EFFECT OF FLOW AVERAGING PERIOD ON NORMALIZED CONCENTRATION (DATA - KANKAKEE RIVER 1961) k Many alternative schemes for developing water resources may have been proposed in a particu lar region, and it Is difficult to conclude which, if any, are likely to be constructed. The evaluation described herein should consider any Federal, state or locally authorized projects; any projects adopted by local river basin commissions; or any other projects whose chances of being constructed are considered likely. The locations of fisheries and recreation areas that will be exposed to normal releases of radionuclides within 50 radial miles of a plant should be identified. Present and projected future contact by humans and fish should be estimated. The use of
