摘要
采用EGS5蒙特卡罗程序计算了γ射线穿过UF6材料后的周围剂量当量累积因子。计算给出了50 keV~3MeV范围,1~10平均自由程下的光子周围剂量当量累积因子,并给出了与计算值符合度较好的参数化拟合公式。计算结果将便于采用线性减弱系数对涉及UF6材料的剂量计算。
In this study, EGS5 Monte Carlo code was used to calculate the buildup factor for ambient dose equivalent due to the passing of gamma-ray through uranium hexafluoride with photon energy range of 50 keV to 3 MeV and depth of 1-10 mean free path. The fitted formulae were also given based on Origin software for cal- culating ambient dose equivalent related to UF6 material. The results from fitted formulae show a good agree- ment with calculated values.
