摘要
采用蒙特卡罗软件建立点源球壳模型,快速计算得到能量在10 keV~10 MeV区间的30种单能γ射线在水中的有效作用距离;采用蒙卡软件程序的F6卡、F4卡结合FM4卡、*F8卡三种方法,计算得到参考人在水中浸没外照射条件下的单能γ射线和19种核素的放射性活度浓度-剂量率转换系数。计算结果表明,分别与采用MIRD模型的美国能源署FGR 12报告、FGR 15报告和采用体素模型的ICRP 144相比,相对偏差均在±10%以内,计算方法和结果可为工程上快速计算提供借鉴参考。
The point source spherical shell model was established by Monte Carlo software,and the effective distances of 30 mono-energy gamma rays with energies in the range of 10 keV-10 MeV in water were quickly calculated.Using three methods of Monte Carlo method F6 card,F4 card combined with FM4 card,∗F8 card,the radioactivity concentration-dose rate conversion coefficients of mono-energy gamma-rays and 19 kinds of nuclides for reference person water immersion were calculated.The calculation results show that the relative deviations are within±10%compared with the FGR 12 report and FGR 15 report of the US Energy Agency using the MIRD model and the ICRP No.144 using the voxel model.The calculation method can provide a reference for rapid engineering calculation.
