摘要
作者利用蒙特卡罗方法 ,模拟计算了高纯锗γ谱仪对环境样品探测效率与γ射线能量、样品介质成份、密度及几何高度的关系 ,并与实验结果进行了比较 .结果表明 ,蒙特卡罗计算方法是进行高纯锗γ谱仪效率刻度的一种方便。
HPGe γ spectrometer detection efficiencies which changes with the γ energy and the components, the densities and the volumes of environmental samples have been calculated by Monte Carlo method and have been compared with the experimental results. The comparisons show that the Monte Carlo simulation calculation is a convenient and reliable method for the efficiency calibration of the HPGe γ spectrometer.
