摘要
本文综述了针对日本福岛核电站(FDNPP)事故后,早期阶段释放的放射性气溶胶的化学分析工作进展。内容主要涉及负载铯、钚、氙、碘等核素的气溶胶粒子。从粒子的取样与样品处理、粒子特性分析与表征、粒子输运与沉降行为、同类事故比较等角度,总结了事故后放射性气溶胶的部分物化特性与动力学行为。
The Fukushima Daiichi Nuclear Power Plant(FDNPP)accident was rated at the maximum level of 7on the International Nuclear Event Scale by the international society.This paper reviews the development of chemical analysis work for radioactive aerosols released during the early stages of the accident in many countries after the FDNPP accident,and reveals these aerosol particles bearing radionuclides,such as Cs,Pu,Xe and I.In this paper,some physical-chemical characterization and dynamic behaviors of radioactive aerosols with a few points,including particles sampling and collection,particles analysis and characterization,particles transport and deposition behavior,and identical accident comparison have been conducted.
