| 摘 要： | 利用蒙特卡罗程序EGS4，针对几种特定的γ光子谱，计算了特定形状的LiF固体电离室中空腔辐射敏感元件LiFTLD的吸收剂量-光子注量转换因子；计算结果表明，该转换因子的不确定度主要取决于谱的不确定度；通过对单能光子源的蒙特卡罗计算结果与解析公式计算结果的比较，证明该方法是可靠的，是目前解决此类问题的有效而可行的途径。

| Abstract: | The dose to fluence conversion factors for the radiation sensitive element LiFTLD of a LiF ionization chamber are calculated with EGS4 code system when incident photons consist of different energy spectra. Calculation results show that the uncertainty of conversion factors is determined by the uncertainty of the energy spectra. The comparison of the two results obtained by analysis equation and EGS4 separately for mono energetic incident photons indicates that it is stable and reliable to use the Monte Carlo method to solve such kind of problems . |
