STA~E OF iiISCCNSIN 1984 POINT BEACE ENVIRO!DCEN"AL RADICAC~IVITY SURVEY INTRODUCTION This report is prepared under U.S. Nuclear Regulatory Cc==issica Contract NRC 30-83-647 by the State of Wisconsi=, Depart =ent of Health and Social Services, Section of Radiation Protection. This report covers the calendar year 1954. Results of environ ental radicactitity

=cnitoring are listed in tabular for=. The data presented censists of duplicative sa=ple analysis such as ai and ~~LD data and split sa=ple analysis conducted by the state radiatica protecticn laboratory or subcentracter and the licensee. A brief descriptien of sa=ple i collection techniques and analytical procedures conduc*ed by the state laboratory is also given.

SAMPLING TECENICUES Direct Radiation - Ther=oluainescent Desi eters (TLD's)

Centinucus =cnitoring of direct radiation is perfor=ed quarterly using ther=clu=inescent desi=eters. The desi=eters are placed at 43 locations in the area of the Eevaunee a=d the Pai-- =each nuclear pcver plants.

Air Sa=cles Continuous air sa=ples are collected weekly frc= two stations. Air particulate sa=ples are collected on 47 =n. glass fiber filters. Air iodine sa=ples are collected using charcoal abscrhers =cunted in tande= with the air particulate filters. The nc=inal sa=pling rate is one cubic foot of air, pe- -'-"*e.

Surface Water

~

A split sa=ple consisting of 3.5 liters of liquid effluent is collected =enthly at a point close to the discharge of tne Point Beach effluent channel. This sa ple is a =cathly ec=pesite of weekly grab sa=ples and is collected while the plant is discharging liquid to the channel. A background surface water sa:ple is also taken at the Green Bay Pu= ping Station - Rostok. A surface water sa ple frc= the Coast Guard Station is included as a hackground sample for Point Seach.

4 Milk A raw milk sample is collected monthly from the Lehrmann farm and W.

Funk farm. The milk sample is a split sample for both Wisconsin and the Point Beach nuclear power facility.

Sediment Sediment is collected from three locations on an annual basis.

Fish -

Both migratory and non-migratory fish are collected periodically from ,

j locations in Lake Michigan near the Point Beach - Kewaunee area.

Food Products Vegetation in the form of grass is collected from several locations in the Point Beach area.

) ANALYTICAL PROCEDURES 4

The procedures given are abstracted to present only the basic steps.

The analysis of the samples has been subcontracted to the State Laboratory of Hygiene. A detailed description of the procedures used is available from the State Laboratory of Hygiene.

Air Particulate Samples - Beta Gammu Place the 47 mm. glass fiber filter on a 2-inch stainless steel planchet. Beta count in an external gas flow proportional counter.

Calculate activity correcting for counter efficiency. .

Air Particulate Samples - Gamma The monthly composite of air particulate filters is placed on a Ge(Li)

, detector. Determine the gamma spectrum using 2048 channels of the

! Canberra Model 85 multichannel analyzer. Scan the gamma spectrum for any peaks and print out regions of interest. Calculate the activity for isotopes in the regions of interest, regardless if they are above or below the minimum detectable concentration, correcting for counter efficiency and for decay.

~

Surface Water - Alpha, Beta Gamma l

Filter a 500 ml. aliquot of sample. Evaporate filtrate in a 2-inch .

. stainless steel planchet. Place filter paper in a 2-inch stainless

! steel planchet and dry at 103 degrees Celsius. Beta and alpha count l the soluble and insoluble portions in an external gas flow l proportional counter. Calculate activity correcting for counter i efficiency.

I l

Surface Water - Gamma Isotopic

( A 3.5 liter sample is placed in a Marinelli beaker and analyzed on a l

l l 2 I

GeLi detector. The sample is counted for 100 minutes using 2048 channels at 1.0 Kev per channel. Scan the gamma spectrum for any ,

peaks and print out regions of interest. Calculate the activity for l isotopes in the regions of interest, regardless if they are above or below the minimum detectable concentration, correcting for counter efficiency and for decay, i Vegetation or Food Product - Alpha, Beta and Gamma Isotopic Dry sample at 110 degrees Celsius, grind, weigh into stainless steel planchet. Beta and alpha count in an external gas flow proportional counter. Calculate activity correcting for self-absorption and counter efficiency.

The food product sample is finely chopped. The sample is packed to the 500 ml mark of a 500 ml Marinelli beaker, weighed and counted for 900 minutes on a Ge(Li) detector. Scan the gamma spectrum for any peaks and print out regions of interest. Calculate the activity for isotopes in the regions of interest, regardless if they are above or below the minimum detectable concentration, correcting for counter efficiency and for decay.

Milk - Gamma Isotopic Procedure same as for Surface Water.

Milk - Iodine 131 Chemical Extraction A stable iodine carrier is added to a 2 liter sample of raw milk. The sample is passed through an anion exchange column and the iodine is removed from the resin by batch / extraction using NaOC1. After reduction to elemental iodine by hydroxylamine hydrochloride, the iodine is extracted into carbon tetrachlorine reduced with bisulfite, and back extracted into water. The iodine is precipitated as palladous iodide with the chemical yield determined gravimetrically and counted in an external gas flow proportional counter correcting for counter efficiency and for decay.

Fish - Gamma Isotopic A sample is placed in a 500 ml. Marinelli beaker. Place the sample on a GeLi detector and count for 100 minutes. Determine the gamma spectrum using 2048 channels set at 1.0 Kev per channel. Scan the gamma spectrum for any peaks and print out regions of interest.

Calculate the activity for isotopes in the regions of interest, regardless if they are above or below the minimum detectable concentration, correcting for counter efficiency and for decay.

Direct Radiation Thermoluminescent dosimeters are supplied by the U.S. Nuclear Regulatory Commission. The exposed TLD's are shipped to NRC Region I and are read by the Commission.

QUALITY ASSURANCE The analysis of the samples is performed under subcontract with the State Laboratory of Hygiene (SLH). SLH maintains their own quality assurance program which was also reviewed by the NRC in January, 1985.

Analytical procedures provide for routine replicate analyses to verify methods and instrument operation. Traceable sources are used to regularly calibrate the counters and daily performance checks are made between calibrations. In addition, quality control charts are maintained on the counters. ,

SLH participates in the EPA Cross Check program. The quality assurance progam that the SLH participates in include analysis of -

blind samples, air filters, food, milk, gamma in water, alpha-beta in water, iodine in water, strontium in water and tritium in water. The EPA Cross Check code for SLH is "AF". A complete listing of the EPA Cross Check results is included in Table 7 following the conclusion section.

SENSITIVITIES AND ERROR - WISCONSIN DATA Following the recommendations of the Health Physics Society, detection limits will be expressed as a minimum detectable concentration (MDC).

The minimum detectable concentration or MDC is an "a priori" estimate of the capabliity for detecting an activity concentration by a given measurement system, procedure, and type of sample. The MDC should not be viewed as an absolute activity concentration that can or cannot be detected. Minimum detectable concentrations (MDC) are based on the analysis performed and for gamma isotopic analysis have been calculated for a zero decay time. "

The Wisconsin definition for minimum detectable concentration follows closely the equation for the lower limits of detection as defined in the NRC contract NRC-30-83-647. Activities defined by the equation for MDC will be used in this report.

The MDC for each radioisotope has been calculated from the following equation:

4.66 sb MDC = -

E * *

• V 2.22 Y *S

• exp(-dt)

Where: -

MDC is the "a priori" lower limit of detection as defined above, as picocuries per unit mass or volume, sb is the standard deviation of the background counting rate or of the counting rate of a blank sample as appropriate, as counts per minute, 4

CONCLUSIONS Air Particulate i

Wisconsin and Point Beach maintain separate air sampling stations. The indicator site for both Wisconsin a'nd for Point Beach is located at

the residency at the north property line, 1.3 miles NNW. The control ~

! site for Wisconsin is located at the Green Bay Pumping Station -

} Rostok, 15.6 miles NNE. The control site for Point Beach is located

, at Silver Lake College, 17 miles WSW. .

The quarterly and yearly averages for the gross beta analysis on the air particulate filters are given in Table 1. For Wisconsin the averages are from a log-normal distribution.

Indicator site Be-7 12 0.052 - 0.12 Control site Be-7 1 0.10 Point Beach (quarterly composite)

No radioistopes were reported.

All of the detected radioisotopes were near the respective MDC for Wisconsin. The Point Beach quarterly analysis ~on the air particulate filter composites detected no isotopes above the less than value as stated for cesium-137. Beryllium-7 is not commonly analyzed for as stated in the section: Sensitivity - Point Beach Data.

At the observed lower levels of activity the Wisconsin and Point Beach data compared favorably in tie gross beta and gamma isotopic analysis on the air particulate samples. Influence by the Point Beach nuclear facility on air quality is not evident when comparing the data from the indicator and control sites.

i Air Iodine Air iodine measurements for both Wisconsin and Point Beach were all below the required NRC LLD of 0.07 pCi/M*3 for the indicator and control sites.

Surface Water

. Surface water from the effluent channel is a split sample. This sample is a monthly composite of weekly grab samples. Surface water from a control site is not a split sample. Wisconsin collects a monthly grab sample at the Green Bay Pumping Station - Rostok, 15.6 miles NNE. A monthly grab samplo is collected by Point Beach at the Coast Guard Station, 4.8 miles SSE.

The Wisconsin and Point Beach analysis of surface water samples detected the radioisotopes listed in Table 3. All gamma isotopic analyses by Wisconsin and Point Beach were below the respective MDC's or LLD's for both the indicator site and the control site.

Control site - Coast Guard Station H-3 1 (quarterly) 1030 The detected activities for tritium (H-3) from the indicator site, as reported by Wisconsin and Point Beach, are comparable when a quarterly average is taken for the reported Wisconsin results. The detected Wisconsin activities for iodine-131 (I-131) from the indicator site can not be compared since the Wisconsin reported activities of 0.55 and 1.8 pCi/ liter are less than the respective Point Beach LLD of 10 pCi/ liter (as calculated for Cs-137).

Comparison of the control site (background sample) is not possible as Wisconsin and Point Beach sample at different locations. It is noted that the reported Point Beach 1st quarter activities for tritium (H-3) from the indicator site and control site are <500 pCi/ liter and 1030 pCi/ liter, respectively. From the reported Point Beach activities it would appear that the reported activity at the control site is not attributable to the Point Beach facility.

The Wisconsin gross beta yearly average was 4.5+/-1.8 pCi/l at the indicator site and 3.7+/-l.8 pCi/l at the control site. The Point Beach gross beta yearly average was 3.1+/-0.6 pCi/l at the indicator site and 3.9+/-0.6 pCi/l at the control site. The Wisconsin and Point Beach yearly gross beta averages for the indicator and control sites are not significantly different from the reported 1983 yearly gross beta averages for respective sites. All activities reported by either Wisconsin or Point Beach are below the standards for uncontrolled areas specified in ICRP Report No. 2 or 10 CFR 20. Plant influence is not evident after comparing Wisconsin and Point Peach data for the indicator and control sites.

Fish Split samples were taken for fish. The samples were obtained from the Point Beach pumphouse.

The Wisconsin and Point Beach analysis of the fish samples detected the radioisotopes listed in Table 4.

For Wisconsin the detected levels of activity for cesium-137 (Cs-137) and naturally occurring potassium-40 (K-40) were also reported in the Point Beach Environmental Radioactivity Survey for 1983. For Point Beach no isotopes were detected above their respective lower limits of detection. Point Beach reported their results as T500 pCi/kg based on cesium-137 detection limits. Naturally occurring isotopes such as potassium-40 are not reported by Point Beach.

Comparison with the Wisconsin data is not possible at the lower limits of detection reported by Point Beach and the fact that Point Beach does not report naturally occuring radioisotopes.

! comparison can be made with the Wisconsin data. Trace activities for i

cesium-137 are commonly detected in soil and shoreline sediment samples collected by Wisconsin in other areas of the state.

Milk .

A split sample is taken for milk. Milk is collected from the Funk

• farm, 3.8 miles WSW and from the Lehrmann farm, 2.7 miles NNW.

The Wisconsin and Point Beach analysis of milk samples detected the radioisotopes listed in Table 6.

For Wisconsin, naturally occurring potassium-40 (K-40) was detected in all of the samples. The detected activities for iodine-131 (I-131) are only slightly above the Wisconsin MDC of 0.4 pCi/ liter. Point Beach did not detect any isotopes above their lower limits of detection in its gamma isotopic analysis. All reported results for iodine-131 were less than 0.5 pCi/1. Naturally occurring potassium-40 (K-40) is not reported by Point Beach.

Comparison with the Wisconsin data is not possible at the lower limits of detection reported by Point Beach and the fact that Point Beach does not report naturally occurring radioisotopes. Influence by the Point Beach nuclear facility is not evident after reviewing the data -

for Wisconsin and Point Beach.

l Vegetation - Food Products '

Point Beach does not sample for food products. A split sample was

. taken for vegetation at three sites.

Only naturally occurring potassium-40 (K-40) above its MDC was detected in the gamma isotopic analysis of the Wisconsin samples.

Potassium-40 was detected in all three samples in the range of 1900-7100 pCi/kg (wet). Point Beach does not report naturally occurring radioisotopes and no isotopes were reported above their lower limits of detection. Iodine-131 was not detected in any of the Wisconsin or the Point Beach samples.

Comparison with the Wisconsin data is not possible at the lower limits '

of detection reported by Point Beach and the fact that Point Beach does not report naturally occurring radioisotopes. Influence by the Point Beach nuclear facility is not evident after reviewing the data for Wisconsin and Point Beach.
