摘要
蒸汽发生器传热管破损的氮１６辐射监测对核电站安全运行具有重要意义．文中建立了γ光子与探测器介质作用的简化数学物理模型，采用蒙特卡罗方法和间接处理技术对ＮａＩ探测器效率因子Ｋ１２进行了数值计算．计算结果与文献资料提供的数据符合较好，与直接处理方法比较，间接处理可大大缩短ＣＰＵ时间．
A simplified mathematical model for reactions between photons and detector medium is presented.By using the Monte Carlo method and indirect treatment method the NaI detector efficiency factor K 12 is calculated.The computational results well agree with the data in the reference.Compared with the direct treatment method,the indirect treatment method can greatly reduce the CPU time.
