Progress is reported in studies on the clinical aspects of radiation injuries in laboratory and domestic animals. Data are included on the status of burros surviving wholebody exposure to neutrons and gamma radiation in the lethal dose range; the status of swine surviving neutron and gamma exposure from an atomic detonation; a comparison of the toxic effects of Sr/sup 90/ amd Ra in sheep; the development of techniques for the visual observation of the cerebral hemisphere in irradiated sheep; studies on radiation tumorogenesis in rats and sheep; and the effects of actinomycin D on growth rate, blood picture, and LD/sub 50/30/ radiation response in rats. Three Hereford cows are reported surviving from a group of 60 animals exposed to radioactive fallout from the first atomic bomb test at Alamogordo, New Mexico, July 1945. Squamous cell carcinomas were removed from the area of BETA burns of one animal and autopsy findings are summarized for one animal that died in May 1962. Pathological findings included a squamous cell carcinoma in the area of BETA skin burn, malignant lymphoma, pancreolithiasis, neoplasia of adrenal medulla, and uterine cyst. Studies were continued on the effects of radiation on the reproductive cycle in large animals. Data are included on the effect of chronic irradiation on sperm production in bulls; and the effects of prenatal irradiation on anatomical development in calves, swine, and rabbits. Necropsies were performed on 57 cadavers from 4 species exposed to various radiation doses. Pertinent data are summarized on cows, burros, sheep, and swine. The metabolism of fission products and chemically related nuclides was investigated in beef cattle, sheep, swine, and poultry. Data are included on the effects of whole-body irradiation on the metabolism of Sr/sup 89/, Ca/sup 45/, and Se/sup 75/ in swine. Emphasis was placed on the pathway of fission product entry into milk and possible means of metabolic control. Studies were continued on soil properties that affect the availability of fission product elements to plant roots. Investigations were also continued on applications of radiation in plant breeding studies. Data are included on the influence of pregermination temperature and time on the radiosensitivity of dormant seeds of Nandina domestica, the effects of pre- irradiation humidity on the radiosensitivity of seeds, and the interaction of seed moisture with storage and oxygen effects on irradiated seeds. The radiosensitivity of carnation cuttings, tulip bulbs, and rooted cuttings of various ornamental plants such as Abelia, Pinus, Coleus, Forsythia, Rosa, and Ilex was investigated. Field scale mutation studies were made on plants from irradiated seeds of soybean and cotton. Seeds and other materials were irradiated for cooperators in the plant breeding program. A list is included of publications during the period covered by this report. (C.H.)
