摘要/Abstract

摘要： 近年来我国医用质子/重离子加速器治癌产业开始飞速发展。粒子加速器运行时会产生次级辐射从而危及环境、公众及工作人员的辐射安全,可靠的辐射屏蔽设计是装置运行时辐射安全的必要保障。本文简要分析了医用质子/重离子加速器辐射屏蔽设计的一般考虑因素;介绍了几种常用的屏蔽计算方法并给出了计算实例。本文的研究内容对未来将要建造的医用质子/重离子加速器的辐射屏蔽设计具有一定的参考意义。

Abstract: In recent years, the cancer treatment industry of medical proton/heavy ion accelerator in China has started to develop rapidly. Secondary radiation is produced when the accelerator is in operation, which endangers the radiation safety of the environment, the public and workers. Reliable radiation shielding design is a necessary guarantee for the radiation safety during the operation of the accelerator. In this paper, the general considerations for radiation shielding design of medical proton/heavy ion accelerator are briefly analyzed, and several common methods of shielding calculation are introduced with an example of calculation. The research in this paper has certain reference significance for the radiation shielding design of medical proton/heavy ion accelerator to be built in the future.

Key words: medical proton/heavy ion accelerator, shielding design, considerations, shielding calculation method
