Lifting of evacuation orders and subsequent efforts in Japan

Abstract

With confirmation of the cold shutdown conditions of the nuclear reactors after the accident at Fukushima Daiichi nuclear power plant, the Japanese Government reclassified the areas under evacuation orders as follows: (1) difficult-to-return zones (>50 mSv y−1), (2) restricted residence zones (20–50 mSv y−1), and (3) zones in preparation for lifting of the evacuation order (<20 mSv y−1). The Government continued its initiatives towards reconstruction of Fukushima, and has lifted evacuation orders in Zones 2 and 3. In terms of radiological protection, the Government emphasised its policy of placing importance on individual dose, and promoted the assignment of consultants in each municipality.
