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.

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.
