摘要
本文利用光子和电子耦合输运MC程序的电子脉冲计数类型的能峰展宽模拟计算了NaI (T1)探测器的γ能谱,与实验测量的能谱符合较好。然后利用MCNP计算了NaI(T1)对不同能量γ射线的探测效率(峰总比),结果与实验值一致,验证了这种计算方法用于模拟NaI(T1)对γ能谱的探测效率是可行的。
In the article, Monte Carlo method for Photon-Electron' s coupling transport is used to calculate the γ spectra of NaI(T1) detector by peak broadening of electronic pulse height tally. Then the peak-tototal ratios in the NaI(T1) detector to various γ-ray are calculated, and the results are fit in well with the experiment data.
