SEMI-ANNUAL PROGRESS REPORT ON UT-AEC AGRICULTURAL RESEARCH , JANUARY 1- JUNE 30, 1963
One cow is reported surviving from the group of cattle exposed to radioactive fallout from the first atomic test at Alamogordo, N. Mex., in July 1945. The cow recently gave birth to a normal, healthy calf, which is the 15th calf in as many years. The status is reported for burros and swine surviving high-level, whole-body exposure to gamma radiation, neutrons, or mixed gamma and neutron irradiation. Data are included on the eHects of exposure to 500 r gamma radiation on spinal fluid pressure and the composition of cerebrospinal fluid in sheep. Research was continued on the effects of radiation on the reproductive cycle in cattle, sheep, swine, and rabbits. The death patterns of irradiated animals were related to examination of necropsies. Mammary tumor incidence in newborn female rats was found to be increased when they were injected with blood plasma concentrate from lethally irradiated donors. No significant increase was seen when rats were injected at six months of age. Data are presented from a study of fission product metabolism in beef cattle, sheep, swine, and poultry. Strontium-89, Sr/sup 90/, Ca/sup 45/, Zn/sup 65/, Mo/sup 99/ Ce/sup 144/, Pr/sup 144/, Se/sup 75/, and Co/sup 60/ were used as tracers in the studies. Emphasis was placed on comparative information between species and the interaction of known dietary factors in the species. Factors affecting the I/sup 131/ content in milk were also studied in dairy cattle. A study of the fission product chemistry of soils was continued to determine the soil properties that affect the availability of fission product elements to plant roots and the factors that can alter this quantitatively. Samples of dry and stratified seeds, dormant plants, and fungi growing on agar were irradiated. Results are presented from studies of factors that affect the radiosensitivity of seeds and other plant parts that can be used by plant breeders to increase the variability of plants. (C.H.)
