ENVIRONMENTAL RADIOACTIVITY SURVEY.
INTRODUCTION i
This 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 1984. Results of environmental radioactivity monitoring are listed in tabular form. The data presented consists of duplicative sample analysis i such as air and TLD data and split sample analysis conducted by the state radiation protection laboratory or subcontractor and the licensee. A brief description of sample collection techniques and analytical procedures conducted by the state laboratory is also given.
SAMPLING TECHNIQUES Direct Radiation - Thermoluminescent Dosimeters (TLD's)
Continuous monitoring of direct radiation is performed '
quarterly using thermoluminescent dosimeters. The dosimeters are placed at 29 locations in the area of the La Crosse Boiling Water Reactor (LACBWR) nuclear power plant.
Air Samples Continuous air samples are collected weekly from two stations.
Air particulate samples are collected on 47 -mm. glass fiber filters. Air iodine samples are collected using charcoal absorbers mounted downstream of the air particulate filters. The nominal sampling rate is one cubic foot of air per minute.
Surface Water A split sample is collected monthly at a point close to the discharge of the LACBWR effluent channel. This sample is a grab sample and is collected while the plant is discharging wastewater to the channel. A background surface water sample is also taken from Lock and Dam #8.

Milk A raw milk sample is collected monthly from one of three local farms located in the Genoa, Wisconsin area.
Sediment Sediment is collected from three locations in the Mississippi River channel on an annual basis.
Fish Game and scavenger fish are collected periodically from locations in the Mississippi River near the LACBWR nuclear power plant.
Food Products A blended sample of mixed vegetables was collected from a local garden.
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.

Direct Radiation Thermoluminescent dosimeters are supplied by the U.S. Nuclear 3
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 1 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 4 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 i 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 13
! following the conclusion section.
SENSITIVITIES AND ERROR - WISCONSIN DATA
, Following the recommendations of the Health Physics Society, i detection limits will be expressed as a minimum detectable a
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, i and type of sample. The MDC should not be viewed as an absolute l activity concentration that can or cannot be detected. Minimum l detectable concentrations (MDC) are based- on the analysis i

l
performed and for gamma isotopic analysis have been calculated for-a zero decay time.
The Wisconsin definition for minimum detectable concentration i follows closely the equation for the lower limits of detection as i i defined in the NRC contract NRC-30-83-647. Activities defined by a l the equation for MDC will be used in this report.
l' The MDC for each radioisotope has been calculated from the i following equation:
, +

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, l ab is the standard deviation of the background counting i rate or of the counting rate of a blank sample as ;
appropriate, as counts per minute, i E is the counting efficiency,- as counts per
- disintegration, 1
V is.the sample size in units of mass or volume, ;
i
, 2.22 is the number of disintegrations per minute per picocurie, i
j Y is the fractional radiochemical yield, when l applicable, S- is the self-absorption correction factor,-
k d is the radioactive . decay constant for 'the i particular radionuclide, and a
- t for- environmental samples is the. elapsed time i .between sample collection, or end of the sample
- . collection period, and' time of counting.
4 Guidelines adopted by the U.S. Environmental Protection Agency-
, are used in the reporting of specific analyses. Results irom j specific analyses will be reported whether the results are
! . negative,. zero,' or positive. -Caution should be exercised.in the interpretationLof individual negative values. While a ' negative i- activity :value does not have physical- significance, it- is significant when taken together with other.; observations 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 1
I 5-
O allow a statistical evaluation without an arbitrary cutoff 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 (+/-).
SENSITIVITIES - LACBWR DATA Lower limits of detection (LLD) or minimum detectable activity (MDA) as reported by LACBWR are defined in their manual LACBWR, HEALTH E SAFETY DEPARTMENT PROCEDURE, LACBWR ENVIRONMENTAL MONITORING PROGRAM. The method for calculating the LLD and a representative table of LLD's for LACBWR is included on pages 25 and 26 of this report. In most cases, reported activities for LACBWR are less than the required LLD's indicated on page 26.

. 4 CONCLUSIONS 4
Air' Particulate Wisconsin and LACBWR maintain separate air sampling stations.
The indicator site for both Wisconsin and LACBWR is located. at Lock & Dam #8, 0.7 miles N. The control site for Wisconsin is located at the state office building in La Crosse, 16 miles N and for LACBWR at the'Dairyland Power office in La Crosse.
l* The yearly averages, from a log-normal distribution for the gross
- beta analysis on the air particulate filters, are given in Table l 1.

l The LACBWR yearly averages for both the' indicator and control
! sites is approximately twice as high as the reported Wisconsin
! yearly averages .for respective sites. This difference is apparently due to the counting instrument used. With the purchase in early 1985 of a low background alpha / beta gas flow proportional' counting Canberra system, LACBWR has experienced an approximate-50% decrease in its gross beta activities.
- The Wisconsin and LACBWR yearly averages for gross beta on the i air particulate filters showed no significant differences between
, their respective indicator and control sites.

All of the reported radioisotopes for LACBWR were at trace activity levels and all were less than the respective Wisconsin MDC's.
At the observed lower levels of activity, the Wisconsin and LACBWR data compared favorably in the gross beta and gamma isotopic analysis on the air particulate samples. Influence by the LACBWR nuclear facility on air quality is not evident when comparing the data from the indicator and control sites.
Air Iodine All reported air iodine measurements of the cartridges, for both Wisconsin 4
and LACBWR, were all below the required NRC LLD of 0.07 pCi/M 3 for the sites at Lock and Dam #8 and at La Crosse.
Surface Water The surface water samples are split samples taken as a grab sample on a monthly basis. 'The discharge channel is taken as the indicator site and Lock and Dam #8 is taken as the control site.
The Wisconsin and LACBWR gamma isotopic analysis of the surface water samples detected the-following radioisotopes above the respective minimum detectable concentration for the indicated '
months. ,

l Differences in gross beta reported activities were noted in j January, February and March for the discharge channel site. Gross I beta activities are compared by adding the two individual gross l beta activities from. the soluble and insoluble portions for
] Wisconsin and comparing that sum'with the LACBWR reported gross j beta activity. For Wisconsin the higher gross beta activity was in the insoluble portion. After correspondence in April'1984, it j was suggested that the lower reported results by LACBWD for gross j beta activities could be due to improper mixing in the' sample j preparation of the surface water sample or to problems' associated with the calibration .of the gas flow' proportional counter.
Thorough . mixing was initiated in~ April.1984 and. agreement in the Wisconsin and LACBWR reported results for gross beta activities j has been substantially better.
Tritium (H-3) continues to be a problem for LACBWR. It is noted
, for LACBWR that tritium problems exist for both the indicator
! and the control sites. Tritium results between Wisconsin and i LACBWR can not be compared until the analysis problems are j, resolved. It was suggested by the LACBWR Radiation Protection Engineer that a cross check program for tritium should be set up between LACBWR and Wisconsin. It is hoped that this cross check program will be initiated in 1985. '
! After reviewing the gamma isotopic results'for both Wisconsin and * '
j LACBWR, the gamma isotopic differences noted in Table 4 could not j
be resolved due to possible difficulties associated with the ..
gamma isotopic procedure. The gamma isotopic differences noted I
during . January, February and March could be~related to improper mixing during. sample preparation as mentioned previously. ;
Thorough mixing was initiated in April 1984 and agreement'in the Wisconsin and LACBWR reported results for gamma isotopic 10
activities has been substantially better. The Co-60 detected by Wisconsin in the 06/13/84 sample from the discharge channel could be a Wisconsin problem. The Wisconsin reported gamma isotopic activity for Co-60 does not agree with the reported Wisconsin gross beta activity for the 06/13/84 sample. It is noted that LACBWR reported similiar Co-60 activities for the control and the
, indicator samples collected on 09/12/84. Higher backgrounds experienced in the LACBWR environmental laboratory could explain the similiar reported Co-60 activities for the control and
, indicator samples collected on 09/12/84. The other gamma isotopic differences for 11/14/84 and 11/15/84 are small and could be explained due to the low activity of the samples.
All activities reported by either Wisconsin or LACBWR are below the standards for uncontrolled areas as specified in ICRP Report No.2 or 10 CFR 20.
Fish Both LACBWR and Wisconsin analyze the same samples with LACBWR first performing its analysis and then Wisconsin.
The Wisconsin and LACBWR gamma isotopic analysis of the fish samples detected the following radioisotopes above their respective MDC or MDA.

i attributable to the LACBWR facility operation.
! Inspection of the Wisconsin data from the discharge point shows a i range of activity for'Co-60 and Cs-137 for the three collection i dates.. The range of reported activity for Co-60 was 7100 - 32400 1

i reported activities for the 10/17/84 samples. This observation i would tend to indicate that the discharge point is not the best i site to observe trends of accumulated radioactivity versus time.
From correspondence with Dairyland- -Power Cooperative environmental department personnelf their observations are that the discharge point has a very small area to collect bottom sediment with larger aggregate predominating. This observation ,
together with the. fact that there is also a high scouring rate at j the discharge point would support the argument that the discharge
- point is not a good site to study trends of accumulated .
, radioactivity versus time.
I The Wisconsin reported activities from duplicate samples
! collected on 03/27/84 and 06/26/84 at the discharge point illustrate the problems of obtaining representative samples. The Wisconsin reported activities for Co-60 and Cs-137 are
- significantly different for the duplicate samples.
Representative samples from highly attentuating substances such 4 as soil or bottom sediments are difficult to obtain. *
} Dose calculations from exposure to bottom sediments will be discussed later in the. conclusion section, j Milk
. The milk-samples are obtained as grab samples on a monthly basis
- and are then split for analysis.

Wisconsin detected only naturally occurring potassium-40 above its MDC in its gamma isotopic analysis of the milk samples.
Activities for iodine-131 were all below its MDC of 0.40 pCi/1.
LACBWR does not report naturally occurring radioisotopes and a comparison is not possible with-the Wisconsin data. All of the reported isotopes were less than the respective Wisconsin MDC's except for those differences listed in Table 10.
Table 10. Differences in reported results between Wisconsin and LACBWR for milk samples.

The 2.9+/-0.9 pCi/l reported by LACBWR is less than its MDA of 5 pCi/1. For the 11/13/84 sample, an inspection of the Wisconsin and LACBWR analysis does not provide an explanation for the difference in the reported result for Co-
- 60. It should be noted that Co-60 would not commonly be present in milk 'and the reported activity by LACBWR for the 11/13/84 sample is questionable.
The data reported by Wisconsin for 1984 is comparable to data reported for previous years. Influence by the LACBWR facility is not apparent in the milk samples analyzed by either Wisconsin or LACBWR.
Vegetation - Food Products A split sample of food products was taken in 1984. A blended sample of mixed vegetables was collected from a local farm, 1.0 mile NE.
The Wisconsin and LACBWR gamma isotopic analysis of the blended food product sample detected the following radioisotopes above their respective MDC or MDA listed in Table 11.

- Dose to Man from Liquid Effluent Pathways
) Dose _ calculations from liquid effluent releases were performed
- according to the mathematical models illustrated in USNRC Regulatory Guide 1.109. Doses from liquid effluents according to Regulatory Guide 1.109 result from the following pathways
potable water, aquatic foods, dose from shoreline deposits and 4 dose from foods grown on land with contaminated water. For l LACBWR the pathways for potable water and dose from foods' grown
- on land with contaminated water do not normally apply, as I
4 required by LACBWR's new technical specifications.
i Total body doses were calculated for the maximum exposed j individual. A minimum ~ detectable total body dose was calculated
! using the Wisconsin respective MDC for isotopes that might be I found in liquid effluents. For liquid affluents the Wisconsin 1 minimum detectable total body dose was calculated to be 0.024-mrem / year from exposure to bottom sediments and 0.29 mrem / year l from ingestion of~ fish.

The c. ,harge point, however, is not readily accessible for individual use for recreational purposes including either fishing or swimming. According to the new Tech Specs for LACBWR, based upon USNRC Regulatory Guide 1.109 for liquid effluents, the worst possible pathway is from ingestion of fish. As computed from Wiscansin MDC's, the maximum total body dose of 0.29 mrem / year from ingestion of fish is well within the maximum permissible dose of 3 mrem / year, as stated in 10 CFR 50, and in accordance with LACBWR's new technical specifications.
Bottom sediments and fish will continue to be monitored inorder to observe trends of accumulated radioactivity versus time.
