摘要
利用加速器的工程CAD模型和MCNP计算文件获得的辐射剂量分布图,定性分析了加速器周围的辐射场分布,并结合国家相关标准GB/T20129-2015对加速器防护性能的剂量学相关指标进行了模拟计算和优化分析.研究结果表明在加速器初步设计的状态下,利用CAD精确建模和MC模拟计算的方式进行加速器防护性能指标的快速检测和评价具有一定可行性,并以此为基础进行加速器屏蔽结构、材料设置的优化.
The radiation dose distribution map obtained from the engineering CAD model of the accelerator and the MCNP calculation file was used to qualitatively analyze the radiation field distribution around the accelerator,and the dosimetry related indexes of the accelerator protection performance are simulated and optimized according to national standard G B/T 20129—2015.The research results show that it is feasible to use CAD accurate modeling and MC simulation calculation to quickly detect and evaluate the protective performance index of the accelerator under the condition of the preliminary design of the accelerator,and optimize the shielding structure and material setting of the accelerator.
