' L-2 and then off one (1) hour. The filters are exchanged weekly and are analyzed after decay of radon daughters for gross beta with a Nuclear-Chicago low back-ground beta counter. These initial gross beta measurements are performed by VEPCO on-site and the results are confirmed by sending nine (9) samples per month (one from each location) to EiC where they are analyzed for gross beta with a Beckman Wide Beta I or Beckman Wide Beta I I low background beta counter.

Sensitivity is 0.05 pCi/m3 for one-hundred (100) cubic meter (m3) volume. (Table C-2)

Radiogas Inert gases, primarily isotopes of krypton and xenon, may be released in low concentrations and may cause a slight increase in the background radiation level. The mill irem dose (beta plus gamma) per month is measured using five l/8 11 x l/8 11 x O.OJ:;i 11 sol id Li F thermo luminescent dosimeters double sealed in plastic bags. These dosimeters are placed at locations shown in Table C-1 and Figure I. Prior to May 1970, a single dosimeter was placed at each station, but subsequent measurements were based on five dosimeters at each station.

Each dosimeter was read out using the Eberline Model TLR-5 reader. The com-bined thickness of both plastic bags is approximately 40 mg/cm 2 . (Table C-3)

Water Water samples are collected bi-monthly from the James River, locations 1, 2, 6, 9, and 10 in Figure 2. These samples are analyzed for gross beta. Due to the salinity of this water, an oxalate precipitation is performed and the pre-cipitate counted. A chemical recovery adjustment is made on sample before reporting results. Each river water sample is analyzed for tritium by 1 iquid scintillation counting. (Table C-4)

c-5 Milk Samples of milk are collected bi-monthly from four locations near the site (locations 6, 7, and 12 in Figure 1) with two samples from location number l.

Each sample is analyzed for Sr-90, Cs-137, and stable calcium. 1-131 analysis is performed by gamma spectrometry of a one 1 iter sample in a Mar Inell I beaker.

Sr-90 is separated from the milk with cation exchange resin, eluted from the resin and analyzed. Stable cesium Is determined and reported. (Table C-14)
