福岛健康管理调查（包括外部剂量估算基本调查和四项详细调查）是在福岛第一核电站事故后启动的。基本调查是向福岛县居民询问事故发生后4个月内的行为的问卷调查，许多居民对问卷进行了回复。通过使用数字化的行为数据和计算机程序，其中包括每天的伽马射线剂量率地图后，事故估计个人的外部剂量。前4个月421,394名居民（不包括放射工作人员）个人外照射剂量分布为：62.0%<1 mSv; 94.0%<2 mSv; 99.4%<3 mSv。个体外部剂量的算术平均值和最大值分别为0.8和25 mSv。虽然大多数剂量估算研究是基于典型的疏散情景和在室内/室外花费的时间，但基本调查估算的剂量考虑到了个别不同的个人行为。因此，可以揭示一些没有遵循典型情景的个人的剂量。即使考虑到这种极端情况，估计的外部剂量一般都很低，预计与辐射有关的健康影响的发生率不会明显增加。
The Fukushima Health Management Survey (including the Basic Survey for external dose estimation and four detailed surveys) was launched after the Fukushima Dai-ichi Nuclear Power Plant accident. The Basic Survey consists of a questionnaire that asks Fukushima Prefecture residents about their behavior in the first four months after the accident; and responses to the questionnaire have been returned from many residents. The individual external doses are estimated by using digitized behavior data and a computer program that included daily gamma ray dose rate maps drawn after the accident. The individual external doses of 421,394 residents for the first four months (excluding radiation workers) had a distribution as follows: 62.0%, <1 mSv; 94.0%, <2 mSv; 99.4%, <3 mSv. The arithmetic mean and maximum for the individual external doses were 0.8 and 25 mSv, respectively. While most dose estimation studies were based on typical scenarios of evacuation and time spent inside/outside, the Basic Survey estimated doses considering individually different personal behaviors. Thus, doses for some individuals who did not follow typical scenarios could be revealed. Even considering such extreme cases, the estimated external doses were generally low and no discernible increased incidence of radiation-related health effects is expected.
