Based on the lessons of the Great East Japan Earthquake, disaster-prevention measures at the time of the nuclear disasters were significantly revised. Among them, estimation and evaluation of radiation exposure of local residents is one of the most important issues. This study propose some advanced method for estimating the radiation exposure of residents using Mobile spatial statistics (population statistics),which is estimated to throughout all time in Japan (24 hours, 365 days), as reference information of disaster prevention planning.
