Practice of Community-Based Risk CommunicationFormer faculty member, University of Fukui, Naoki Yamano A new methodology of community-based risk communication was developed in cooperation with the local community by targeting the risks associated with the health effects of exposure to low-dose radiation after the Fukushima Daiichi Nuclear Accident. Before and after the study sessions that were conducted for three years as a joint pilot program with the citizens of Tsuruga, attitude surveys were conducted to analyze changes in the participants' knowledge, risk perceptions, and attitudes with respect to radiation, thereby validating the effectiveness of the methodology used for community-based risk communication. This commentary examines communitybased risk communication with reference to the matters discussed in the public forum on the health effects of exposure to low-dose radiation that was held in Ookayama in March 2016.
