摘要 本文采用蒙特卡罗程序EGS5模拟计算单位注量的10keV~10MeV的光子在空气中所产生的空气比释动能,并将计算结果拟合成公式。模拟计算结果与ICRP74号报告中建议值的相对偏差在±2.0%以内,与ICRU47号报告中建议值的相对偏差在±3.5%以内;拟合值与前者的相对偏差在±4.0%以内,与后者的相对偏差在±7.0%范围内。 The conversion coefficients for air kerma from photon fluence were calculated using Monte-Carlo code EGS5 with photon energy range from 10 keV to 10 MeV.The calculated results of Monte-Carlo simulation show good agreement with the data recommended by ICRP74,ICRU47 reports within ±2.0%,±3.5%,respectively.The calculated results were fitted to a parametric formula.The values of the formula were in agreement within ±4.0%,±7.0% compared to the data recommended by ICRP74,ICRU47 reports,respectively.
