SUMMARY
AND CONCLUSIONS This report on the radiological environmental monitoring program conducted at the Peach Bottom Atomic Power Station for Philadelphia Electric canpany by Teledyne Isotopes covers the period January 1,1983 to December 31, 1983.
During this period 4558 analyses were performed on 3924 sanples.
Surf ace water and discharge water sanples were analyzed for concentrations of tritium, gross beta, and gamma-enitting nuclides. Surface water was also analyzed for concentrations of gross alpha.
Comparisons of unaffected stations with potentially affected stations, in Conowingo Pond, showed no significant difference in concentrations of the radionuclides studied.
It was shown that no significant differences existed between the preopera-tional and operational periods; therefore, it can be concluded that the levels of radioactivity in Conowingo Pond water have not been measurably influenced by the operation of the Peach Bottom Atomic Power Station.
High sensitivity 1-131 analyses were performed on weekly air sanples.
All results were less than the minimum detectable level.
High sensitivity 1-131 analyses were also performed on weekly milk samples while cows were on pasture and on monthly samples when cows were not grazing. Milk collected from stations A, C, and G showed positive results on March 25, 1983, which was attributed to PBAPS operations.
The maximum hypothetical dose is calculated to be 0.4 mrem to an infant's thyroid.
I Soil sanples were analyzed for concentrations of Sr-89, Sr-90 and gamma-enitting nuclides. The levels observed were not significantly different from preoperational data.
Environmental gamma radiation measurements were made using thermolumi-nescent dosimeters. Results from the site-boundary, middle and outer rings were found to be not significantly different, so it can be concluded that the operation of Peach Bottom Atomic Power Station did not produce measurable levels of anbient gamma radiation at any off-site location.
In assessing all the data gathered for this report and comparing the results with preoperational data, it was evident that the operation of the Peach Bottom Atomic Power Station resulted in no significant radio-logical impact on the environment.

INTRODUCTION
II.
INTRODUCTION Teledyne Isotopes (TI) began conducting a radiological environmental monitoring program in July 1983 for the Philadelphia Electric Company in connection with the Peach Bottom Atomic Power Station (PBAPS) located in Peach Bottom Township, York County, Pennsylvania. TI replaced Radiation Management Corporation (RMC) when the analytical laboratory was aquired by TI.
This report, therefore, covers the entire 1983 year, including those results generated by both TI and RMC.
In order to maintain the integrity and consistency of the monitoring program, all records and most equipment were transferred from RMC to TI.
In addition, a six-month overlap period existed, during which close contact between TI and RMC personnel was maintained. RMC's analytical procedures were reviewed and where appropriate, adopted by TI. Finally, in July all activities were transferred to TI.
This TI program complements an existing program being conducted by others which has been carried out since March 1960. PBAPS is located along the Susquehanna River between Holtwood and Conowingo Dams.
The fourteen mile long pond created by Conowingo Dam is called Conowingo Pond.
The initial loading of fuel into Peach Bottom Unit No.1, a 40 MWe (Net) high temperature gas-cooled reactor, was started on February 5,1966, and initial criticality was achieved March 3,1966.
Final shutdown of Peach Bottom Unit No I was on October 31, 1974. Peach Bottom Unit No. 2 and No. 3 are boiling water reactors each with a power output of approxi-mately 1050 MWe (Net).
The first fuel was loaded into Unit No. 2 on August 9,1973, and criticality was first achieved on September 16, 1973.
The fuel was loaded into Unit No. 3 on July 5,1974 and critic-ality was first achieved on August 7,1974. Peach Bottom Unit No. 2 first reached full power on June 16, 1974. Peach Bottom Unit No. 3 first reached full power on December 21, 1974.
A special preoperational report (1) for Peach Bottom Units No. 2 and No.
3 has been issued previously which stamarizes results of all analyses performed on samples collected from Septaber,1970 through August 8, 1973, the day before fuel was first loaded into Peach Bottom Unit No. 2.
This report contains data for samples representing the period January 1, 1983 through December 31, 1983.

SAMPLE COLLECTION AND TLD PLACEMENT PROCEDURES l
l The program being conducted by TI is described in Tables I and II and Figures 1-3.
1.
Sample Collection a.
Water (except precipitation)
All samples were collected in new polyethylene bottles. All persons involved in sample collection and handling were ad-vised not to wear luminous dial watches in order to avoid possible cross contamination from that source. Sample containers were rinsed at least twice with the water to be sampled before collection.
All water samples were grab samples except those collected at stations ILL, IMM, 61 and 4L. Weekly samples were taken from a tank which continually collects a sample at these four locations.
The weekly samples were composited into a monthly sample for analysis.
Collection methods are de-scribed in more detail in Table II,Section V.
b.
Precipitation Precipitation was collected in an apparatus consisting of a new polyethylene bottle with a plastic funnel 8 inches in di ameter.
The bottle was replaced monthly and the sample bottle was shipped to TI for analysis.
The amount of pre-cipitation was recorded continuously by a separate rain gauge at station IA.
c.
AIR PARTICULATES Air particulate samples were obtained using a vacuun sampler and glass fiber filters, approximately 2" in diameter.
The filter was replaced weekly and sent to TI for analysis.
The vacuun sampler was run continuously at approximately 1 cubic foot per minute.
d.
AIR IODINE Air iodine samples were obtained using a vacuan sampler and charcoal filters, aproximately 2 " in diameter. The filter was replaced weekly and sent to TI for analysis.
The vacuan sampler was run continuously at approximately 1 cubic foot per minute.
e.
MILK Milk samples were collected in new polyethylene bottle from the bulk tank at each farm, refrigerated and shipped immed-l iately. No preservative was added.
5
f.
Soil Soil samples consisting of seven cores, 2" in diameter and 6" deep were collected from a 50 X 50 f t. area at each sam-pling location. Top soil (upper 1 inch) and bottom soil (1cwer 5 inches) were separated, then sealed in separate plastic bags, and shipped to TI.
2.
TLD Placement A systs using thermolminescent dosimeters (TLDs) was used to measure the direct radiation levels in the PBAPS environment.
The TLD stations were placed on and around the Peach Bottom Site using the "three ring concept". Two on-site stations, designated as plant complex stations are not included in any of the three rings.
a.
A site boundary ring near and within the site perimeter, representing fencepost doses, i.e., at locations where the doses are greater than maximm annual off-site doses from Station releases; b.
A middle ring extending to approximately 10 miles from the Site, designed to measure possible exposures to close-in population; c.
An outer ring extending from approximately 10 to about 60 miles from the Site; and cor.sidered not to be affected by Station releans; d.
The specific location of each station was detennined by the following criteria:
(1) The presence of relatively densely populated areas; (2) From Site meteorological data taking into account distance and elevation for each of the 36 ten-degree sectors around the Site, where estimated annual dose from the Station, if any, would be more significant; (3) On hills and (where pratical) within sight of the stack, and free from local obstructions; (4) Near the closest house to the stack in the prevailing down wind direction.
~
e.
Each TLD set (4 TLDs pe* set) was placed in a sealed poly-ethylene package to verify the integrity of the dosimeters when collected. Two packages were kept in a locked formica
" birdhouse" or polyethylene jar, about six feet above the ground or supporting surface at each location. At each station one package was exchanged for measurment on a monthly schedule, and one on a quarterly schedule.

3.
The composite surface water sampler at station 6I malfunctioned from 07/02/83 to 07/09/83 and from 07/30/83 to 08/06/83, therefore, no sample was collected for I-131 analysis during July and August.
4.
No air particulate sample for gross beta analysis was collected from station 1Z from 02/05/83 to 02/13/83 due to sampler malfunc-tion.

6.
The charcoal filter collected from station 1B for the period 11/05/83 to 11/12/83 was not alalyzed due to low air volune.
7.
TLD data was unavailable from station 1M in July; from station 16 in April and May and from station 218 in February of 1983 due to vandalism of TLD's.
8.

IV. RESULTS AND DISCUSSION A.
DATA INTERPRETATION AND STATISTICAL ANALYSIS Several factors are important in the interpretation of the data.
In order to avoid undue repetition in the discussion which follows, these factors are described below.
1.
Grab Sat. ing Grab sampling is a useful and acceptable procedure for taking er,iironmental samples of a medium in which the concentration of radionuclides is expected to vary slowly with time or where intermittent sampling is desned sufficient to establish the radiologii:al characteristics of the medium.
This method, however, is only representative of the sampled medium for that specific location and instant of time. As a result, variation in the radionuclide concentrations of the samples will normally occur. Since these variations will tend to counterbal-ance one another, the extraction of averages based upon repetitive grab samples is valid.
2.
Minimum Detectable Levels (MDL)
It is characteristic of environmental monitoring data that i
many results occur at or below the specified detection levo s.
Formal statistical error analysis of groups of such data is difficult. Pragmatic approaches to the problen include counting the detection' level entries as zero, as half the detection level value, or as full detection level value. For reporting and calculation of averages in this report, any result occuring at or below the minimte detectable level is considered to be at that level. Averages obtained using this method are therefore biased high.
3.
Standard Deviation of Analytical Results Within the data tables an approximate 95 percent (2 sigma) confidence interve. is supplied for those data points at and above the minimun detectable level. These intervals represent the range of values into which 95 percent of repeated counts of the prepared sample would fall.
4.
Table Means and Standard Deviations Results for each type of sample were grouped according to the l
analysis 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 calcula-tions, all results below the MDL wer^ :onsidered to be at the MDL. As a result, the means are biasad high, and the standard deviations are biased low.
9
B.
DISCUSSION OF RESULTS Results are summarized in brief form in Tables.IV, V and VI (SectionV). Tables of results for individual sample types and analyses performed can be found in Section V, Tables VII to XXVI. Graphical presentations of results can be found in Section VI.
1.
Surface Water-Samples were taken from nine stations on a monthly schedule.
Three stations (ILL, 4L and 61) were continuous composite samples and five (1Q, 4F, 4G, 6A and 13A) were grab samples.
Station' 138 was sampled.a total of seven times in 1983. Of these stations, seven could be affected by released from Peach Bottom Atomic Power Station..The remaining stations (6A and 61) were above Holtwood Dam and, therefore, could not be
-l affected by plant discharges (refer to Figures 1 and 2,Section VI, for station locations). The following analyses were performed on surface water samples.
a.
Tritium Total samples' from seven stations were analyzed for concentra-tions of aqueou's tritium.
Samples from stations 1LL,.1Q,.4L and 61 were analyzed on a monthly basis, while samples from i
stations 4F, 6A and 13A were composited monthly into.a quarterly sample. Results of this analysis for surface water samples can be found in Tables VII and VIII,Section V.
The concentra-tions detected were within the range found during the Peach Bottom Units number 2 and number 3 preoperational period (1).
Graphical comparisons of the unaffected stations (6A and 61) above Holtwood Dam with potentially affected stations (4F and 4L) at Conowingo Dam showed no detectable addition of tritium to Conowingo Pond from the operation of PBAPS (Figures 4 and 5,.Section VI). Reported tritium concentrations generally increased from below minimum detectable level to approximately 150 pCi/A during the second half of the year. This increase is correllated with the change in the analytical laboratory and resulting change in procedure.
b.
Gross Alpha Samples from four stations (4F, 4L, 6A and 61) were analyzed for gross alpha concentrations in the soluble and insoluble fractions. Results of gross alpha analysis in surface water j
samples can be found in Tables VII and VIII,Section V.
Results at all locations were generally at or below the minimum detectable level in the soluble fraction. Results of the insoluble fraction were generally at or below the minimum.
detectable level at stations 4L, 6A and 6I, and detectable at low levels at station 4F. Those values were similar to those seen in
[
previous year's and can be attributed to the presence of sediment, a
~
reservoir of fallout and natural alpha emitters.

c.
Gross Beta
. Samples from all stations, were analyzed for concentrations of gross beta in the soluble and insoluble fractions.
Results of gross beta analysis in surface water sanples can be found in Tables VII, VIII and Section V.
The concentrations detected in the soluble and insoluble fractions were within the range observed during the preoperational period for Units nunber 2 and 3 (1). A graphical canparison of two Conowingo Dam stations (4F and 4G) with one Holtwood Dam station (6A) showed the results of the soluble and insoluble fractions to be generally the sane for all three locations (Figures 6 and 7,Section VI).
d.
Iodine-131 Samples collected during the last week of each month from 01/08/83 to 12/03/83 from two stations (4L and 61) were analyzed for concentrations of I-131. Results of I-131 analysis of surface water sanples can be found in Table VIII,Section V.
Almost all results were below the minimum detectable level. Jetectable concentrations were found at station 6I in February. The I-131 activity was attributed to upstream sources.
e.
Gamma Spectrometry Samples from all stations were analyzed for gamma-emitting nuclides by gamma spectrometry.
Results of gamma spectrometry on surface water sanples can be found in Table IX,Section V.
The nuclides searched for were below the minimum detectable level with the exception of K-40 which was found at three stations, 61, ILL and 4L.
2.
Discharge Water Sanples were taken from two stations (IM and IMM) on a monthly schedule (refer to Figure 1,Section VI, for station locations).
The following analyses were performed on discharge water samples, a.
Tritium Total sanples from both stations were analyzed for concentra-tions of aqueous tritium on a monthly basis. Results of tritium analysis in discharge water samples can be found in Table X and XI,Section V.
The concentrations detected were 1
11
= within the range found.during the Peach Bottom Units nunbers 2 and 3 preoperational period (1). Reported tritium concentrations generally increased from below minimun~ detectable level to approxi-mately 200 pCi/E during the second half of the year.
This increase is correllated with the change in analytical laboratory and resulting change in procedure. A graphical comparison of concentrations of aqueous tritium results for composite surface water-and discharge water samples showed no significant differences (Figure 8, Section E
VI).
b.
Gross Beta Monthly samples from both stations were analyzed for gross beta concentrations in the soluble and insoluble fractions.
Results of these analyses.in discharge water samples can be found.in Tables X and XI,Section V.
The concentrations -
detected in the soluble and insoluble fractions were similar to those observed in surface water samples (Figures 9 and 10, SectionVI).
c.
Gamma Spectrometry l
Samples from both stations were analyzed for gamma-emitting nuclides by spectrometry. Results of gamma spectrometric analysis are given in Table XII,Section V.
Low conce_ntrations of Co-58 and Mn-54 were found at station 1M in February and K-40 was.found at Station 1MM in July.
In all other samples all nuclides searched for were below the MDL.
3.
Well Water Samples were taken from four stations on a quarterly schedule. Two stations (1U and IV) were located within the Site area. The other stations were located approximately one mile (Station 40) and 10 miles (station 7) from the Plant. These station locations are shown in Figures 1 and 2,Section VI.
The following analyses were performed on well water samples.
a.-
Tritiun Total samples from all four stations were analyzed for aqueous tritium concentrations.
Results of tritiun analysis of well water samples can be found in Table XIII,Section V.
Results of all samples were within the range found during the Peach Bottom Units numbers 2 and 3 preoperational period (1). Reported tritium-concentrations generally increased from below minimun detectable level to approximately 200 pCi/f during the second half of the year.
This increase is correllated with the change in analytical laboratory and resulting change in procedure. A graphical comparison of the 7
i distant site-area, and on-site wells showed that tritiun levels have been gradulally decreasing with time due to the cessation of routine i
atmospheric nuclear weapons testing (Figure 11,Section VI).

b.
tiross Beta-Samples from all four stations were analyzed for gross beta concentrations in the soluble and insoluble fractions.
Results of gross beta analysis on well water samples can be found in Table XIII,Section V.
The concentrations detected were within the range observed during the Peach Bottom Units numbers 2 and 3 preoperational period (1).
4.
Precipitation Precipitation was collected from two stations on a monthly schedule. Station 1A is located at the on-site Peach Bottom Weather Station nurnber 1.
Station 8, located in Colora, Md.,
is approximately 10 miles from the Site (for station locations, refer to Figures 1 and 2,Section VI).
The following analyses were performed on precipitation samples.
a.
Gross Beta Monthly samples were analyzed for gross beta concentrations in the total sample. Results of gross beta analysis in precipita-tion samples can be found in Table XIV,Section V.
Concentra-tions detected were within the range found during the Peach Bottom Units 2 and 3 preoperational period (1).
b.
Gamma Spectrometry Monthly samples were analyzed for gamma-emitting nuclides by spectrometry of the total sample.
Results of gamma spectrometric analysis of samples from both stations are given in Table XV,Section V.
Be-7 was found in eleven of twenty-four samples and can be attributed to cosmic ray activity. K-40 was found at station 8 in August and was within the range of other MDL values observed.
5.
Air Particulates Continuous air particulate samples were collected from the on-site Peach Bottom Weather Station number 1 (1Z) and from the intermediate location, Conowingo Dam (4A) (For station locations, see Figure 1 and 2, section VI).
The following analyses were performed on air particulate samples, a.
Gross Beta Weekly samples were analyzed for concentrations of beta emitters.
Results of gross beta analysis of air particulate samples can be found in Table XVI, Section v.
Results observed were similar to i
levels observed in previous years.
13
b.
Gamma Spectrometry Monthly composite samples were analyzed f]r gamma-emitting nuclides by gamma spectrometry.
Results of gamma spectrometric analysis are given in Table XVII,Section V.
Be-7 was detected in all of the samples and was the result of cosmic ray activity.
Naturally occuring X-40 was found in-1 of 24 samples. All other nuclides searched for were below the minimun detectable levels.
6.
Air Iodine Continuous air samples were collected at eight stations and analyzed weekly for I-131.
Three stations (1B, 1Z, 2) were located within the Site area.
Four stations (3A, 5, 68,14) were located at intermediate distances of 1.9 to 5.8 miles from the site. One station (12D) was located 62 miles from the Site. Results of I-131 analysis can be found in Table XVIII,Section V.
All results of the 406 analyses performed were less than the minimun detectable level.
7.
Milk Milk was sampled at eleven farms; three farms (G, J and 0) located within two miles of PBAPS were designated "near farms"; four farms (D, L, M and N) located 3 to 5 miles from PBAPS were designated as " intermediate farms"; and four farms (A, 8, C and E) located greater than five miles from PBAPS were designated as " distant farms". The following analyses were performed on milk samples.
a.
Tritium Milk from four fanns (A, C, G and J) was analyzed for tritium concentrations in the aqueous fraction on a quarterly basis.
Results of tritium determinations in milk samples can be found in Table XIX,Section V.
Concentrations detected were within l
the range found during the Peach Bottom Units nunbers 2 and 3 peroperational period (1)
Reported tritium concentrations i
generally increased from approximately 115 pCi/E to approximately l
140 pCi/E during the second half of the year.
This increase l
is correllated with the change in analytical laboratory and j
resulting change in procedure.
b.
Iodine-131 Milk from eight farms ( A, B, C, D, G, J, N and 0) near Peach Bottom was analyzed for concentrations of I-131, monthly in January, February, March and December. Weekly I-131 analyses resuned during the first week of April and continued through 14
tha third w:ek of Nsvember. Three additional farms (L, M and
'E) were sampled and analyzed quarterly for I-131. Results of I-131 analysis can be found in Tables XIX and XX, Section.V and Figure 12,Section VI. Samples collected from three stations A, C and G on March 25, 1983 showed detectable levels of.07i.03,
.6t.1 and 4.41.4, respectively. This activity can be correllated with slightly increased I-131 increases from PBAPS during March.
The maximum hypothetical dose to an infant's. thyroid was calculated to be 0.4 mrem. This calculation was done using the assumptions of USNRC Regulatory Guide 1.109, Revision 1, October 1977.
c.
Strontium-89 and Strontium-90 One milk sample was collected at farm J in each quarter and analyzed for Sr-89 and Sr.-90.
Results can be found in Table XXI,Section V. All Sr-89 results were less than the minimum detectable level.
Sr-90 concentrations were similar to those observed in previous years.
d.
Gamma Spectrometry One milk sample collected at farm J in each quarter was analyzed for gamma-emitting nuclides by gamma spectrometry.
Results can be found in Table XXI,Section V.
Nuclides detected were naturally-occuring K-40 and Cs-137. Cesium-137 is comonly found in milk as a result of world-wide fallout.
Concentrctions were similar to those ciserved in previous years.
8.
Soil Semiannual samples were taken at three locations, one on-site station (2) and two distant stations (3A and 5) located about four miles from PBAPS (for station locations, see Figures 1 and 2,Section VI). The area at station 2 is heavily wooded with rock outcroppings. The soil at this location would be expected to contain substantial humus from the accumulation of natural vegetative debris. Station 3A is covered only with grass. Station 5 is a combination of grass and cultivated land. The following analyses were performed on soil samples.
a.
Strontium-89 and Strontium-90 Samples from all stations were analyzed for Sr-89 and Sr-90 concentrations in the top one inch and bottom five inches separately. Results of Sr-89 and Sr-90 analysis in soil samples can be found in Table XXII,Section V.
Concentrations of Sr-89 were less than the minimum detectable level in all 15
~.
"r I
samples. Concentrations of Sr-90 detected ware within the range found during the PBAPS Units'nurnbers 2 and 3 preoperational pariod (1).. Graphical comparisons of Sr-90 in the top' one inch
- and bottom cut can be found in Figures 13 and 14,Section VI.
Differences between the on-site location (2) and distant locations (3A and ~ 5). were attributed to the accumulation of vegeta-tive debris at station'2.
b.
Gamma Spectrometry-Samples from all stations were analyzed for gamma-emittina nuclides by Ge(Li) gammaispectrometry (Table XXII,Section V).
- Nuclides identified.w'ere generally the same 'as those found during
. the PBAPS Units. numbers 2 and 3 preoperational period with most at i
the same or lower concentrations (1). Some naturally-occurring nuclides were found (K-40, Ra-226, Be-7 and Th-228/232. Small concentrations of.Cs-137 were detected in all. twelve samples and-were similar to levels observed in previous years.
The 30 year half-life.and biological assimilation of Cs-137 accounts for the continued appearance of.this nuclide in soil samples many years after atmospheric testing of nuclear weapons.
There was.little i
difference between the on-site location (2) and distant. locations (3A and 5) (Figures 15 and 16,Section VI). _ The concentrations of
- other nuclides detected were similar to levels observed in previous years.
9.
Ambient Gamma Radiation Ambient gamma radiation levels were measured with calcium sulfate: Tm thermoltsninescent dosimeters.
l Thirteen stations (18,1C,1D, IE, IF,.1G,1H, IJ, IL, IM,1NN, 2 f
and 40) were located around the Site boundary and designated for comparison purposes as the " site boundary ring".
Twenty-five i
stations (3A,4K,5,68,14,15,17,22,23,26,27,31,32,33A, 38, 42, 43, 44, 45, 46, 47, 48, 49, 50 and 51) were located within a
. 10 mile radius of the Site and. designated as the " middle ring".
Seven stations (128,16,18,19, 20, 21B and 24) were located from 10 to 60 miles from the Site and designated as the " outer ring".
Since they could be more directly affected by Plant activities and do not represent doses to the public, two stations (1A and -11) located within the plant complex constitute a fourth group called-plant-complex station (for station locations, see Figures 1, 2 and 3,SectionVI). Results of TLD measurements are listed in Tables XXIII, XXIV and XXV,Section V.
TLD readings of greater than 10 mrad /std. month were observed..in January, February and March at Station IL-(located at the Plant Water Intake).1This trend was also noted in the first quarterly result. An investigation showed that radiography tests were being performed near Station il during this
- time peridd.
16 i.
_ _. _ _.,. ~ _ _
Erratic TLD readings were observed from many Stations in July, (Table XXIII). The ' values ranged from 1.43 to 19.95 mrad /std. month.
New personnel processed the TLD's in July; however a laboratory investiga-tion could not determine any reason for the anomalies.
The annual average of monthly and quarterly radiation levels were within the range found during the Peach Bottom Units nunbers 2 and 3 preoperational period (1). Graphical comparisons of the site-boundary, middle and outer rings on monthly and quarterly readings showed no significant differences in ambient radiation levels with distance from PBAPS, indicating no measurable Station contribution (Table XXV,Section V, Figures 17 and 18, section VI).

SYN 0PSIS OF ANALYTICAL PROCEDURES
SYN 0PSIS OF ANALYTICAL PROCEDURES In the-following section there is a description of the analytical laboratory procedures used along with an explanation of the analytical calculation methods. The first part consists of the procedures that were followed in Philadelphia (RMC). The second part consists of-those procedures followed in Westwood (TI).
Sample Preparation and Counting 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 No. 50 Whatman filter paper.
Insoluble is defined as that portion of a sample that is collected on No. 50 Whatman filter paper.
i GROSS BETA ANALYSIS OF SAMPLES ( ANALYZED BY RMC)
Insoluble Fraction of Water (84)
A 1000 ml aliquot of the sample is filtered through Whatman No. 50 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-absorption 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 as a blank.
Soluble Fraction of Water (86)
The filtrate obtained during procedure B4 is evaporated to dryness in a preweighed, 2" x 1/4" ringed planchet and reweighed.
The planchet is counted in a low-background gas-flow proportional counter. Self-absorp-tion corrections are made based on measured sample weight and calculated thickness.
Sr-90-Y-90 is used as calibration standard. An aliquot of distilled water is evaporated in the same manner and used as a blank.

I ANALYSIS OF SAMPLE FOR TRITIUM (ANALYZED BY RMC)
Water (H2)
A 15 ml aliquot of the sample is vacuum distilled to eliminate dissolved gases and non-volatile matter. The distillate is frozen in a trap cooled
.with a dry ice-isopropanol 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/t) 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 condensed 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.
Milk (H3)
A 100 ml aliquot of sample is dried in a rotating vacuum flash evaporator.
During the evaporation process, the evaporated water fraction is trapped out by a dry ice-isopropanol mixture for counting. Approximately 20 ml of condensate is vacuum distilled to elimin te dissolved gasses and non-vola-tile matter. Counting is the same as for water above.

ANALYSIS OF SAMPLES FOR I-131 (ANALYZED BY RMC)
Milk (10)
The initial stable iodide concentration in inik is determined with an iodide specific electrode. Three milliliters of stable iodide carrier is then added to
=four (4) liters of milk. The iodide is removed from the milk by passage through an ion-exchange resin. The iodide is eluted from the resin viith sodium hypochlor-ite, and purified by a series of solvent extractions with the final extraction into a toluene phase.
'.he toluene phase is mixed with a toluene-base'd liquid scintillation solution. The sample is then counted in a beta-gated gamma coinci.dence 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.
Calculation of results and two sigma error:
The spectrum obtained is smoothed to minimize the effects of random statistical fluctuations. The presence of Iodine-131 is identified by the presence of a 364 kev peak.
The net area above the baseline is calculated. This counting rate is converted to activity (pCi) for units volume making allowance for counting efficiency and gamma ray abundance.

STRONTIUM-89 AND STRONTIUM-90 ANALYSIS OF SAMPLES (ANALYZED BY RMC)
Milk (S4, T4)
A one and half liter aliquot of milk is ashed to destroy organic material and then dissolved in concentrated mineral acid. Stable strontium is added to the eluted liquid or dissolved ash to facilitate chemical separation of Sr-89 and -90, and to determine the strontium recovery. Strontium concentrations and purification is ultimately realized by at least two precipitations of strontium nitrate in concentrated nitric acid. Additional iron / rare earth hydroxide precipitations and barium chromate separations are performed to remove suspected interfering nuclides. After purification, the Y-90 is allowed to ingrow for a known period of time. Sr-90 is then determined by counting yttrium oxalate after initially precipitating Y-90 hydroxide.
Sr-89 is determined by counting strontium carbonate and correcting the observed activity for the amount of Sr-90 and Y-90 on the planchet.
A sample of distilled water is used as a blank.

ENVIRONMENTAL DOSIMETRY (00), (D1) (ANALYZED BY RMC AND TELEDYNE IS0 TOPES)
By TI definition, a thermoltaninescent dosimeter (TLD) is considered one end of a capillary tube containing calcium sulfate (Tm) powder as the thennoltaninescent materi al. This material was chosen for its characteristic high light output, minimal thermally induced signal loss (f ading), and negligible self-dosing.
The energy response curve has been flattened by a complex multiple elenent energy compensator shield supplied by Panasonic Corporation, manufacturer 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 in Philadelphia from January 1 to July 1 and in Westwood, New Jersey from July 1 on.
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 envirornnental radiation exposure.
Data are normalized to standard machine conditions by correcting machine sett-ings 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.
A 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 (mren) by using a quality factor of 1.
Calculation of results and two sigma error:

DETERMINATION OF GROSS ALPHA AND/0R GROSS BETA ACTIVITY IN WATER SAMPLES (SUSPENDED AND DISS0LVED FRACTIONS)
TELEDYNE ISOTOPES This describes the process used to measure the overall radioactivity of water samples without identifying the radioactive species present. No chenical separation techniques are involved. One liter of the sample is filtered under vacuun through a 0.45 pm M1111 pore filter. The filter is dried and mounted on a 2 inch stainless steel planchet to represent the suspended fraction of the sample. The filtrate is evaporated on a hotplate, and the residue is transferred and dried on another planchet to represent the dissolved fraction of the sample.
The planchets are counted for 50 minutes in a low-background gas flow proportional counter. Calculation of activity includes a self-absorption correction for counter efficiency based on the weight of residue on each planchet.

DEIERMINATION OF TRITIUM BY GAS COUNTING (ANALYZED BY TELEDYNE ISOTOPES)
A 2 ml aliquot is changed into hydrogen gas and collected in an activated charcoal trap.
The hydrogen is then transferred into a previously evacuated one liter proportional counter. Non tritiated hydrogen and ultra-high purity methane is added and then counted.
Backgrounds and standards are counted in the same gas mixture as the samples.

DETERMINATION OF GAMMA EMITTING RADI0IS0 TOPES (TELEDYNE ISOTOPES)
Gamma enitting radioisotopes are determined by lithium-drif ted germanium (Ge(Li)) high resolution spectrometry in specific media, eg., 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 mf or 150 m2 bottles, or two-inch filter paper source geometries.
Sanples are counted on large ( >55 cc volume) Ge(Li) detectors connected to mult-channel pulse height analyzers and mini-computers for data acquisition and computations. All resultant spectra are stored on magnetic tape.
The analysis of each sanple consists of calculating the specific activities of all detected radionuclides or the detection limits from a standard list of 16 nuclides.
(L1) systems are calibrated for each standard geonetry using certifieu.adionuclide standards from Amersham /Searle and the National Bureau of Standards.
DETERMINATION OF RADIOSTRONTIUM IN MILK SAMPLES (TELEDYNE ISOTOPES)
Stable strontium carrier is added to 1 liter of sample and trichloracetic acid (TCA) is added to produce a curd.
The curd is separated by filtration and is discarded.
An oxalate precipitation is performed on the filtrate and the precipitate is ashed in a muffle furnace.
The ash is dissolved and strontium is precipitated as SrN03 using f tzning nitric acid. A barium chromate scavenge and an iron scavenge are then perfonned.
Stable yttrium carrier is added and the sample is allowed to stand for 7 to 10 days for yttrium ingrowth.
Yttrium is then precipitated as hydroxide, is dissolved and re-precipitated as oxalate. The yttrium oxalate is mounted on a nylon planchette and is cour.ied in a low level beta counter to infer Sr-90 activity.
Sr-89 activity is determined by precipitating SrC03 from the sample af ter yttrium separation. The precipitate is mounted on a nylon planchette and is covered with an 80 mg/cm2 altninum absorber for low level beta counting.

Results reported in pCi/ liter for milk and water, pCi/ sample for air particulates, and pCi/ kilograms for food products except K which is reported in mg/ liter for milk and mg/ kilogram for food products.
(a)
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 tne 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.
(b)
Two samples analyzed for Zn-65 were within the 2 sigma limits. One sample gave high results which may have been due to a low count time.
