| 摘 要： | 为预测"脏弹"恐怖袭击的破坏后果,建立了"脏弹"恐怖袭击剂量评价模式,总结了可能用于袭击的放射源种类、可能照射途径和剂量估算方法,并采用常见放射源种类、放射源活度、风速以及大气稳定度等参数值,用Gauss烟团模型对3种典型放射性物质在大气中的扩散过程进行计算,模拟给出有效剂量随时间变化的分布。取相同参数值情况下,该文计算结果与Hotspot结果相符合。该方法适用于中国反恐应急平台,为中国应对"脏弹"恐怖袭击的管理与决策提供了参考,具有现实意义。

| Abstract: | A dose calculation method was developed for use in radiological dispersal devices(RDD) terrorist attacks.This paper summarizes possible radioactive sources,common sources activities,important exposure pathes,and dose estimation methods.A puff model is used to analyze representative airborne radiological contaminants to simulate effective dose distributions over time.The results,which are consistent with the results of Hotspot,provide detailed data for emergency decision-making in China for anti-terrorism em... |
