摘　　要：应用蒙特卡罗方法模拟了60Co辐射成像系统检测射线束的准直过程。通过分析MCNP程序给出的计算数据,讨论了源室、准直器和侧屏蔽体在射线准直过程中的不同作用,对实现成像系统射线的准直具有参考价值。The Monte Carlo method is used to simulate inspection ray collimation process for 60Co radiography system. According to the calculating results given by MCNP program, the influence of source chamber, collimator and shielding sideboard to inspection ray are discussed. The results have referential value to realize collimation design for radiography system.
