摘要
采用蒙特卡罗方法模拟γ射线在空气中的衰减过程。在考虑二次康普顿散射的基础上,研究其衰减规律,得出的结果与航空实测资料吻合较好。
A Monte Carlo model is used to simulate the γ-ray attenuation process in the air.Taking the secondary Compton scatter into account, the attenuation law is studied. The resultsare in good accordance with the data from the airborne γ-ray survey.
