摘　　要：蒙特卡罗软件在粒子输运相关研究中有广泛应用。文章通过Geant4软件,对伽玛射线在不同厚度铅屏蔽体下屏蔽效果进行了模拟。通过得到的衰减倍数曲线,与国际标准的衰减倍数曲线、实验得到的衰减倍数曲线相对比。结果表明:理论与模拟的曲线符合较好,与实验数据符合度较差;在一定情况下,Geant4软件在研究上更具有优势,使用Geant4软件可以代替实验,效果更好。Monte Carlo software is widely used in particle transport related research.This paper uses Geant4 software to simulate the shielding effect of gamma ray under different thickness lead shielding.This paper uses Geant4 software to simulate the shielding effects of gamma rays on different thickness lead shields.The obtained attenuation multiple curve is compared with the international standard attenuation multiple curve and the experiment obtained attenuation multiple curve.The results show that the theoretical and simulated curves are in good agreement with the experimental data.The Geant4 software has more advantages in the research.The use of Geant4 software can replace the experiment and the effect is better
