我が国における放射性物質(核燃料物質,放射性同位元素,放射性医薬品等)の輸送は、核燃料サイクルの進展,医療分野での放射性物質の利用拡大等に伴って、その質的・量的な拡大が見込まれる。これに伴い輸送事故の発生頻度も自ずと増加することが予想される。このような中で、放射性物質の輸送事故における総合的かつ統一的な緊急時対応方策について、欧米諸国と比較しながら検討する。

Radioactive and nuclear material is used in Japan extensively in industry, medicine, electrical power generation and nuclear fuel cycle. Also many packages of containing radioactive and nuclear material are consigned for transport. In the near future, there are expected to expand the use and to increase in the frequency of incidents. We have researched for emergency preparedness and response of radioactive material transport in major countries, and made a comparison with Japan. Referring international aspects and recent trends, we considered some features to enhance emergency response capability in Japan.
