 and 35B1 were collected in November, 1982 and ~

February, 1984, respectively.

Air Iodine The air iodine portion of the air sampling program was started in 1983. Location 13H4 had a start-up date of July 5, 1983.

Locations 10S3, 1151, 13C1, 14S1, 22G1 and 31D1 had a start-up date of September 5, 1983.

Location 35B1 became operable on February 6, 1984.

Milk In 1982, milk samples were collected for gamma spec and I-131 analysis from twelve farms on a quarterly schedule.

These farms were designated SC1, 9E1, 9G1, 10C1, 11E1, 17C2, 17D1, 18C1, 21B1, 22F1, 25B1, and 36E1. 17D1 was a goat farm. During the first half of 1983, each of the twelve farm locations was sampled in January, and again in May, representing the first\and second quarters of the year. During August and September, each location was sa.mpled once.

In October, 1983, a second goat farm, 10B1 was added to the program.

Bi-weekly collections at four farms (5C1, 10B1, 10C1, 22F1) were begun in October of 1983. This change in the program was for the purpose of increasing sample collections for I-131 analysis during the gracing season, April through November. Consequently, samples were taken from the four designated farms twice in October and November, but only once in December. The remaining eight farms were sampled once during all three months.

During 1984, samples were taken from all twelve farms monthly. In addition, the four designated farms were sampled bi-weekly during the grazing season.

In February, 1984, farm 17D1 was discontinued and removed from the program.

In August, 1984, farm 1001 was discontinued and farm 11D1 was added to the program. Additionally, farm 25B1 was added at that time to the group of farms scheduled for bi-weekly collection.

RESULTS AND DISCUSSION i

I i.-

IV. Results and Discussion A. Aquatic Environment

1. Surface Water Samples were collected from five locations monthly (10F2, 15F5, 16B2, 24S1, and 24S2). Of these locations, two (15F5 and 16B2) could be affected by Station discharge during operation. The following analyses were performed.

Gross Beta Samples from all locations were analy=ed for concentrations of gross beta in the soluble and insoluble fractions (Tables C-I.1, C-I.2, and C-I.5, and Figures C-1 and C-2, Appendix C). De te c tabl e activity was observed in both fractions ranging irom .6 to 15 pCi/1 in the soluble fraction and f r ota

<.2 to 22 pCi/1 in the insoluble fraction. The value of 15 pCi/l (24S1, December 1983) was due to an increase in dissolved solids at that location. The value of 22 pCi/1 (16B2, April 1984) was due to sediment in the sample from that location. A review of the insoluble data showed no differences between years; however, a statistical difference (p<.05) was observed between the indicator and control groups. The indicator locations had a group mean of .73 pCi/l while the control groups mean was .55 pci/1. The soluble data showed that the activity in 1984 was statistically higher (p<.05) than the other years. Ilowever, no differences were observed between indicator and control groups suggesting that the differences observed in the insoluble fraction were due to increased sediment in the samples from indicator locations.

Gamma Snectrometry Samples from all locations were analy=ed for gamma emitting nuclides (Tables C-I.2, C-I.4, and C-I.6, Appendix C). All nuclides searched for were below the minimum detectable level with the exception of naturally occurring K-40 at several locations over the three year period, ranging from 14 to 40 pCi/1, and one occurrence of Cs-137 (1.5 pCi/1, 24S2, August, 1983).

Tritium l Samples from locations 10F2, 16B2, and 2451 were analy=ed as quarterly composites for aqueous tritium activity (Table C-

I.1, C-I.3, and C-I.5, Appendix C). The data ranged from

<60 to 420 pCi/l over the three year period. The highest activities were observed from the second half of 1983 l through the end of 1984. The higher values were due to the change in analytical methods which occurred after the REMp was transferred to TI.

l l

2. Drinkina (potable) Water Monthly samples were taken from five locations (13H2, 15H4, 15F7, 16C2, and 28F3). Four locations (13H2, 15F4, 15F7 and 16C2) could be affected by Station discharge during operation. The following analyses were performed:

Gross Beta Samples from all locations were analyzed for concentrations of gross beta in the soluble and insoluble fractions (Tables C-II.1, C-II.3, and C-II.5, and Figures C-3 and C-4, Appendix C). The values ranged from .6 to 15 pCi/1 for the soluble fraction and from <.2 to 5.8 pCi/1 for the insoluble fraction. No significant difference in activity levels was observed between indicator and control locations for both the soluble and insoluble fractions. However, both fractions of the yearly data showed statistical differences (p<.05). The year 1984 was highest (E = .56 ins; 3.67 sol) and 1982 was lowest (E= .3 ins; 2.28 sol). Reviewing the combined 1982-1984 surface and drinking water soluble gross beta data indicated that the months of September, October, November, and August, respectively, showed a statistically higher activity (p<.05) than the other months. The higher activity values for these months may be the result of increased dissolved solids during those months (*3 Gamm'a Spectrometry Samples from all locations were analyzed for gamma emitting nuclides (Tables C-II.2, C-II.4, and C-II.6, Appendix C).

All nuclides searched for were below the minimum detectable level, except naturally occurring K-40, which uns de tected on four occasions throughout 1983 and 1984. The positive K-40 was detected in samples from locations 13H2 and 15F4 and ranged from 16 to 19 pCi/1. There was also one incidence of positive Cs-137 (1.0 pCi/1) at location 13H2, June, 1983.

Tritium Samples from locations 15F4, 16C2, and 28F3 were analyzed as quarterly composites for aqueous tritium activity (Table C-II.1, C-II.3, C-II.5, Appendix C). In 1982, no activity was observed in any of the samples analyzed. In 1983, samples from the same three locations were analyzed for tritium with Positive activity observed ranging from 150 to 320 pCi/1.

Beginning with third quarter 1984, location 15F7 was added to those samples receiving tritium analysis. positive tritium activity was observed in all samples, ranging from 90 to 400 pCi/1.

3. Fish Fish samples comprised of bullhead and redbreast /pumpkinseed were collected at three locations (16C5, 20S1 and 29C1) semi-annually . The following analysis was performed:

Gamma Spectrometry ,

The edible portion of fish samples from all three locations was analy=ed for gamma emitting nuclides (Tables C-III.1, C-III.2, and C-III.3 . Appendix C). The only nuclides detected were K-40 and Cs-137. Concentrations of K-40 ranged from 2.6 to 3.5 pCi/g (wet) for bullhead and from 1.3 to 4.3 PCi/g (wet) for redbreast /pumpkinseed. Cs-137, present due to previous weapons testing fallout, was found in one bullhead sample, .03 pCi/g (wet). All other nuclides were less than the minimum detectable level.

4. Sediment Aquatic sediment samples were collected at three locations (16B2, 16C4 and 33A2) semi-annually. The following analysis was performed:

Gamma Spectrometry Sediment samples from all three locations were analy=ed for gamma emitting nuclides (Tables C-IV.1, C-IV.2, and C-IV.3, Appendix C). Nuclides detected were Be-7, K-40, Cs-137, Ra-226, and Th-228/232. The nuclides K-40, Th-232/228, Ra-226, and Cs-137 commonly occur in sediment naturally, daughter decay from uranium, or from world-wide fallout.

, Concentrations of Be-7 were the result of cosmic ray activity.

1. Airborne

a. Air particulates continuous air particulate samples were collected from seventeen locations on a weekly basis. The seventeen locations are separated into three groups: Group I represents locations within the LGS site boundary (10S3, 1151, 14S1 and 3452), Group II represents locations near the LGS site (2B1, 6C1, 9C1, 13C1, 15D1, 17B1, 20D1, l 26B1, 29B1, 31D1, and 35B1), and Group III represents ,

control locations at remote distances from LGS (13H4 and j 22G1). The following analyses were performed: )

Gross Beta Weekly samples were analy=ed for concentrations of beta emitters (Tables C-V.1, C-V.2, C-V.3, C-V.7, C-V.8, C-V.9, C-V.13, C-V.14, C-V.15, and Figure C-5. Appendix C). Detectable activity was observed at all locations throughout the preoperational period, with only one sample in 1983, and two samples in 1984 having a less than MDL value. The activities ranged from <.003 to .25 pCi/m3 In 1982, there was a statistical difference (p<.05) between the activities of indicator and control locations. However 1982 was only a partial year (July-December); as a result, seasonal variability could account for the difference between data. Months (1982-1984 years combined) with the lowest activity were April, March, and May, respectively, and were stastically different (p<.05) from the highest month of September. The data also showed that indicator Groups I and II had a slight but stastically higher (p<.05) activity than control Group III. The high activity of

.25 pCi/m3 (17B1, 9/7/84-9/10/84) is attributable to a small sample volume (117.2m3) caused by a shortened sampling period.

Gamma Spectrometry Weekly samples were composited monthly and analy=ed for gamma emitting nuclides (Tables C-V.4, C-V.5, C-V.6, C-V.10, C-V.11, X-V.12, C-V.16, C-V.17, and C-V.18, Appendix C). Naturally occurring Be-7 was detected in all but six samples over the three year period, due to cosmic ray activity. These values ranged from <.02 to

.25 pCi/m3 K-40, was found in 39 of 467 samples analy=ed throughout the preoperational period, with values ranging from <.01 to .24 pCi/m3 In 1984, Th-228 was detected in 2 of 186 samples (.007 pCi/m3, 6C1, February 1984 and .010 pCi/m3, 29B1, February 1984). K-40 and Th-228 are also naturally occurring nuclides.

Cs-137 was detected in one sample during the preoperational period (.001 pCi/m3, 26B1, June, 1983).

b. Airborne Iodine Continuous air samples were collected from eight locations, (10S3, 11S1, 13C1, 13H4, 14S1, 22G1, 31D1, 35B1) and were analy=ed weekly for I-131. Results of the I-131 analysis are found in Table C-VI.1 and C-VI.2, Appendix C. All results were less than the minimum detectable level. l l

2. Terrestrial

a. Milk Milk was sampled from twelve locations throughout the preoperational period. The variations in the sampling schedule are described in the program History,Section III.C. The following analyses were performed:

Iodind-131 Milk from all locations was analyzed for concentrations of I-131 (Tables C-VII.1, C-VII.3, and C-V.5, Appendix C). All results throughout the preoperational period were less than the minimum detectable level.

Gamma Spectrometry Milk from all locations was analyzed for concentrations of gamma emitting nuclides (Table C-VII.2, C-VII.4, and C-VII.6, Appendix C). Nuclides detected were K-40 which is naturally occurring and Cs-137. The values ranged from 770 to 1900 pci/1 for K-40 and from .7 to 11 pCi/1 for Cs-137. All other nuclides searched for were less than the minimum detectable level.

b. Well Water Samples were collected from two locations semi-annually.

The following analyses were performed:

Tritium Total samples from both locations were analyzed for 2 aqueous tritium activity (Table C-VIII.1, Appendix C).

The results of samples analyzed in 1982 and 1983 from both locations were all below the minimum detectable level. In 1984, one sample from location 1151 and both samples from 18A1 had positive tritium results. These positive values could be due to the change in analytical procedure that took place at the end of 1983. j l

collection schedule is described in the Program History,Section III.C. The following analysis was performed:

Gamma Spectrometry Vegetation samples were analyzed for gamma emitting nuclides (Tables C-IX.1 and C-IX.2, Appendix C). The nuclides detected were naturally occurring Be-7 ranging from <.02 to .16 pCi/g (wet) and K-40 ranging from .77 to 6.1 pCi/g (Wet). Be-7 is due to cosmic ray activity. All other nuclides were less than the minimum detectable level.

I d. Game A rabbit sample was collected annually from one location (26S5) throughout the preoperational period. The following analysis was performed:

Gamma Spectrometry Rabbit flesh was analyzed for gamma emitting nuclides

( 7'able C-X .1, Appendix C). All nuclides searched for were less than the minimum detectable level with the exception of naturally occurring K-40, ranging from 2.7 to 3.6 pCi/ gram (Wet).

C. Ambient Gamma Radiation Ambient gamma radiation levels were measured utilizing CaSO:

Tm thermolumiescent dosimeters. Forty-eight TLD locations were established around the site in a three ring concept forcomparison purposest an " inner ring"of sixteen locations around the site boundary; a " middle ring" of twenty-seven locations within a ten mile radius of the site; and an " outer ring" of five locations at distances outside the ten mile radius ofthe site. Results of TLD measurements are listed in Tables C-XI.1, C-XI.2, C-XI.3, and C-XI.4 and Figure C-6, Appendix C. The initial results from October 1984 (published in reference 3) showed abnormally high ambient gamma radiation levels and large error terms. An investigation and subsequent recalibration of these TLDs resulted in the results presented in this report.The majority of all TLD measurements were below 10 mrad /std. month, with a range of 2.94 to 13.80 mrads/std.

month. The locations with the highest TLD results were 31D1, SH1, and 1151, respectively. An analysis of the data showed that the inner ring locations had an average ambient gamma radiation level that was statistically lower (p<.05) than the middle and outer ring locations.

• Tor typical minimum detectabl1 levels of nuclides searched for and not found, see Table C-XIII.1.

• • Th-232 and Th-228 are in the natural. radioactive thorium series and are presumably in equilibrium. Th-232, though not a gamma emitter, was the listed nuclide by RMC.

Tcledyne Isotopes lists Th-228 by measuring one of the several short-lived gamma emitting daughter products.

Also included in this section are descriptions of the analytical procedures and calculation methods used by Teledyne Isotopes for sample analysis from July 1983 through November 1984.

Sample preparation and Countina procedures several types of liquid samples are separated by filtration prior to analysis. Resulting portions are identified as soluble and insoluble. Therefore, soluble as used in this report, is defined as that portion of a sample that passes through a 450 Whatman filter paper. Insoluble is defined as that portion of a sample that is collected on 850 Whatman filter paper, i

GROSS BETA ANALYSIS OF SAMPLES (RMC) )

Insoluble Traction of Water (B4)

A 1000 ml aliquot of the sample is filtered through Whatman 850 filter paper. The filter paper is ashed in a preignited and Preweighed 2" x,1/4" ringed planchet and reweighed. The planchet is counted in a low-background gas-flow proportional counter. Self-obsorption corrections are made based on measured sample weight and calculated thickness. Sr-90-Y-90 is used as the calibration standard.

A clean, unused filter paper is processed in the same manner and used es a blank.

Soluble Traction of Water (56)

The filtrate obtained during procedure B4 is evaporated to dryness in a preignited and preweighed 2" x 1/4" ringed planchet and reweighed. The planchet is counted in a low-background gas flow proportional counter. Self-absorption corrections are made based on censured sample' weight and calculated thickness. St-90-Y-90 is used cs calibration standard. An aliquot of distilled water is evaporated in the same manner and used as a blank.

DETERMINATION OT GROSS ALPHA AND/OR BETA ACTIVITY IM WATER SAMPLES AIR PARTICULATE FILTERS, OR SEDIMENT (TI)

This describes the process used to measure the overall alpha and/or boto radioactivity of water samples, air particulate filters, composited oir particulate filters or sediment without identifying the radioactive One

, apacies present. No chemical separation techniques are involved.

litor of the water sample is evaporated on a hot plate. The evaporated oceple is rinsed into a 2-inch diameter stainless steel planchet which is otecpled with a concentric ring pattern to distribute residue evenly.

Final evaporation to dryness takes place under heut lamps. Residue mass io determined by weighing the planchet before and after mounting the acople. In the case of air particulate sample, the filter is mounted diroctly on a 2-inch steinless steel planchet. Sediment samples are driod and a 1 gram aliquot is mounted directly on a 2-inch stainless otool planchet.

The planchets are then counted for a alpha and/or beta activity in a low-background gas flow proportional counter. Calculation of activity includes an empirical self-absortion correction curve which allow for the change in effective counting efficiency caused by the residue mass. Self obcorption is not considered in the case of air particulate filters bacouse of the impracticality of accurately wieghing the deposit and boccuse the penetration depth of the deposit into the filter is unknown.

A 15 ml aliquot of the sample is vacuum distilled to eliminate dissolved gases and non-volatile matter. The distillate is fro =en it.

a trap cooled with a dry ice-isopropanol mixture. Eight (8) al of the distillate are mixed with ten (10) al 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 i

samples. In the calculation of the result it is assumed that the

, condensed and original sample are of equivalent volumes. The volume change associated with the renoval of dissolved gases and non-volatile matter is not significant compared to the other errors in the analysis.

ANALYSIS OF SAMPLES FOR I-131 (RMC)

Milk (10)

The initial stable iodide concentration in milk is determined with cn icdide specific electrode. Three mill 111ters of stable iodide c u rior is then added to four (4) liters of milk. The iodide is romovad from the milk by passage through an ion-exchange resin. The iodido is eluted from the resin with sodium hypochlorite, and purified by o ceries of solvent extractions with the final extraction into a toluone phase. The toluene phase is mixed with a toluene-based liquid scintillation solution. The rample is then counted in a beta-gated g0223 coincidence detector shielded by six inches of steel. Distilled unter is used as a blank. The yield is calculated from stable iodide rocov0ry based on the recovered volume. Results are corrected for daccy from the sampling time to the middle of the counting period uaing a half-life value for I-131 of 8.06 days.

Calculation of results and two sigma error The spectrum obtained is smoothed to minim 1=e the effects of rcndca statistical fluctuations. The presence of Iodine-131 is id0ntified by the presence of a 364 MeV peak. The not area above the b;soline is calculated. This counting rate is converted to activity (pci) for units volume making allowance for counting efficiency and gcCC3 ray abundance.

DETERMINATION Or I-131 IN MILK AND WATER SAMPLES BY RADI0 CHEMISTRY AND LISUID PHASE BY ANALYSIS I

(TI) l This describes the radiochemical methods for determining I-131 cet{vity in milk and water samples by cof ,nidence counting in the liquid phase.

Four liters of sample are first equilibrated with stable iodide carrier. A batch troatment with anion exchange resin is used to remove iodide from the sample. The iodine is then stripped from the resin with sodium hypochlorite solution, reduced with hydroxylamine hydrochloride, and extracted into carbon tetrachloride cc free iodine. It is then back-extracted as iodide into sodium bisulfite solution.

The iodide sample solution is oxidized to the free state using NCNog reagent and is extracted several times into a total of 15 al of toluene. A 200 pl aliquot is taken for determining chemical yield by spectrophotometer. A decolori=ing agent (2-methyl-2-butene) is added to the toluene-iodine solution to form an inert molecule and to cinimi=e liquid scintillation quenching. A toluene-based liquid ceintillation counting solution is added to the sample, uhich is then cnalyzed by a beta-gated gamma-coincidence counting system.

Consequently, the branching intensity (abundance) of the I-131 gamma does not appear in the above equation.

Calculation of the MDL If the net activity (previously defined) is equel to or is less than a specified multiple of the background counting error, the cativity on the collection date is below the limits of detection and 10 called "less than" (L.T.) or " minimum detectable level" (MDL).

The L.T. value can be specified by stating only the counting error et c predetermined multiple (am) of the one sigma statistics. A sigma cultiple (s m ) of 4.66 is used for eniculation of the L.T. values unloss another multiple such as 2.83 is specified.

DETERMINATI0M Of GAMMA EMITTING RADIOISOTOPES (TI)

Gamma emitting radioisotopes are determined with the use of a lithium-drifted germanium (Ge(Li)) and high purity germanium detectors with high resolution spectrometry in specific media, for example, air particulate filters, charcoal filters, milk. water, vegetation, soil / sediments, biological media, etc. Each sample to be assayed is prepared and counted in standard geometries such as one liter wrap-around Marinelli containers, 300 ml or 150 ml bottles, or two-inch filter paper source geometries.

Samples are counted on large (>55 cc volume) Ge(Li) detectors connected to multi-channel pulse height analy=ers and mini-computers for data acquisition and computations. All resultant spectra are stored on magnetic tape.

The analysis of each sample consists of calculating the specific activities of all detected radionuclides or the detection limits from a standard list of sixteen nuclides. The Ge(Li) systems are calibrated for each standard geometry using certified radionuclide standards from Amersham /Searle and the National Bureau of Standards.

ENVIRONMENTAL D05IMETRY (DO)

(RMC and TI) l A thermoluminescent dosimeter (TLD) is considered to be one end of o capillary tube containing calcium sulfate (Tm) powder as the thermoluminescent 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 chield supplied by panasonic Corporation, manufacturer of the TLD reader. There exist four dosimeters per station sealed in a l

i polyethylene bag to demonstrate integrity at the time of measurement, cnd for visualization of the sample placement instructions. The zero dose is determined from TLDs located in the lead shield found at RMC, philadelphia from January 1982 through June 1983 and at Teledyne Isotopes in Westwood. Hou Jersey from July 1, 1983 through the and of the preoperational period.

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

Data are normalized to standard instrument conditions by adjusting cachine settings to designated values before readout. Data are also corrected for in-transit dose using a set of TLDs kept in a lead chield in the field, exposed only during transit. The average dose per exposure period and its associated error is then calculated.

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

1982 NOTES:

(A) EPA Results - Expected laboratory precision (1 sigma). Units are in pC1/f for water, urine, and allk except K which is in ag/f. Units are in total pCi for air particulate filters.

(8) Radiation' Management Corporation's Results - Average i I sigma. Units are in pCi/f for water, urine and milk except K which is in mg/f. Units are in total pCl for air particulate filters.

(C) Units for food analyses are in pClikg.

(D) Insufficient sample to reanalyre. Probable reasons for discrepancy are incomplete transfer of sample to planchet, incorrect pipetting of sample aliquot and nonhomogeneity of sample.

(E) Calculation was verified. Sample could not be reanalyzed because it was destroyed in the strontium analysis. Gross alpha, gamma and strontium-90 for that sample were in agreement with the EPA.

(F) Positive activity was not detected due to the low sensitivity of the analysis for Ru-106.

(G) Positive activity was not detected due to the low sensitivity of the analysis for Cr-$1.

(H) A new strontium procedure was introduced in March 1982. These intercomparison samples 1 were analyzed during the testing stage and showed the need for retraining in separation technique.

• Represents samples analyzed by RMC, others at Teledyne Isotopes.

(F) In order to improve the results for Ra-226 a new standard was ordered and the efficiency calibration of the alpha counter was checked. For Ra-228 the results are being counted at both the high and low beta-gamma energy regions of the daughter product Ac-228 in order to have two measures of the Ra-228 activity.

(G) Two of the three samples analyzed for 2n-65 were within the 2 sigma limits. One sample showed high results which may have been due to a low count time.

1 Notes:

(A) EPA Results-Empected laboratory precision (3 sigma). Units are in pct /f for water, urine. and milk except K which is in mg/f. Units are in total pCi for air particulate filters.

(B) Teledyne Results - Average i three sigma. Units are in pCi/f for water.

urine, and milk except K which is in mg/l. Units are in total pCi for air particulate filters.

(C) Units for food analyses are in pC1/kg.

(D) Results were not released at time of report.

(E) No action was considered necessary as the tritium results are usually accurate.

(F) Teledyne Isotopes is now using the same conversion factor that the EPA uses to convert pC1/ liter of K-40 to mg/ liter of K.

(G) There was a high decay factor due to a delay in receipt of sample after collection. 5tnce results are generally accurate for I-131, no further action was planned.
