Project : Environmental Radiation   PurposeMembersPlansActivities >> Purpose We are to investigate distribution of the environmental radioactivity, to apply the results to the environmental impact assessment to health, and to establish the method to monitor the environmental radioactivity against emergencies of nuclear accidents and nuclear attacks. We are to investigate biological effects of high LET radiations experimentally and theoretically including alpha particles, which is about half of the public environmental equivalent dose. << Return Members Isao Yoshikawa* Professor, Environmental Conservation and Planning Course, Graduate School of Environmental Studies Toshihiro Takatsuji Associate Professor, Environmental Conservation and Planning Course, Graduate School of Environmental Studies *Responsible Scientist. << Return Plans Research about environmental radioactivity and radiation. Research of biological effects and dose rate effects of particle radiation. << Return Activities Summer school of environmental radioactivity and radiation was held from August 6 to 8, 2003 in Kawatana town, Higashisonogi-gun, Nagasaki. The contents were as follows: Discussions about measurements of the world wide environmental radioactivities and radiations by domestic outstanding scientists, and educational seminars for graduate and undergraduate students. A collaborative study with the National Institute of Radiation Sciences on "Spectrum of mutations induced by heavy particle radiations." A part of the results of the study was reported as entitled " Effect of high dose rate and low dose rate in exposure of low dose heavy particle radiation" at the workshop Summarization of Ten Years Cooperative Biological Research and Problems in future held from October 31 to November 1, 2003 at the National Institute of Radiation Sciences, Chiba. << Return
