【摘要】：近年来,随着恐怖事件频发,利用放射性物质进行核恐怖袭击的可能性越来越大。其中,放射性"脏弹"事件是利用放射性物质扩散进行破坏的核恐怖活动,一旦发生,造成的后果将较为严重。分析了放射性"脏弹"可能的组成种类与作用效应,在此基础上模拟计算了典型场景下放射性"脏弹"的放射性剂量。按模拟所得平均值,烟羽吸入内照射途径是放射性物质作用于人体的主要方式,占平均总有效当量剂量的99%左右;而地面沉积外照射途径贡献了第二多的总有效当量剂量,地面沉积外照射与烟羽外照射只占总有效当量剂量的1%左右。同时分析了放射性"脏弹"对人体、环境可能造成的后果。
[Abstract]:In recent years, with the frequent occurrence of terrorist incidents, the possibility of using radioactive materials to carry out nuclear terrorist attacks is increasing. Among them, the radioactive "dirty bomb" incident is a nuclear terrorist activity which is destroyed by the spread of radioactive material. Once it occurs, the consequences will be more serious. The possible composition and action effect of radioactive "dirty bomb" are analyzed, and the radioactive dose of radioactive "dirty bomb" in typical scene is simulated and calculated. According to the simulated average value, the internal radiation pathway of plume inhalation is the main way for radioactive substances to act on the human body, accounting for about 99% of the average effective equivalent dose, while the surface deposition external irradiation pathway contributes the second largest total effective equivalent dose. Only about 1% of the total effective equivalent dose was caused by external irradiation of surface deposition and plume. At the same time, the possible consequences of radioactive "dirty bomb" on human body and environment are analyzed.
