γ辐射多层组合屏蔽的蒙特卡罗方法模拟及其论证

Simulation and Verification of γmultilayer Shielding with Monte Carlo Method

摘要

摘要: 应用蒙特卡罗（MC）方法通用软件(MCNP4B程序)建立多层组合模型，模拟计算了γ辐射非均匀屏蔽的问题，比较研究各种组合方法以确定最佳的方案。同时对模拟结果与理论计算、实验测量三者进行综合分析，说明了三者结论的一致性，也说明了用MC方法来模拟非均匀屏蔽的可行性和多层组合屏蔽设计的实际意义。 In this paper， the multilayer model was established to calculate γradiation nonuniform shielding problem， and various combinations of methods were investigated to determine the optimal option. At the same time， the comprehensive analysis of the simulation results， the theoretical calculation and the experimental measurements show that the consistency among them. Practical significance is also shown that the application of Monte Carlo method to simulate the nonuniform shielding feasibility and multilayer shielding design.
