EVALUATION OF RADIOLOGICAL CONDITIONS IN THE VICINITY OF HANFORD, JULY- SEPTEMBER 1961
An evaluation of radiological conditions in the vicinity of Hanford for the third quarter of 1961 indicated only minor differences in calculated environmental exposures as compared with 1960 and the first half of 1961. The principal Hanford source of exposure continued to be identified with radionuclides in reactor cooling water discharged to the Columbia River. For indivduals who regularly drink Pasco sanitary water, ingest local fish and waterfowl, and consume produce from local farms, an intake of boneseeking radionuclides was estimated at about 40% of that recommended by the National Committee on Radiation Protection and Measurements (NCRP) as maximum for continuous intake by persons in the neighborhood of controlled areas. The dose to the GI tract from drinking Pasco sanitary water for the 12 months ending with September of 1961 was calculated as about 90 mrems, which amounts to 6% of the recommended maximum permissible limit. While not significant in terms of human exposure, fallout from nuclear detonations was clearly in evidence in September. (auth)
