Healy, J.W. ed.

No definite pathological damage was observed in fish fed 0.006 muc and 0.06 muc phosphorus-32 gram body weight per day, although a reduction in growth rate occurred at the 0.06 muc level. Pathological damage was evident at the lethal feeding level of 0.06 muc. Damage to the gastrointestinal tract involved all segments with equal frequency and ranged from mild damage to the epithelium at three weeks to severe damage and breakdown of the mucosa after 15 weeks. Pathological changes were also observed in the kidneys, liver, and spleen. Progress is reported in the following studies: the effeots of chroric ingestion of low levels of iodine131 in sheep and swine; the tissue distribution of single oral doses of strontium-90 in swine; blood volume determinations in swine of various ages and weights; the rotention of a single dose of strontium-90 and calcium45 in mature rats as influenced by the total calcium level of the diet; the tissue distribution of zinc-65, tungsten-185, and phosphorus-32 in rats, with emphasis on the relatively high radiation dose from phosphorus32 in the ovary when compared to bone; the pulmonary deposition and development of lung tumors in mice following intratracheal administration of ruthenium-106; the effectiveness of various aerosol treatments in removing Ru/sup 106/ O/sub 2/ particles from the pulmonary tract; the effect of variation in the strontium--calcium ratio on uptake of strontium-90 and calcium-45 by plants; the uptake of zinc-65 by plants irrigated with undiluted reactor effluent; radiobiological monitoring of the Columbia River and environs; the measurement of the vertical profiles and of the integrated cross-wind concentrations of airborne tracer materials used in diffusion and transport studies; routine monitoring activities; detailed duplicate activation analyses of tbe various materials which could contribute to the radioisotope level in the reactor effluent water; a test of the ability of a column of alumuinum turnings to remove radioisotopes from reactor effluent; determinations of the radiationprotective ability of various anionic groups in aqueous solutions; a survey of surface features of tbe basalt bedrock beneath the Hanford waste disposal area; ground waste disposal studies; and fission product volatility studies.
