给出了中子－γ能谱测井中ＮａＩ闪烁探测器对γ射线响应函数的计算方法，计算了３×３ＮａＩ（Ｔ１）探测晶体对能量直到２５ＭｅＶ的γ射线的能量沉积谱和响应函数。计算结果与实验结果符合较好。
The calculation method of γ ray response function of NaI scintillation detector in neutron-γ spectrogram is given. The energy deposition spectrum and response function of 3 × 3NaI (T1) detection crystal to γ-ray energy up to 25 MeV are calculated. The calculated results are in good agreement with the experimental results.
