Abstract

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.

Other Abstract

 In this paper the gragient distribution of dose with 60Coγ-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.
