INTRODUCTION This report covering the calendar year 1991 is prepared under U.S. Nuclear Regulatory Commission Contract NRC 30-83-647 by the State of Wisconsin, Department of IIcalt and -

Social Services, Radiation Protection Unit (WI D11SS). Results of environmental radioactivity monitoring are listed in tabular form. The data presented consists of duplicative sample analysis conducted by the state radiation protection laboratory or subcontractor and the licensee. A sample collectlan summary for 1991 is included in Tab!c 10. The sample summary includes type -

and number of analyses performed, Minimum Detectable Concentrations (MDC's) or Lower _.

3 l

Limits of Detection (LLD's) as well 1s the range of reported activities for each type of simple

~

analysis.

SAMPLING TECHNIQUES l

Whenever possible a split sample is taken in order to obtain a valid comparison between WI DilSS and Point Beach results. Split sampling involves the thorough mixing of a sample into a homogeneous mixture that is then split between WI DHSS and Point Beach.

DiIcel Rad.i.ati m - Thermoluminesteni Dosirnsten (fl.D's) 2 l

Continuous monitoring of direct radiatica is performed quarterly using thermoluminescent dosimeters.

The dosimeters are placed at 43 locations in the area of the Kewaunae and the Point Beach nuclear power plants.

Air Smurki l

Continuous air samples are collected weekly from sites 2 and 9. 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 2.5 cubic feet of air per minute i

depending on the type of pump used.

Su1Lx c E ater A split sample of liquid effluent is collected monthly at site 1 (Point Peach discharge channel. This f.

sample is a monthly composite of weekly grab samples and is collected while the plant is discharging liquid to the channel. A background surface water sample is taken for WI DIISS r.t site 9 (Green Bay Pumping Station - Rostok,15.6 rai!es NNE). A surface water sample from site 6 (Coast Guard Station,4.8 miles SSE) is included as a background sample for Point Beach. The background surface samples are not split samples.

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

QUALITY ASSURAt4CE i

The analysis of the samples is performed under subcontract with the State Laboratory of Hygiene (SLH). SLH maintains its own quality assurance program. Analytical procedures provide for i

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 program that the SLH participates in include analysis of performance samples, air Elters, 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 for 1991 is i

included in Table 11.

SENSITIVITY AND ERROR - WISCONSIN DHSS l

Following the recommendations of the Health Physics Seiy, detection limits will be expressed as a minimum detectable concentration (h1DC). The minimum detectable concentration or hfDC is an "a priori" estimate of the capability for detecting an activity concentration by a given measurement system, procedure, and type of sample. The hiDC should not be viewed as an absolute activity concentration that can or cannot be detected, hiinimum detectable concentrations (MDC) are based on the analysis performed and for gamma isotopic anaipis have been calculated for a zero decay time. hiinimum detectable concentrations (hiDC's) are listed in Table 10.

.-_.._,-y-,

s 1

The WI DilSS 6efinition for minimum detectable concentration follows closel_y the equation for the lower limits of detection as denned in NRC contract NRC-30-83-647. Activities denned by the equation for MDC will 5 used in this report.

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

4.66 s, MDC = --

E

V

2.22

Y

S

exp(-dt)

MDC is the 'a r.riori" lower limit of detection as defined above, as picoeuries per unit mass or volume, s,.

is the standard deviz. tion of the background counting rate or of the counting rate of a blank sample as appropriate, as sounts per minute, E

is the counting efficiency, as counts per disintegration, l

l V

is the sample size in units of mass or valume.

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 ccnstant for the particular radionuclide, and t

for environmental samples is the elapsed time between sample collection, or end of the sample collection period, and ume of counting.

Results for specific unalyses will be reported as either a MDC value or 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 primed as (+/-).

ht?SITIVITY - POINT 8EACH Except for naturally occurring radionuclides, all radionuclides detected at concentrations equal to or above their LLD are reported. Only the radi)nuclides specifically identified in the PBNP Radiological Efnuent Technical Specifications are reported as less than the LLD.

WI DilSS and Point Beach maintain separate air sampling stations. The indicator site for both WI DilSS and for Point Beach is located at site 2 (north property line,1.3 miles NNW). The control site for Y!! DilSS is located at site 9 (Green Bay Pumping Station - Rostok,15.6 miles u

NNE). The control site for Point Beach is located at site 10 (Silver Lake College,17 miles s

WSW).

A summary of reported gross beta activities by WI DHSS and Point Beach from air particulate

' i samples is included in Table 10. Results from the individual sample analyses are listed in Tables 12-15.

The quarterly or yearly averages for the gross beta activity on the air particulate filters are listed in Table 6. A comparison of WI DilSS and Point Beach data in Tables 12-15 was done using a procedure described in the NBC JNSPECTION MAliUAL INSPECTION PROCEDURE 84750.

In Tables 12-15, data that is underlined in the ratio column indicates that the WI DIISS and Point Beach data are not in agreement. Gross beta analysis is dependent on the radionuclide used for i

calibration and the documented standard procedure that is followed. The WI DilSS's documented procedure for gross beta analysis on air particulate samples was inspected and no explanation can be given for the differences noted in Tables 1215. There were no significant differences between the respective WI DilSS and Point Beach indicator and control sites.

From WI DilSS gamma isotopic analysis, beryllium-7 (?Be) was detected in all composites from both the indicator and the control sites. Beryllium-7 (7Be) is a naturally occurring radioisotope that is constantly produced through n iclear reactions between cosmic rays and nuclei in the atmosphere. All other radionuclides were below their respective WI DilSS's MDC.

Point Beach did not report any activities above their respective LLD. Point Beach is not required to report naturally occurring radioisotopes and no comparison can be made for the beryllium-7

('Be) reported by WI DilSS.

At the observed low level of activity the WI DilSS and Point Beach data are comparable in the gamma isotopic analysis of the air particulate samples. Influence by the Point Beach nuclear facility on air quality is net evident when comparing the data from the indicator and control sites.

Tables 18-20 are the quarterly listings for the U.S. Nuclear Regulatory Commission's (US NRC) and Point Beach TLD programs for the Point Beach arer, Table 7 is a comparison of quarterly and yearly exposure data at collocated sites. Table 8 is a comparison of exposure data at different distances from the Poim Beach facility. All exposures for the US NRC are normalized to a 90-day quarter (standard quarter) and are reported in units of milliroentgens (mR). All exposures for Point Beach are normalized to a 7-day period and are reported in units of milliroentgens (mR). For the purposes of comparison in this report, the Point Beach exposure data (normalized to a 7-day period) is converted to the US NRC standard quarter (90-day) using

.the conversion factor 90/7.

I A comparison of WI DlISS and Point _ Beach TLD data in Tables 7-8 was done using a procedure l

described in the NR.C INSPECTION MANUAL INSPECTION PROCEDURE 8475(). Without 2

access to_either the USNRC or Point Beach quality control programs, no explanation can be give given for the indicated diiTerences in Tables 7-8.

During the first b.rter, a nunber of envirornental TLDs were discovered to be wet or oNque upon aa return to the ver for readout. The higher than normal results repoets for these son orits stations are suspected to be due interference 'n TLD readout caused by the moisture camage incurred by the ILD chips.

At distances of 0-2 miles,2-5 miles and > 5 miles from the Point Beach facility, the US NRC composite TLD data are not significantly different. Likewise, at these same distances the Point Beach data are not s;gnificantly different. With no significant differences, influence by the Point Beach facility on air quality is not evident.

Sitdage Waty_r The indicator site for WI DilSS and Point Beach is located at site 1 (effluent channel) and is a split sample. This sample is a monthly composite of weekly grab samples. The control site is rat a split sample. WI DilSS collects a monthly grab sample at site 9 (Green Bay Pumping Station - RosioL,15.6 miles NNE). A monthly grab sample is collected by Point Beach at site 6 (Coast Guard Station,4.8 miles SSE).

A surnmary of reported activities by WI DilSS and Point Beach from the monthly surface water samples is included in Table 10. Results from the individual sample analyses are listed in Tables 21-24.

All reported activities by WI DHSS and Point Beach are at background levels for the samples taken at the control sites (6 and 9). All reported gamma isotopic activities were less than the respectise WI DilSS MDC or the resnective Point Beach LLD. Gross beta and tritium ('ll)

I activities reported by WI DilSS and Point Beach are at background levels. The gross beta yearly average for WI DHSS of 3.4 f_ l.6 pCilliter and for Point Beach of 2.5 d. 0.7 pCi/ liter for the e

control sites are not significantly different from previous years.

For samples taken at the indicator site (1), alt reported gamma isotopic activities were less than t

the respectiva WI DilSS MDC or the respective Point Beach LLD. The gross beta yearly aveiage for WI DHSS of 2.9 i 1.4 pCilliter and for Point Beach of 2.4 A 0.5 pCi/ liter is not significantly different from previous years.

All activities reported by either WI DHSS 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 WI DHSS and Point Beach data for the indicator and control sites.

t C

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

A summary of reported activities by WI DHSS and Point Beach for fish samples is included in Table 10. Results from the individual sample analyses are listed in Table 25.

The WI DHSS detected activities for cesium-137 ("'Cs) and for naturally occurring potassium-40

(*K) wcre also reported in previous years. For Point Beach, cesium-137 ("7Cs) was detected in all samples and all other rep,0Ni gamma isotopic activities were less than their respective LLD.

Naturally occurring radioisotopes such as potassium-40 (*K) are not required to be repocteu by 13

Point Ba:@ At the low level of reported activities the WI DIISS and Point Beach data are O

cemvaret>i.

Shoreline Sediments Split samples were taken for shoreline sediments at sites 1,'3 and 6.

l A summary of reported activities by WI DHSS and Point Beach for shoreline sediment is-included in Table 10. Results from the individual sample analyses are listed in Table 26.

From the WI DHSS gamma isotopic analysis, cesium-137 ("'Cs) and naturally occurring potassium-40 ("K) and radioisotopes from tiranium and thorium decay series were detected in all three samples.

Point Beach analysis detected cesium-137 ("7Cs)in all three samples and is not required to report naturally occurring radioisotope.

At the low level of reported activities the WI DHSS and Point Beach data are comparable.

Milk Split samples were taken for milk. Milk is collectcd from site 7 (Funk farm,3,8 miler. WSW) and from site 8 (Enbelbrecht farm,2.2 miles NW).

A summary of reported activities by WI DHSS and Point Beach for milk samples is included in Table 10. Results from the individual sample analyses are listed in Tables 27-28.

For WI DHSS only naturally occurring potassium 40 (*K) was detected in all of the samples.

Excepi for one activity of 0.5 i 0.1, all activities for iodine-131 (" I) were all less than the WI DHSS MDC of 0.5 pCi/ liter.

4 Poin' Beach did not detect any radioisotopes above their lower limits of detection in its gamma' isotopic analysis. Reported ree 5 Sr iodine-131 (" I) were all less than 0.5 pCi/ liter.

Naturally occurring radioisotopec smo as potassium-40 (*K) are not required to be reported by Point Beach.

. Influence by the Point Beach nuclear facility in the milk pathway is not evident after reviewing the WI DHSS and Point Beach data.

E A summary of reported activities by WI DHSS and Point Beach for vegetation sr.mples is O

included in Table 10. Results from the individual sample analyses are listed in Table 29.

From the WI DHSS pmma isotopic analysis, naturally occurring potassium-40 (*K) and beryllium-7 (7Be) were detected. Activities for iodine 131 ("'l) were below the WI DllSS MDC of 60 pCi/kg.

Point Beach is not required to report naturally occurring radioisotopes and no comparison is possible for the reported WI DHSS activities for beryllium-7 ('Be) and potassium-40 ("K). Point Beach did not de'ect any radioisotopes above their respective LLD. Activities for iodine-131

("'l) were below the Point Beach LLD of 60 pCi/kg.

Influence by the Point Beach nuclear facility in the food pathway is not evident aner reviewing the data for WI DHSS and Point Beach.

P_ps to an Averaic hallvidual Dose calculations for gaseous and liquid efnuent releases were performed according to the mathematical models illustrated in USNRC Regulatory Guide 1.109, " Calculation of Annual Doses to Man from Routine Releases of Reactor Effluents for the Purpose of Evaluating Compliance with 10 CFR Part 50, Appendix 1".

The doses, listed in Table 9, were calculated for the average exposed individual for WI DHSS sampas with activit.ics greater than MDC.

The dose to an average individual from the ingestion of fish are most likay due to background levels of radiation attributable to fallout from previous atmospheric nuclear tests and not to the operation of the Point Beach facility. The dose to an average individual from the ingestion of fish are due specifically to the detected cesium-137 ("'Cs) activities.

The U.S. Environmental Protection Agency (EPA) in document 40 CFR Part 190 rectricts tiu f

annual exposure of the population from all parts of the nuclear fuel cycle, including nuclear power plants. Doses resulting from gaseous and hquid effluent releases from the Point Beach nuclear facility meet the 25 mR/ year criteria of 4C 9FR Part 190,
