标准摘要
[中文适用范围]： 本文件适用于质子能量范围为70兆电子伏至250兆电子伏的医用质子加速器的辐射屏蔽设计和评估工作，包括束流传输系统和喷嘴组件等子系统。本文给出的辐射防护建议涵盖了法规、屏蔽设计目标和其他设计标准、制造商、辐射防护官员或合格专家、医学物理师、许可证持有者及其相互作用的角色、质子加速器周围的辐射源和辐射、加速器及其子系统的屏蔽（包括屏蔽材料和传输值、各种房间配置的计算、管道对辐射防护的影响）以及辐射测量等方面。本文不涵盖FLASH质子治疗。 [外文原描述]： This document is applicable to the radiation shielding design and evaluation work for medical proton accelerators of proton energies ranging from 70 MeV to 250 MeV, with subsystems such as beam transport system and nozzle components. The radiation protection recommendations given in this document cover the aspects relating to regulations, shielding design goals and other design criteria, role of the manufacturers, of the radiation protection officer or qualified expert, the medical physicist, the licensee and interactions between them, sources and radiations around a proton accelerator, shielding for accelerators and its subsystems (including shielding materials and transmission values, calculations for various room configurations, duct impact on radiation protection) and the radiological measurements. FLASH proton therapy is not covered by this document. NOTE 1 Annex A provides a list of the most used Monte-Carlo codes for shielding calculation. NOTE 2 Annex B provides the analytical methods and the corresponding necessary data for shielding calculation. NOTE 3 Annex C provides a set of examples on shielding calculation of barriers, maze and skyshine problems. NOTE 4 Annex D provides radiation shielding consideration on special topics.
