基于mcnp5程序研究60Coγ射线的剂量增强效应
摘要
用蒙特卡罗方法研究了金和硅交界时60Coγ射线入射产生的剂量梯度分布
并且通过mcnp5程序建立了一个三维的金硅界面结构模型
进而计算了剂量增强因子.计算结果表明:界面附近硅一侧具有明显的剂量梯度分布
界面剂量增强因子为1.76.
Abstract
In this paper the gragient distribution of dose with60Coγ-ray has been studied at and near the interface of Au/Si by Monte-Carlo simulation of particle transportation.A 3D Au/Si model has been established by mcnp5 program
and dose-enhancement factor has been also calculated. The caculated results demonstrate that there exists a stronger dose-enhancement in the Si side near the interface. The interface's dose-enhancement factor is 1.76.
