Activities of Environment and Radiation Sciences Division

Environment and Radiation Sciences Division conducts basic studies on the environmental science for the assessment of environmental impacts by radioactive materials discharged from a nuclear facility and on the radiation transport analysis for the accurate evaluation of radiation impacts on human and materials. In the environmental science research, computer simulation models for material transport in the atmospheric, terrestrial, and oceanic environment and methods for field measurement and experiment are developed, and the mechanism of material transport in the environment is elucidated by the combination of these technologies. As an application of our research to the global environmental problem, we participate in a project “Research on climate change using nuclear technology” of the Forum for Nuclear Cooperation in Asia (FNCA), and lead this research in Japan. In the radiation transport analysis research, computer simulation technologies based on the Particle and Heavy Ion Transport code System (PHITS) are sophisticated, and the dose evaluation method optimized for radiation protection is developed. Moreover, wide range of application researches are carried out in collaboration with domestic and overseas researchers.
