摘要
本文根据γ射线与物质相互作用机理,建立基于蒙特卡罗方法的粒子输运数学模型。根据窄束γ射线在物质中的衰减规律公式,通过蒙特卡罗方法模拟计算得到不同能量γ射线对于不同材料的衰减系数。并对γ射线在几种物质中的能量衰减变化进行模拟。结果显示用蒙特卡罗方法模拟与理论完全吻合。
According to the interaction of gamma ray and material mechanism, a Monte Carlo method based on particle transport model. According to the attenuation formula of narrow beam of gamma rays in matter, by means of Monte Carlo simulation for different energy gamma ray attenuation coefficient of different materials are obtained. And the energy gamma rays in several substances in the attenuation change simulation. The results showed that using Monte Carlo simulation method coincides with the theoretical.
