Abstract	Artificial radionuclides, induced in water used as a coolant in the Hanford reactors, are discharged into the Pacific Ocean by the Columbia River. Gamma-ray spectrometric measurements show that levels of 65Zn decrease in both sediments and benthic animals with distance from the mouth of the river and with depth of water. Although 65Zn decreases rapidly in animals below 400 meters, it was detected to 2900 meter depths in animals but not in the sediments. Levels of 65Zn in benthic animals appear to be associated with depth, distance from the point source, position of the Columbia River plume in the surface waters, and ecology of the organisms. The bottom fauna is thought to be important in determining the distribution of induced radionuclides on the ocean bottom.
