本論文では、福島県が開設した電話による住民問い合わせ窓口への協力の一派遣者としての実践経験に基づき、放射線に関する質問内容とその時系列的な変遷を分析する。その結果に基づき、事故直後のリスクコミュニケーションにおいては、リスク認知の進展に応じて、リスクの大きさだけではなく、それに対して有効な対処方法を伝えていくことが重要であるといった教訓を報告する。

This paper analyses change of questions on health effect by radiation during six months after Fukushima nuclear accident in terms of time based on an experience of risk communication in the call center of Fukushima prefecture for the accident of Fukushima Daiichi Nuclear Plane. The results show that main questions of the moment underwent a gradual transition from those for acquisition of information on situation of radiation contamination to those for way of acting to measure themselves for escape, decontamination and future health management. These changes may be caused due to progress risk perception, followed by awareness of risk, formation of risk image, estimation of risk and risk control on health effect of radiation in turn. The results also show that the function and method of risk communication required by the moment would undergo a gradual transition according to progress of risk perception.
