Sharing of data archive of radiation exposure animal experiments in QST/NIRS and IES.

Institute for Radiological Science (NIRS), National Institutes for Quantum Science and Technology (QST), and Institute for Environmental Sciences (IES) have conducted large-scale animal experiments for radiation risk analyses in terms of life shortening and cancer prevalence. It is important to store data and biological samples from these large-scale experiments for sharing and future use since the economic and practical limitations, as well as the ethical considerations, make it difficult. QST/NIRS established an archive called the Japan Storehouse of Animal Radiobiology Experiments (J-SHARE) for the purpose of storing and sharing these historic collections. We plan to integrate the data and tissue specimen images obtained at the IES into J-SHARE by standardizing the archive format, with the aim of maximizing the results of radiation biology research. This integration is expected to contribute to the generation of new knowledge for radiation risk assessment and the provision of scientifically based information on radiation protection.
