摘要
本文讨论了一种用于安检CT系统射线防护设计的方法,采用基于蒙特卡罗方法的MCNP5软件,模拟设计了一套与安检CT系统主要参数一致的小型测试装置,通过对比分析实验测试数据和模拟计算数据,验证了采用的模拟计算方法和仿真模型的可靠性。将该方法用于安检整机CT系统的射线防护模拟计算,可有效指导整机CT系统的射线防护设计。
This paper discusses a method for radiation protection design of the security inspection CT system.MCNP5 software based on Monte Carlo method is used to simulate and design a set of small test device which is consistent with the main parameters of the security inspection CT system.The reliability of the simulation calculation method and the simulation model is verified by comparing and analyzing experimental test data and simulation calculation data.Applying this method to the radiation protection simulation calculation of the security inspection CT system can effectively guide the radiation protection design of the whole security inspection CT system.
