ecified portions of the regulations. Table 6.2-2. Radiological Environmental Monitoring Program Exposure Pathway and Sample Number of Samples(a) and Locations Sampling and Collection Frequency(a) Type and Frequency of Analysis AIRBORNE Radioiodine and Particulates Samples from 5 locations: Samples from 3 offsite locations (different sectors) of the highest calculated annual average D/Q. Radioiodine canister: analyze weekly for I-131 1 sample from the vicinity of a community having the highest calculated annual average D/Q. Continuous sampler operation with sample collection weekly or as required by dust loading, whichever is more frequent(d) Particulate Sampler: Gross beta radioactivity following filter change,(b) composite (by location) for gamma isotopic(c) quarterly 1 sample from a control location (15-30 km distant and in the least prevalent wind direction)(e) DIRECT RADIATION(f) 2 or more dosimeters or 1 instrument for measuring and recording dose rate continu- ously to be placed at each of the same locations as for air particulates and at each of 3 additional offsite locations (different sectors) of highest calculated annual average ground-level χ/Q. Monthly or quarterly Gamma dose monthly or quarterly WATERBORNE RADIATION Surface(g) 1 sample upstream 1 sample downstream Composite sample over 1-month period(h,i) Gamma isotopic analysis monthly. Composite for tritium analyses quarterly Ground Samples from 1 or 2 sources only if likely to be affected(j) Quarterly Gamma isotopic and tritium analysis quarterly Table 6.2-2.
