摘要
采用EGS5光子—电子蒙特卡罗程序计算了多种能量的光子以多种入射角照射到混凝土上时在各个方向角上所产生的散射系数,分析了模型的形状及材料厚度对散射系数的影响,EGS5模拟所得的散射系数与MCNP程序计算结果符合度较好,相对偏差基本均在5.0%以内。
This paper makes a calculation on the scattering coefficient of photon with muhi-energy shining on the concrete from each direction angle adopting EGSS photon-electron Monte Carlo method, and has an analysis on the effect of the model shape and material thickness on the scattering coefficient. The scattering coefficient obtained by EGSS simulation has a better conformity with the result calculated by MCNP procedure, and the relative deviation is basically within 5.0%.
