Boneless roasts and roasts wtth bone were obtained from steers dosed orally with calcium-45 and strontium-90. An analysis of cooked meat samples showed that calcium-45 and strontium-89 moved from the bone into the meat and drippings durirg cooking. Progress is reported in animal metabolism studies using copper-64, phosphorus-32, molybdenum-99, cesium-134, calcium-45, strontium- 89, zinc-65, iron-59. selemum-75, and potassium-42. The effectiveness of ion exchange materials for removing cesium-134 and iodine-131 from milk was investigated. ion exchange treatment of milk did not cause any marked changes in nutnitive value. Progress is reported in studies on the influence of stable dietary barium, strontium, and calcium on the uptake of stable strontium and calcium by bone in chicks; the effects of dietary calcium, phosphorus. and vitamin Di on the uptake of strontium-89, calcium-45, and phosphorus-32 by bones in chickens: the effects of terephthalic acid on calcium-45 and strontium-89 absorption: the absorption of carbon-14 labeled linoleic acid in chicks: and the effects of radiation on reproductive physiology in farm animals and rats. The status is reviewed of burros and swine which survived gamma-neutron irradiation from an atomic detonation, burros exposed to sublethal doses of gamma radiation five years previously, and burros exposed to neutron-gamma radiation from a bare reactor. Data are included on weight, pathological findings, and physiological response of the animals. The toxicity of radium and strontium was compared in sheep and the LD/sub 50/30/, radiation dose was determined for Hereford cattle. Results are summarized from a number of stadies on the transmission of radioinduced mutations in plants. A list is included of publications during the period. (For preceding period see ORO-217.)
