Namie Town in Fukushima Prefecture, the majority of which was an evacuation area as a result of the effects of the Fukushima Daiichi Nuclear Power Plant accident, carried out a 'temporal stay' in September 2016 so that residents could check their houses. Therefore, in cooperation with the town authorities, the authors distributed personal dosemeters and behaviour record forms to record the personal dose equivalent rate and investigate the relationship between residents' external radiation dose and their behaviour. When the personal dose equivalent rate was calculated from the measured personal dose equivalent per hour, the median was 0.12 μSv h-1, the maximum value and the minimum value were 0.58 and 0.06 μSv h-1, respectively. Meanwhile, since personal fluctuations were observed in personal dose equivalent, grasping the relationship between residents' behaviour and exposed dose can be applied to risk communication.
福岛县浪江町的大部分地区因福岛第一核电站事故的影响而成为疏散区，该町于2016年9月实施了“临时居住”，以便居民检查自己的房屋。因此，作者与镇政府合作，分发了个人剂量计和行为记录表格，以记录个人剂量当量率，并调查居民外部辐射剂量与其行为之间的关系。当根据每小时测量的个人剂量当量计算个人剂量当量率时，中位数为0.12 μSv h-1，最大值和最小值分别为0.58和0.06 μSv h-1。同时，由于在个人剂量当量中观察到个体波动，掌握居民行为与暴露剂量之间的关系可应用于风险沟通。
