It is crucial to examine how risk perception, risk trade-off view, and provision of risk information affect demands for countermeasures against multiple risks after a nuclear disaster. We investigated factors associated with the perceived dread risk of radiation exposure or diabetes and the self-rated risk trade-off view. We examined how the risk perception, self-rated risk trade-off view, and provision of risk information affected the perceived magnitude of the risks and the demands for countermeasures. We distributed an online questionnaire to 2806 panelists aged 20–69 years in the Fukushima Prefecture in 2018 and received 1044 valid responses. Both the perceived dread risk of radiation exposure and diabetes was associated with evacuation experience and trustworthy sources of information. The self-rated risk trade-off view was associated with gender, occupation, educational background, trustworthy sources of information, and a diabetes diagnosis. The perceived magnitude of radiation risk and the demand for countermeasures were governed by the perceived dread risk of radiation rather than the types of information provided or the self-rated risk trade-off view. Conversely, the perceived magnitude of diabetes risk and the demand for countermeasures were associated with both the perceived dread risk of diabetes and the self-rated risk trade-off view. The provision of risk comparison information slightly enhanced the demand for societal countermeasures against diabetes. The perceived dread risk is more strongly associated with the perceived magnitude of the risk and the demands for countermeasures than provided information. Development of a self-rated risk trade-off view is useful for encouraging countermeasures against diabetes.

至关重要的是要检查风险感知，风险权衡观点和风险信息的提供如何影响核灾难后针对多种风险的对策要求。我们调查了与感知到的辐射暴露或糖尿病的可怕风险以及自我评估风险权衡观点相关的因素。我们研究了风险感知，自我评估风险权衡的观点以及风险信息的提供如何影响感知到的风险规模和对策要求。我们于2018年向福岛县2806名年龄在20-69岁之间的小组成员分发了在线调查问卷，并收到1044份有效回复。感觉到的辐射暴露和糖尿病的可怕风险都与疏散经验和可靠的信息来源有关。自我评估的风险权衡观点与性别，职业，教育背景，可信赖的信息来源和糖尿病诊断相关。感知到的辐射风险的大小和对策的要求取决于感知到的令人恐惧的辐射风险，而不是所提供的信息类型或自评估风险权衡的观点。相反，对糖尿病风险的感知程度和对策的需求与对糖尿病的感知恐惧风险和自我评估的风险权衡观点相关。提供风险比较信息会稍微增加对糖尿病的社会对策的需求。与提供的信息相比，感知到的可怕风险与感知到的风险大小和对策要求之间的关联更为紧密。
