摘　　要：为提高GM计数管的应用水平,基于Geant4软件设计GJ4105型GM计数管的探测效率模拟程序。通过实测灵敏度对模拟程序的正确性进行验证,依据模拟的探测效率结果计算的灵敏度与实测灵敏度偏差仅为0.5%。结果表明:Geant4的模拟结果可靠,可为GM计数管的设计提供一种行之有效、方便快捷的模拟手段。In order to improve the application level of GM counter, the detection efficiency simulation program of GJ4105 GM counter was designed based on Geant4 software. The correctness of the simulation program is verified by the measured sensitivity, and the deviation between the calculated sensitivity based on the simulated detection efficiency and the measured sensitivity is only 0.5%. The results show that the simulation results of Geant4 are reliable, which can provide an effective and convenient simulation method for the design of GM counter.
