辐射消毒用电子束剂量场的研究

通过模拟跟踪2、3MeV电子在1cm纸层中的相互作用过程，记录统计电子及其辐射次级粒子在纸层及其周围环境的能量沉积。在假定病毒的致死当量剂量为200Sv的情况下，计算离柬靶不同距离的水介质（水模）的当量剂量。还给出了采用电子柬扫描传输带上的信件的方式，不同处理信件速率对加速器电子柬平均流强的要求。例如，要处理1t／h信件，要求2、3MeV电子柬流强为29、22μA。

Study of dose distribution from electron beam

In this paper, through the Monte-Carlo simulation, the interaction between electrons and material, a deck of paper and its surroundings, is traced. The deposit energy in the target is recorded when 2MeV and 3MeV electron beams pass through the deck of paper. To assume 200Sv could make virus in the paper die out, it is shown what intensity of electron beam we will need to deal for such as one ton of paper per hour rate. And we will get the surrounding radiation dose to make sure what kind of protection is needed to keep people safe.
