The Radioisotope Research Center promotes research and education using radiation such as radioisotopes and X-rays. The Center manages radioactive materials and X-ray equipments, provides training in safe handling, and conducts basic research on the application and safe handling of radiation. Provision of experimental laboratory space and instruments in the controlled area for research using radioactive materials. Preparation of various radiation detectors and instruments for researchers including undergraduate students.From birth to present, life has been evolved with irradiations by many radiations from the ground, the atmosphere and the cosmos. In 19th century, human beings got artificial activities, and these activities got into the act with radiations. Our studies are to clarify the effects of the radiations on human beings, and to apply the radiations to life. And we also aim to educate students based on these results.
