| 中文摘要: |
| 国际辐射单位与测量委员会（ICRU）第95号报告提出了一套用于外照射辐射防护的新实用量。该实用量的设计是为了克服现有实用量在概念和技术上的缺点，实现对防护量更佳的估算。本文介绍了外照射实用量的发展过程、定义的变化、计算模体的变化和适用范围的变化，从而全面了解实用量变化的意义，供相关专业人员参考。 |
| 英文摘要: |
| A set of new operational quantities for external radiation protection was proposed in ICRU Report 95. The new operational quantities were designed to overcome the conceptual and technical shortcomings of the existing operational quantities, and to achieve a better estimation of the protection quantities. This paper introduces the development of operational quantities, and the changes in their definitions, calculation phantoms and the application scopes, so as to fully understand the significance of the changes in the new operational quantities, which can be used as a reference for the relevant professionals. |
