[Event]International Mini Workshop on Low Dose and Low Dose-Rate Radiation Research -Current Status and Future Prospects-

National Institutes for Quantum Science and Technology (QST) is a national corporation and mission of National Institute of Radiological Sciences (NIRS) includes medical application of radiation, radiation effects, radiation protection and radiation emergency medicine. There are important issues for radiation effects, especially decreasing uncertainty of risk estimation of low dose/low dose-rate radiation exposures. Desirable approach is to establish mechanistic and numerical model based on stem cell biology and radiation biology at high dose rate, and then to underpin the selection of appropriate risk model of chronic exposures. In order to carry out the research steadily and continuously, it is necessary to promote collaboration among stakeholders and establish all-Japan network among regulators, academia and research institutes. NIRS set up committee in 2016, and the committee summarized those results on the report about the network; name is Planning and Acting Network for Low Dose Radiation Research (PLANET). The PLANET will identify priorities of research needs and propose strategies to improve quantitative estimation of low dose/low dose-rate radiation risk. In addition, this network will propose support system for cooperation and collaboration research among related researchers and institutes in Japan. This cross-sectoral network should also aim to work together with international organizations and cooperation both in Japan and abroad will be promoted.
