Economic Considerations on the Revision of Emergency Response Measures for Nuclear Disaster in Japan

東電福島第一原発事故によって日本の原子力災害対策はその有効性を大きく問われ,事故の経験を踏まえた改変が行われてきた。それらの改変について考察する。それらの対策には多くの欠陥が認識されたが,基本的な枠組みは変わっていない。事故前と共通する原子力災害対策の基本理念について振り返り,放射性物質への曝露の防止と公衆の被曝リスクの受忍の限界に関して,その本質的性質を踏まえて考察する。After TEPCO Fukushima First Nuclear Power Station accident there have been amendments of emergency response measures for nuclear disaster, in Japan. Despite of changes in order to cope with widely acknowledged flaws in those measures, fundamental framework for disaster management have been almost unchanged. There are limits in their essential nature, to the abilities to prevent exposures to radioactive substances, and justification of general public's exposure to radiation due to the use of atomic energy
