“…Such an accuracy assessment is essential information to be reflected in governmental policies. The Nuclear Regulation Authority adopted the developed method to evaluate the residents’ predictive exposure doses when the evacuation zone is lifted [ 1 ]. This method, defined as a lifestyle behavior model , is effective for predictive assessment, although its accuracy is lower than that of assessments based on actual measurements.…”

“…In 2017, the local government designated a specific reconstruction reproduction base area (SRR zone) to accelerate the recovery and revitalization of the difficult-to-return areas as shown in Fig. 1 [ 1 ]. The central and local governments are working together to create an environment conducive for residents to return to their homes and lift the SRR zone between 2022 and the spring of 2023.…”

The evacuation order areas established due to the accident at the Tokyo Electric Power Company Holdings’ (TEPCO) Fukushima Daiichi Nuclear Power Plant (FDNPP) have been reorganized according to the decrease in ambient dose rates and the decontamination progress. The Japanese government decided to decontaminate the difficult-to-return areas and lift the evacuation order by 2030. This radiation protection strategy can be optimized by examining emergency exposure situations to date and the existing exposure after the accident. This article reviews the methods that can determine the individual radiation doses of residents who should return to their homes when the evacuation order is lifted in the specific reconstruction reproduction base area and the difficult-to-return areas outside this base area and summarizes the points to be considered when implementing these methods. In Part 1 of this article, we review the efforts made by the Japanese government and research institutes to assess radiation doses to residents after the FDNPP accident.
