| 摘 要： | 利用蒙特卡罗方法的MCNP程序对HPGeγ谱仪探测系统建模,做能谱模拟和放射性标准土壤的探测效率计算,并与实验测量能谱相比较。由此得出结论,用MCNP程序不仅可以获得与实验相同特征的γ能谱,而且对探测效率的计算结果与实验结果符合程度较为理想。

| Abstract: | The detecting system model of HPGe gamma spectra apparatus was established for simulation of energy spectrum and detection efficiency calculation of standard radioactivity soil by comparison with experimental detection spectrum. The results indicated that the detection of gamma energy spectrum by MCNP program had similar features to that of experiment, and calculated results of detection efficiency were identical with those of experiment. |
