Some radioisotopes introduced into the Columbia River via effluent water from reactors at Hanford, Wash., are found in crops irrigated with this water and in sea food harvested near the mouth of the river. Measurements of zinc-65 and chromium-Si in foods and in individuals consuming these foods are reported and are compared with zinc-65 concentrations resulting from fallout.
