Content:
f 1 to 3 of the nearest water supplies that could be affected by its discharge Composite sample over 2-week period(I) if I-131 analysis is performed, monthly composite otherwise I-131 analysis on each composite when the dose calculated for the consumption of the water is greater than 1 mrem per year. Composite for gross beta and gamma isotopic analyses monthly. Composite for tritium analyses quarterly 1 sample from a control location Sediment from Shoreline 1 sample from downstream area with existing or potential recreational value Semiannually Gamma isotopic analyses semiannually RADIATION BY INGESTION Milk Samples from milking animals in 3 locations within 5 km distant having the highest dose potential. If there are none, 1 sample from milking animals in each of 3 areas between 5 to 8 km distant where doses are calculated to be greater than 1 mrem per year Semiannually when animals are on pasture; monthly at other times Gamma isotopic and I-131 analysis semiannually when animals are on pasture; monthly at other times 1 sample from milking animals at a control location (15-30 km distant and in the least prevalent wind direction) Fish and Invertebrates 1 sample of each commercially and recreationally important species in vicinity of discharge point Sample in season or semiannually if species is not seasonable Gamma isotopic analysis on edible portions 1 sample of same species in areas not influenced by plant discharge Table 6.2-2. Radiological Environmental Monitoring Program (contd) Exposure Pathway and Sample Number of Samples(a) and Locations Sampling and Collection Frequency(a) Type and Frequency of Analysis NUREG-1555 6.2-8 October 1999 Food Products 1 sample of each principal class of food products from any area that is irrigated by water in which liquid plant wastes have been discharged At time of harvest(k) Gamma isotopic analysis on edible portion. I-131 analysis on green leafy vegetables 3 samples of broadleaf vegetation grown nearest an offsite location
