STATE OF WISCONSIN 1985 POINT BEACH ENVIRONMENTAL RADIOACTIVITY SURVEY INTRODUCTION Thio report is prepared under U.S. Nuclear Regulatory Commission Contract NRC 30-83-647 by the State of Wisconsin, Department of Health and Social Services, Section of Radiation Protection. This report covers the calendar year 1985. Results of environmental radioactivity monitoring are listed in tabular form. The data presented consists of duplicative sample analysis such as air and TLD data and split sample analysis conducted by the otate radiation protection laboratory or subcontractor and the licensee. A brief description of sample collection techn!. ques and ana ytical procedures conducted by the state laboratory is also given. A cample collection summary for 1985 is included in Table 3. The sampl3 summary includes type and number of samples collected, Minimum Detectable Concentrations (MDC's) or Lower Limits of Detection (LLD's) as well as the range of reported activities for each type of sample a.'alysis.

SAMPLING TECHNIQUES Direct Radiation - Thermoluminescent Dosime'.ers (TLD's)

Continuous monitoring of direct radiation is performed quarterly using l thermoluminescent dosimeters. The dosimeters are placed at 43 locations in the area of the Kewaunee and the Point Beacil nuclear l power plants.

Air Samples Continuous air samples are collected weekly f rom two stations. Air particulate samples are collected on 47 mm. glass fiber filters. Air iodine samples are collected using charcoal absorbers mounted in tandem with the air particulate filters. The nominal sampling rate is 1 - 2.5 cubic feet of air per minute.

Surface Water A split sample consisting of 3.5 liters of liquid effluent is collected monthly at a point close to the discharge of the Point Leach effluent channel. This sample is a monthly composite of week 1v grab samples and is collected while the plant is discharging 11guld to the l channel. A background surface water sample is also taken at the Green Bay Pumping Station - Rostok,15.6 miles NNE. A surf ace water sample l from the Coast Guard Station, 4.8 miles SSE, is included as a i

background sample for Point Beach.

1

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

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

Sediment A split sample - for shoreline sediment is collected from three locations on an annual basis.

Fish Split samples of both migratory and non-migratory fish are collected periodically from locations in Lake Michigan near the Point Beach -

Kewaunee area.

Food Products A split sample for vegetation (grass) is collected from several locations in the Point Beach area.

ANALYTICAL PROCEDURES 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 Gamma 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(L1) detector and the gamma spectrum is collected. Scan the gamma spectrum for any peaks and print out regions of interest which would include possible plant attributable radionuclides. 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 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 the soluble and insoluble portions in an external gas flow proportional counter. Calculate activity correcting for counter efficiency and for self-absorption.

2

Surfect Water - Gemmo Ieotopic i A 3.5 liter sample is placed in a Marinelli beaker and analyzed on a GeLi detector. Scan the gamma spectrum for any peaks and print out regions of interest which would include possible plant attributable radionuclides. 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.

Veaetation g 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 f ood product sample is finely chopped. The sample is packed to the 500 mi 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 which would include possible plant attributable radionuclides. 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.

Soil of Sediment - Aloha, Beta and Gamma Isotopic Dry sample at 110 degrees Celsius, grind, and weigh into a stainless steel planchet. Beta and alpha count in an external gas flow proportional counter. Calculate activity correcting for self-absorption and counter efficiency.

The dried sediment is added to a 500 ml Marinelli beaker, weighed and counted on a Ge(L1) detector. Scan the gamma spectrum for any peaks and print out regions of interest which would include possible plant attributable radionuclides. 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 Isotocic 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.

3

Fish - Gamma Isotopic A sample is placed in a 500 ml. Marinelli beaker. Place the sample on a GeLi decentor and collect the gamma spectrum. Scan the gamma spectrum for any peaks and print out regions of interest which would include possible plant attributable radionuclides. 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, e

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 its 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 f or SLH is "AF". A complete listing of the EPA Cross Check results f or 1984 and 1985 is included in Table 4.

SENSITIVITIES AND ERROR - WISCONSIN 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 (.400) are based on the analysis performed and for gamma isotopic analysis have been calculated for a =ero decay time. Minimum detectable concentrations (MDC's) are listed in Table 3.

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.

4

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

4.66 sb E

  • V
  • 2.22
  • Y *S
  • exp(-dt)

, Where:

MDC is the "a priori" lower limit of detection as defined above, as picoeuries 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, E is the counting efficiency, as counts per disintegration, V is the sample size in units of mass or volume, 2.22 is the number of disintegrations per minute per picocurie, Y is the fractional radiochemical yield, when applicable, S is the self-absorption correction factor, d is the radioactive decay constant for the particular radionuclide, and t for environmental samples is the elapsed time between sample collection, or end of the sample collection period, and time of counting.

Guidelines adopted by the U.S. Environmental Protection Agency are used in the reporting of specific analyses. Results from specific analyses will be reported whether the results are negative, zero, or positive. Caution should be exercised in the interpretation of individual negative values. While a negative activity value does not have physical significance, it is significant when taken together with other obser ations which indicate that the true value of a distribution is near zero. This procedure will allow all of the data to be reported and will allow a statistical evaluation without an arbitrary cutof f of small or negative numbers. An estimation of bias in the nuclide analyses is then possible as well as a better evaluation of distributions and trends in the environmental data. It !

is important when reviewing the data in the following tables to compare the reported result to the actual minimum detectable concentration (MDC) for that analysis.

Results for specific analyses will be reported as an activity followed by an error term for that analysis. The error term is a plus or minus counting error term at the 2 sigma (95%) confidence interval and is printed as (+/-) .

SENSITIVITY - POINT BEACH The statement below is taken from a report submitted to the Point Beach nuclear f acility by Teledyne Isotopes Midwest Laboratory and applies to the reported data from January - June, 1985.

"For all gamma isotopic analyses, the spectrum is computer scanned from 80 to 2048 kev. Specifically included are Mn-54, Zn-65, Co-58, Co-60, Zr-Nb-95, Ru-103, Ru-106, I-131, Ba-La-140, Cs-134, Cs-137, Ce-141, and Ce-144. Na turally occurring gamma-emitters such as K-40 and Ra daughters are f requently detected but not listed here.

Data listed as "<" are at the 4.66 sigma level, others are 2 sigma.

Unless otherwise noted, the less than value ("<") is for Cs-137 and may be higher or lower for other radionuclides.

For reported data from July - December, 1985 the following statement would apply. According to Point Beach Radiological Effluent Specifications, analysis is only required on the radionuclides listed.

Radionuclides other than those reported were not detected. Naturally occurring radionuclides are commonly detected but are not reported.

Lower limits of detection (LLD's) are included in Table 3.

CONCLUSIONS A sample collection summary for 1985 is included in Table 3. The sample summary includes the type and number of samples collected as well as the range of reported activities for each type of sample analysis. Results from the individual sample analyses are listed in Tables 5-20.

Air Particulate Wisconsin and Point Beach maintain separate air sampling stations. The indicator site for both Wisconsin and f or 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 mil es NNE. The control site for Point Beach is located at Silver Lake College, 17 miles WSW.

A summary of reported activities by Wisconsin and Point Beach from air particulate samples is included in Table 3. Results from the individual sample analyses are listed in Tables 5-8. For Wisconsin, an air particulate sample was not collected at the indicator site for the period of 05/10/85 - 05/15/85 due to air pump problems.

The yearly averages, f rom a log-normal distribution, for the gross beta analysis on the air particulate filters are given in Table 1.

Results from the individual sample l

analyses are listed in Tables 9-10. The only radioisotope detected in the Wisconsin gamma isotopic analysis above its respective MDC was bery111um-7 (Be-7). Bery111um-7 (Be-7) is a naturally occurring radioisotope that is constantly produced through nuclear reactions between cosmic rays and nuclei in the atmosphere. Bery111um-7 (Be-7)

, was detected in composites from both the indicator and the control l sites. Point Beach does not report naturally occurring radioisotopes I and no comparison can be made for the bery111um-7 (Be-7) reported by Wisconsin.

At the observed lower levels o2 activity the Wisconsin and Point Beach data compared favorably in the gross beta and gamma isotopic analysis on the air particulate samples. Influence by the Point Beach nuclear f acility on air quality is not evident when comparing the data f rom the indicator and control sites.

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 sample is collected by Point Beach at the Coast Guard Station, 4.8 miles SSE.

A summary of reported activities by Wisconsin and Point Beach from the monthly surf ace water samples is included in Table 3. Results f rom the individual sample analyses are listed in Tables 11-14. For Wisconsin, the July, 1985 sample from the control site was not collected.

All reported activities by Wisconsin and Point Beach are at background levels for the samples taken at the indicator and control sites. All reported gamma isotopic activities by Wisconsin and Point Beach were less than the respective Wisconsin minimum detectable concentration (MDC) or the Point Beach lower limit of detection (LLD). The reported Wisconsin third quarter, 1986 activities for tritium (H-3) of 41300, 7701310 and 801300 pCi/ liter are comparable to the Point Beach third quarter, 1986 reported activity of <500 pCi/ liter. Wisconsin reported two activities for iodine-131 (I-131) of 1.710.3 and 0.610.2 pCi/ liter. All Point Beach reported activities for iodine-131 (I-131) were <0.5 pCi/ liter. Gross beta activities reported by Wisconsin and Point Beach were all at background levels for samples collected at the indicator and the control sites. The gross beta yearly average f or Wisconsin of 3.911.5 and 3.511.4 pCi/ liter and for Point Beach of

2. 8!O . 6 and 3.110.6 pCi/ liter for the Indicator and control sites respectively are not significantly different from reported yearly average gross beta awtivities from previous years.

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 Beach data for the indicator and control sites.

For Wisconsin, the detected levels of activity for cesium-137 (Cs-137)

, and for naturally occurring potassium-40 (K-40) were also reported in previous years. For Point Beach only cesium-137 (Cs-137) was detected above its respective lower limit of detection (LLD). Naturally occurring isotopes such as potassium-40 (K-40) are not reported by Point Beach.

At the low level of reported activities the Wisconsin and Point Beach data compare favorably.

Shoreline Sediments Split samples were taken for shoreline sediments at three locations.

A summary of reported activities by Wisconsin and Point Beach for shoreline sediment is included in Table 3. Results from the individual sample analyses are listed in Table 17.

From the Wisconsin gamma isotopic analysis, potassium-40 (K-40) was detected in all three samples and only trace activities for cobalt-60 (Co-60) and cesium-137 (Cs-137) from the discharge site B-12. The small detected activities f or cobalt-60 (Co-60) and cesium-137 (Cs-137) were below the respective NRC and Point Beach LLD's. Point Beach analysis did not detect or report any radioisotopes above their respective LLD and does not report naturally occurring radioisotopes such as potassium-40 (K-40).

Milk A split sample is taken f or milk. Milk is collected from the Funk farm, 3.8 miles WSW and f rom the Lehrmann f arm, 2.7 miles NNW.

A summary of reported activities by Wisconsin and Point Beach for milk samples is included in Table 3. Results f rom the individual sample analyses are listed in Tables 18-19. For Wisconsin, the March, 1985 milk sample from the Lehrmann farm was not collected due to an empty milk tank at the farm.

For Wisconsin, naturally occurring potassium-40 (K-40) was detected in all of the samples. All activities f or iodine-131 (I-131) were less than the Wisconsin MDC of 0.4 pCi/ liter. The detected activity f or cesium-134 (Cs-134) of 18 pC1/ liter is only slightly above the Wisconsin MDC of 12 pCi/ liter and was not reported by Point Beach.

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.

Influence by the Point Beach nuclear f acility is not evident af ter reviewing the data for Wisconsin and Point Beach.

Vecetation - Food Products .

Point Beach does not sample for food products. A split sample for vegetation was taken at four sites. -

A summary of reported activities by Wisconsin and Point Beach for vegetation samples is included in Table 3. Results from the individual sample analyses are listed in Table 20.

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 3000-6000 pCi/kg (wet). Point Beach does not report naturally occurring radioisotopes and no isotopes were reported above their lower limits of detection. Iodine-131 (I-131) was not detected in any of the Wisconsin or the Point Beach samples.

Influence by the Point Beach nuclear f acility is not evident af ter reviewing the data for Wisconsin and Point Beach.
