Reconstruction has progressed steadily since the 2011 TEPCO's Fukushima Daiichi Nuclear Power Station accident. However, some people still hesitate to eat foods from Fukushima or to travel there, and there are concerns about the health risks of radiation. We investigated the relationships among reconstruction-related behavior, risk perception, types of information, and information sources, in order to consider appropriate measures for providing information and promoting reconstruction-related behavior a number of years after the accident. We conducted an online questionnaire survey (n = 1000) of Tokyo residents. First, a factor analysis was conducted on knowledge associated with radiation. Two factors were extracted; namely, "physical knowledge" and "health/social knowledge." We conducted structural equation modeling to construct a model of "knowledge," "radiation risk perception," and "intention concerning reconstruction-related behavior." "Intention concerning reconstruction-related behavior" decreased with "radiation risk perception" and increased with "health/social knowledge." In addition, "health/social knowledge" negatively affected "radiation risk perception;" this effect was not large, but it was significant. Second, respondents were clarified by information sources using a cluster analysis. Clusters that included respondents who got information from public relations materials issued by municipalities and websites of administrative agencies had a higher factor score for "health/social knowledge" than other clusters. The cluster of respondents who did not get any particular knowledge had the lowest factor score, which was significant, and also had a low "perception of reconstruction."
自 2011 年东电福岛第一核电站事故以来，重建工作一直在稳步推进。然而，仍有一些人对食用福岛食品或前往福岛旅游犹豫不决，对辐射的健康风险存在担忧。为了考虑在事故发生多年后提供信息和促进与重建相关的行为的适当措施，我们调查了与重建相关的行为、风险认知、信息类型和信息来源之间的关系。我们对东京居民进行了在线问卷调查（n=1000）。首先，对与辐射相关的知识进行了因子分析。提取了两个因素，即“物理知识”和“健康/社会知识”。我们进行了结构方程建模，构建了“知识”、“辐射风险认知”和“与重建相关的行为意向”模型。“与重建相关的行为意向”随着“辐射风险认知”的增加而降低，随着“健康/社会知识”的增加而增加。此外，“健康/社会知识”对“辐射风险认知”有负面影响；这种影响虽然不大，但却是显著的。其次，通过信息来源对受访者进行了聚类分析。包括从市政府发布的公关材料和行政机构网站获取信息的受访者的聚类，其“健康/社会知识”的因子得分高于其他聚类。没有获得任何特定知识的受访者聚类的因子得分最低，这是显著的，而且对重建的认知也较低。
