State of Wisconsin 1980 Point Beach Environmental Radioactivity Survey Ih7RODUCTION This report is prepared under U. S. Nuclear Regulatory Commission Contract NRC-05-80-275 by the State of Wisconsin, Department of Health an.1 Social Services, Section of Radiation Protection. This report covers the calendar year 1980. Results of environmental radioactivity monitoring are list.ed in tabular form. The data presented consists of duplicative sample analysis such as air and TLD data and split sample analy. sis 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 are also given.

SA'GLING TECHNIQUES Direct Radiation - Thermoluminescent Dosimeters (TLD's)

Continuous monitoring of direct radiation is performed quarterly using thermoluminescent dosimeters. The dosimeters are placed at five locations in the area of the Point Beach nuclear power facility.

Air Samples Continuous air samples are collected weekly from two stations. Air particulate samples are collected on 47 mm. plastic filters. Air iodine samples are collected using charcoal absorbers mounted in tandem with the air particulate filters.

The sampling rate is one cubic foot of air per minute.

Liquid Effluent A split sample consisting of 3.5 liters of liquid effluent is collected quarterly at a point cloce to the discharge of'the Point Beach effluent channel. This sample is a grab sample and is collected while the plant is discharging liquid to the channel..

' Milk A one gallon sample of raw milk is collected monthly from the Funk Farm in Two Rivers. A raw milk sample is also collected monthly from the Lehnmann Farm located 2.5 miles northwest of the nuclear power facility.

4 Fish Both migratory and non-migratory fish are collected periodically from locations in Lake Michigan. tear the Point Beach-Kewaunee area.

Algae Algae growing on rocks ich ai a a part of the boat launching ramp at Two Creeks Park is harvested periodically for determination of gross beta activity.

Vegetation Vegetation in the form of grass is collected from several locations in the area of Foint Beach and Kewaunee.

ANALYTICAL PROCEDURES 1

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

Air Particulate Samples - Beta Gamma Place the 47 mm. plastic filter on a 2 inch stainless steel planchet. Beta count in a Widebeta I external gas flow proportional counter. Calculate activity correcting for counter efficiency.

Air Particu]Tte Samples - Gamma Place all of the 47 mm. plastic filters fc a month on the 4" x 4" NaI crystal detector. Determine the gamma spectrum asing 256 channels of an ND130A 512 channel gamma spectrometer set at 0.01 MeV per channel. Calculate activity correcting for counter efficiency.

Rain Water - Beta Gamma Evaporate a 500 ml. aliquot on a weighed 2 inch stainless steel planchet. Beta count in a Widebeta I external gas flow proportional counter. Calculate activi.ty correcting for counter efficiency.

I,

f" Lake Water - Alpha, Beta Gamma Filter 500 ml. aliquot of sample. Evaporate filtrate in a 2 inch stainless steel planchet. Beta and alpha count in a Widebeta I external gas flow proportional counter. Place filter paper in 2 inch stainless steel planchet and dry at 103 C.

Beta and alpha count in a Widebeta I external gas flow proportional counter.

Calculate activity correcting for counter efficiency.

Lake Water - Cesium 137 Place 3.5 liter sample in Marinelli beaker on 4" x 4" NaI crystal detector.

Count for 100 minutes on ND130A gamma spectrometer using 256 channels set at 0.01 MeV per channel. Calculate acti'rity correcting for counter efficiency.

Vegetation - Alpha, Beta and Gamma Isotopic Dry samples at 110'C, grind, weigh into stainless steel planchet. Beta and alpha count in a 3.debeta I external gas flow proportional counter. Calculate activity correcting for self-absorption and counter efficiency.

Prepare a similar sample of 6 grams and place into a 4 oz. graduated plastic container. Count for 100 minutes en a GeLi detector. Determine the gamma spectrum using 4096 channels of the 4096 channel gamma spectrometer set at 0.5 Kev per channel. Calculate the activity correcting for counter efficiency.

Milk - Cesium 137, Iodine 131 Gamma Scan Procedure same as for Lake Water - Cesium 137.

Milk - Iodine 131 - Chemical Extraction A stabile iodine carrier is ad?ed 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 NaOCl. After reduction to I by hydroxylamine hydrochloride, 2

l the lodine is extracted into CC14, reduced with bisulfite, and back extracted into water. The iodine is precipitated as palladous iodide with the chemical yield determined gravimetrically and counted in a Widebeta I counter correcting for counter efficiency and decay.

Milk - Strontium 90 Strontium and yttrium carriers are added to milk which has been aged two to four weeks. A one liter sample is passed successively through cation and anion exchange columns. The yttrium is eluted from the anion resin with hydrochloric acid and precipitated as yttrium oxalate, filtered and weighed to determine yield and beta counted in a Widebeta I counter correcting for counter efficiency and decay.

Fish - Beta Gamma, Gamma Isotopic Whole fish are put through a meat grinder and the ground fish well mixed. A representative fish sample of five grams in weighed into a stainless steel planchet.

The samgle is dried at 110 C and then ashed by slowly bringing the temperature to 550-600 C.

Beta cor.nt in a Widebeta I external gas flow proportional counter.

Calculate activity correcting for counter efficiency.

A 50 gram sample is ashed in a similar manner.

Place the sample on a GeLi detector and count for 100 minutes. Determine the gamma spectrum using 4096 channels of the 4096 channel gamma spectrometer set at 0.5 Kev per channel.

Calculate the activity correcting for counter efficiency.

Algae - Beta Gamma Five to seven grams of wet algae are weighed into a two inch stainless steel planchet. The sample is dried at 110 C and ashed at 550-600 C.

Beta count in a Widobeta I external gas flow proportional counter. Calculate activity correcting for counter efficiency.

Direct Radiation Thermoluminescent are supplied under a subcontract by the Eberline Corporation, Santa Fe, New Mexico. The dosimeters are read by Eberline and the data is reported to the State Radiation Protection Section.

CONCLUSIONS The air particulate filters showed a small 14mrease in gross beta activity during the months of November and December. The increases in activity were two or three times the normal levels of previous years.

Increases in beta activity were also noted at other monitoring stations around the state and these increases are probably attributable to radioactive fallout from an atmospheric weapons test conducted by the Chinese on October 6, 1980. Analysis for air radioiodine and gamma isotopic analysis on composite air particulate filters detected no unusual activity above the levels seen in previous /aars.

I Analysis of environmental samples such as. surface water, milk and fish detected no unusual activities. Radioactivity levels were consistent with prior years' data.

Necessary Wiscoasin data that is missing is due to problems associated with the laboratory that the State of Wisconsin contracted with for the analysis of the environmental satugies.

The contracting laboratory did not perform the required analyses due to difficulty in obtaining qualified personnel and has experienced i

difficulty with timely reporting of the required analyses causing this report to be late. - -

4 Missing data from 1979 has not been received from the contracting laboratory and much of the data is lost due to the aging of samples which contain'd isotopes of very short half lives, i.e.,

Iodine 131. Milk analysis for Iodine 131 during 1980 has not been reported to the required lower limit of detection since the chemical procedure was not performed on the samples.
