核电站放射性气溶胶探测器入射粒子模拟分析

摘要

分析了核电站放射性气溶胶的分类及来源,利用SRIM模拟计算软件模拟了探测器测量α射线的真实物理过程,分析计算了放射性气溶胶发射的α射线在进入探测装置前的运动行为,为放射性气溶胶探测装置的设计和研制提供了理论数据指导.%In this paper, the sort and origin of radioactive aerosol in nuclear power plant were analyzed. The real physical process of how to detect a-particle was studied with simulation software SRIM. Behavior of a-particle emitted by radioactive aerosol before it enters into detecting device was analyzed also, gave theoretic data advices for design and manufacture radioactive aerosol detecting equipment.
