・Abstract:
After the Fukushima nuclear accident, we examined changes in risk perception regarding the radiation contamination of food and information-seeking behavior among residents of three regions progressively more distant from the disaster area, the Tokyo Metropolitan area to the Kansai area. We conducted a ten-wave panel survey and obtained data from 1,752 citizens six months to nine years after the accident. The results indicate that anxiety related to radioactive contamination, active information-seeking behavior, and avoidance of foods from affected areas decreased with time. Active information-seeking behavior and radiation-related knowledge were higher in the disaster-affected prefectures than in other areas. Conversely, avoidance of foods from affected areas was lower in affected prefectures than in the Kansai area. The credibility of government information increased from a considerably low level but did not reach the midpoint level. Multiple regression analysis, cross-lagged analysis, and structural equation modeling indicated that avoidance of foods from affected areas was promoted by anxiety related to radioactive contamination (experiential thinking/System 1) and inhibited by critical thinking attitudes (analytical thinking/System 2). Finally, we discussed the significance of risk literacy, which integrates risk-related knowledge, scientific literacy, media literacy, and critical thinking.

・日本語によるコメント:
被災県・首都圏と関西圏の市民を対象とした福島第一原発事故による食品の放射線リスクへの態度について、9年間にわたる10回の調査を行ったものです。9年の時間経過によって、市民の放射能不安、積極的情報探索行動、被災地産食品の回避は、時間経過とともに減少しました。分析の結果、時間経過による被災地食品を避ける傾向の低下は、促進要因である放射能汚染に関する不安（システム1）の低下と、抑制要因である批判的思考態度（システム2）の上昇によって説明できました。
