It is important to consider and develop countermeasures against Radiological Dispersal Device (RDD) incident in an urban environment. In the U.S. functions of countermeasure against terrorist attack has been developed, maintained and disseminated to the public by conducting regular emergency exercises. Here, we review the full-scale emergency exercise against RDD incident in an urban environment (EMPIRE09) held at Albany in the State of New York in June 2009. The National Response Framework of the U.S. for nuclear and radiological incidents is also explained. Finally, as our recommendation to the domestic countermeasures against terrorist attack, analyses on the difference of emergency response frameworks between Japan and the U.S. and important items to be considered are provided for consideration of the state of countermeasure against RDD incident in an urban environment.

The first reprocessing pilot plant in Japan (Tokai Reprocessing Plant; TRP) has been operated since 1977 at Nuclear Fuel Cycle Engineering Laboratories, JAEA. General radiation protection in TRP is performed with continuous monitoring and sampling methods. The continuous monitors measuring -ray, neutron, particulate alpha and beta nuclides in the air are installed in the radiation controlled area as a central monitoring system to prevent from unnecessary exposure. Air and water effluents from the TRP are also monitored by continuous monitors or sampling methods to comply with regulations. In addition to this, environmental monitoring has been carried out to assess influences on public and environment by the plant operation. A feature of radiation protection and its recent relevant researches at TRP will be introduced in this presentation.

【課題】放射性物質で汚染した環境において、放射性廃棄物の発生や、作業者の身体汚染及び被ばくリスクが少ない、かつ、計測が迅速でリアルタイムな計測ができるレーザによる放射線測定方法及び装置を提供することを課題とする。 【解決手段】測定環境下にある放射線によって発生した放射線電離ガスに励起レーザ光を照射し、該放射線電離ガスによって発生するラマン散乱光を測定することによって、放射線の強度及びその存在位置を特定するレーザによる放射線測定方法であり、前記測定環境下の放射線の強度の測定が、元素毎に予め定められた散乱光スペクトル強度と元素濃度との対比基準によって放射線の強度を特定する放射線の強度測定手段を有することを特徴とする。
