The accident at the Tokyo Electric Power Company (TEPCO) Fukushima Daiichi nuclear power plant on March 11, 2011, released a large amount of radioactive materials resulting in the radioactive contamination of a wide area of eastern Japan. Residents of the Fukushima prefecture experienced various unavoidable damages and fear of radiation effects on their health. A reliable communication of accurate risk assessment for residents is required as a countermeasure aimed at the reconstruction of Fukushima. Here, the current status of individual dose estimation and the issues relating to the radiation risk perception are discussed.

From October to December 2010, just before the radiological accident at the Tokyo Electric Power Company Fukushima Daiichi nuclear power plant, 71 radiation professionals belonging to the radiation facilities in Japan were asked what they consider as a "safe" dose of radiation for themselves, their spouse, parents, children, brothers and friends. Although the "safe" dose varied widely from less than 1 mSv/y to higher than 100 mSv/y, the average dose was 35.6 mSv/y that was around the middle point between the exposure dose limits for annual average (20 mSv/y) and for any single year (50 mSv/y). Similar results were obtained from another surveys for the members of Japan Radioisotope Association (36.9 mSv/y) and for the Oita Prefectural Hospital (36.8 mSv/y). Among the family members and friends, the minimum average "safe" dose was 8.5 mSv/y for children, to whom 50% of responders claimed the "safe" dose less than 1 mSv. Gender, age and specialty of the responder also affected the "safe" dose. These findings suggest that the perception of radiation risk varies widely and that the legal exposure dose limit derived from the regulatory science may act as an anchor of safety even in radiation professionals. The different level of risk perception for different target groups in radiation professionals appears similar to those in non-professional whole population. The gap between these characteristics of real radiation professionals and the generally accepted picture of radiation professionals might take a part in a state of confusion after the radiological accident.

東京電力福島第一原子力発電所事故以来,医療スタッフに対する放射線教育の拡充が求められているが,その中心的存在となる医師の放射線に関する知識の程度は明らかではない。本研究では,医師としてのスタートラインに立った臨床研修医のオリエンテーションにおける放射線研修時に確認問題とアンケートを実施し,放射線の理解とリスク認知の状況を調べた。その結果,放射線の理解度では放射線の健康影響,次いで放射線の基礎と安全取扱いについて高く,放射線関連の諸規則や規制科学は全般に低かった。しかし,いずれの分野においても,よく質問されやすいようなごく基本的な内容において,理解度が低いものが見られた。放射線に関連したリスク認知度は,X線検査の受診と放射線診療の実施に対する認知は「リスクは気にしない」程度,その一方,原子力発電と原発の近隣地域での居住については「リスクがあるのでなるべくなら避けたい」レベルで,いずれも福島原発事故後の時間経過にかかわらずほぼ一定を示した。以上の傾向は,従来の他の職種や学生によるリスク認知分布傾向と同様であった。研修医が今後,専門性を獲得していくにともない理解度とリスク認知度も多様化することが考えられるため,継続的かつ反復的な基本的事項及び最新トピックスの研修の必要性が示唆された。
