Japan Atomic Energy Agency is proceeding with plans for the near surface disposal of low-level radioactive waste generated from research institutes and medical institutions in Japan. In order to dispose of the radioactive waste generated by the dismantling of the research reactor, it is necessary to evaluate the radioactivity concentration in the waste. We report on the status of study of radioactivity evaluation methods for dismantling waste generated from research reactors.
