摘　　要：医用回旋加速器在我国有较大规模应用,为保证加速器运行期间的辐射安全性,运行前需要对加速器辐射影响进行相对精确的分析论证。以某19 MeV局部自屏蔽式医用回旋加速器及其机房为例,利用FLUKA软件建立靶系统、局部自屏蔽体及机房模型,设置粒子类型、能量、束流强度、束流损失率等参数,模拟了机房墙外、门外、屋顶上方的剂量率水平。通过将模拟值与实测值对比的方式,研究FLUKA软件在加速器辐射影响分析领域的应用效果。Medical cyclotron has a large-scale application in China,in order to ensure the radiation safety during accelerator operation,it is necessary to conduct relatively accurate analysis and demonstration of the radiation impact of the accelerator before operation.Taking a 19 MeV local self-shielding medical cyclotron and its computer room as an example,this paper uses FLUKA software to establish the target system,local self-shield and machine room model,sets the particle type,energy,beam intensity,beam loss rate and other parameters,and simulates the dose rate level outside the wall,outside the door and above the roof of the computer room.By comparing the simulated values with the measured values,the application effect of FLUKA software in the field of accelerator radiation impact analysis is studied.
