Chiba (Japan) aut 1971 Document Type: Report Language: Japanese Subfile: NSA (Nuclear Science Abstracts) Work Location: Japan The annual report described the research for survey, technical cooperation, training, medical examination, management of the Tokai branch, and library service in 1971. As special studies from last year, the implantation of hematopoietic organs in the radio-medical field and the medical usage of neutron beams were studied. Cyclotron equipment for utilizing neutron rays is scheduled to be completed at the end of 1973. In this year the study was done by Van de Graaff accelerator. The subjects in this year were collection and management of gamma camera data and intestinal bacterial flora to insert into SPF mice. In the annual studies, there were 71 subjects including 7 new subjects in this year, and these subjects were studied independently with a long-term plan in 12 sections. Studies on survey in the sea, centering at the marine laboratory, were concerned with concentration of radionuclides in flsh, shell-flsh, and seaweeds by radioisotope tracer and quantitative analysis of stable isotope, development of monitoring method for radioactivity in the marine organisms, and estimation of radiation exposure dose in human body accompanied with radiation pollution at the coast. The research on the actual condition were done on survey of Bikini victims, survey of the working environment using uranium fuel, and national dose for medical radiation.

(ed.) V.A.; (radiation-genetic aspects) Pomerantseva, M.D. such as number of chromosomes, acids. ploidy, and molecular weight of nucleic ln a discussion of radioresistance it is pointed out that the resistance of cells and organisms to radiation varies with the sensitivity of genetic material in the cellular and ontogenetic cycles. Effects of short-term irradiation on populations including studies on fruit flies, algae, and Bikini Island populations are reviewed. Genetic load dynanaics in long-term irradiation of populations are also reviewed. Other topics considered are effects of ionizing radiation on populations of laboratory isin and genetic adaptation of populations to long-tearm irradiation.
