This week, Japan’s Nuclear Regulation Authority adopted new guidelines which expand evacuation areas from 10 kilometers to 30 kilometers around nuclear plants which would be set in place in the event of a nuclear accident. Previously 45 municipalities in 15 prefectures were located in designated evacuation areas, the new guidelines now cover 135 municipalities in 21 prefectures.
The central government has given local municipalities until next March to draw up nuclear emergency measures.
The new regulations are not complete, as many issues raised by local governments have been deferred until later this year, such as minimum doses of radiation requiring evacuation, the use of SPEEDI to forecast radioactive displacement, and pre-staged supplies of iodine tablets.
