The Fukushima Dai-ichi nuclear power plant accident led to the dispersion of radioactivematerial by windthat resulted in soil and air pollution over a wide area. Even now, more than 150,000 people in Fukushimaprefecture are still relocated from their homes. In order to estimate how long such relocation might continue,we estimated radiation exposures for the 10 years following the accident that occurred on 12 March2011, using European model for inhabited areas (ERMIN) developed by a partnership of several Europeanorganizations. We validated the estimated results of long-term radiation exposure with the observeddata at 1, 2 and 3 years after the nuclear accident. We analyzed the deposition velocity and re-suspensioncoefficient using the observed data on air concentration, amount of falling dust and soil contamination,and compared them with the published data.
