Calculation of nuclide activity conversion factor for <italic>in</italic>-<italic>situ</italic> γ measurement Open
利用就地γ能谱测量结果评估环境放射性核素水平时，需要计算放射性核素比活度与γ能谱特征峰计数率之间的转化系数。转化系数计算本质上是对周围材料中不同空间位置放出γ射线的探测效率进行积分，但在复杂几何下积分式难以进行数值求解，限制了方法的使用范围。本文提出了一种蒙特卡罗模拟与数值积分结合的转化系数计算方法：通过蒙特卡罗随机抽样解决复杂几何积分问题，并通过输运虚拟粒子提升蒙特卡罗模拟效率。将方法应用于中国锦屏地下实验室（China Jinping Underground Labor…
