Purpose of this study is to survey the difference of people's attitude about nuclear power plant and other risky events before and after the JCO nuclear fuel plant accident on the 30th of Sep., 1999 (the worst accident in Japan's troubled history with nuclear power). In this study, same questionnaire was conducted twice. First survey (before the accident) was conducted in Aug.-Sep., 1999. 905 subjects who lived in the Kanto district (Tokyo and neighboring prefectures) joined. The second survey (after the accident) was conducted in Oct., 1999. 61 subjects who lived in Tokyo and Ibaraki pref. (near the place of the accident) joined. In the questionnaire, subjects were asked about attitude for 10 risky events (traffic accident, earthquake, fire, environmental destruction, war, nuclear power plant, and so on) from 11 aspects (anxiety, riskiness, knowledge, control, legislations, familiar and etc..). In the next part (trade-off part), subjects were asked to choose opposite/approval attitude for nuclear power plant through 5 aspects: Cost (electric charges), Community Development, Convenience, Environmental Protection and Energy. As a result, there was the significant difference only in nuclear power plant before and after the accident, while no significant difference in other risky events. And in the trade-off part, there was no significant difference in attitude about nuclear power plant before and after the accident. From these results, it was suggested that people actually recognized the risk of nuclear power plant, but didn't show strong opposite behavior.
