Research Abstract

I. Physical and Chemical characterization, and behavior of long-lived radionuclides in the environment (1) Particle size distribution of radonuclides in air-borne dust by newly developed method was measured. (2) Concentration of low-level long-lived radionuclides was determined by Inductively Coupled Plasma-mass spectrometry (ICP-MS). (3) Dithiocarbamate-Chitin (DTC-chitin) was prepared and Tc and Ru was separated by using the DTC-chitin. (4) In the pacific ocean characterization of Pu and U was determined. Consequently, the physical form of Pu was similar to U while chemical property of Pu was differed from U and resembled Th.
II. Uptake of environmental radionuclides and effect (5) The chemical transformation based on the interaction of radiocobalt with coastal sandy sadiment and the uptake and elimination of the radiocobalt in both ionic and organic forms by mussel, Mytillissepta virgatus, as well as adsorptie behavior of the radiocobalt in the rearing seawater were studied under laboratory conditions. (6) Peculiar biological concentration of specific element by marine organisms was examined to clarify the behavior of long-lived radionuclides in marine ecosystem. (7) Transfer factors of the radioiodine in iodine form and methyliodide of soil-to-crops and atmosphere-to-crops were determined. These results indicate that the permeability into the plant tissues of methyliodide is significantly larger than that of iodine.
III. Characterization and assessment of dose contribution (8) Among the Japanese tissues analyzed, the highest concentrations of Po-210 and Pb-210 were observed in bone. The absorbed dose rate to the lungs due to smoking was estimate and the risk mortality from lung cancer caused by Po-210 in cigarettes is 9x10^<-6> for the Standard Model Smoker.
