摘要
对NaI(Tl)探测器的γ能谱进行了MC模拟,模拟研究了不同源-探距、不同能量分辨率、不同模拟时间和平面源分布等条件下的137Csγ能谱。137Cs点源的模拟谱与实测谱的对比表明两者基本相符。
In this paper, we simulate a NaI(Tl) scintillation detector responses at different source-detector distances, energy resolutions of the detector and computer time, with models of a point ^137Cs source and a planar ^137Cs source. Measurement was performed with a ^137Cs point source and the NaI(Tl) γ-ray spectrometer. The MC simulated spectra and the measured data are in good agreement.
