Nuclear Regulation Authority establishes study team on “evacuation indoors” in case of nuclear power plant accident. Residents within a 5km to 30km radius should evacuate indoors to their homes or other locations.
It is said that evacuation will occur if the radiation dose exceeds a certain value. The study team is made up of two members of the regulatory commission, nuclear disaster prevention personnel from the Cabinet Office, officials from local governments where nuclear power plants are located, and outside radiation experts.
