If an accident occurs at a nuclear power plant and if it affects, or is anticipated to affect, the environment by radioactive material release, it is important to minimize consequences to the public by conducting appropriate protective measures, in evaluating source terms (an amount of fission products released to the environment), environmental radiological consequences, effects of the protective measures, and so on. It is also important to give necessary information on the protective maesures to the public so as to conduct the measures effectively. In order to support radiological emergency response measures and to contribute to improve emergency plans, the Japan Atomic Energy Research Institute (JAERI) is developing 1) a computerized support system for the Emergency Technical Advisory Body and 2) a computerized system for optimizing off-site emergency protective measures, and is studying appropriate information transmission methods in an emergency. This report describes current status of research on emergency response measures performed at JAERI.
