IEC 62463:2024适用于设计用于使人员暴露于X？射线。特别地，该文件适用于身体暴露于X射线初级束的系统。通常将目前使用的系统分为三种类型:反向散射系统、传输系统和反向散射/传输组合系统。本文件的目的是从辐射防护的角度提供标准化的要求和测试方法，以确保X射线人员筛查系统的安全运行。特别是，该文件规定了与被检查人员、设备附近人员和操作员的辐射防护相关的要求。 第二版取消并取代了2010年出版的第一版。与上一版相比，此版本包括以下重大技术变更: a)标题修改； b)将主要剂量数量从环境剂量当量（H*（10））更新为ICRU报告95:2020中推荐的操作量； c)范围已从用于筛查人员的X射线系统更新为出于安全目的故意将人员暴露在X射线下的X射线系统，这澄清了d)被占用的车辆扫描仪是否在范围内的模糊性； d)用于对系统进行分类的方案从基于系统是否是反向散射、透射或组合的方案改变为基于剂量水平和管理控制的分类系统； e)更新了许多电气、环境、电磁和机械安全要求。

IEC 62463:2024 is applicable to security screening systems designed to expose persons to X？rays. In particular, the document applies to systems where the body is exposed to the primary beam of X-rays. It is common to divide currently used systems into three types: backscatter systems, transmission systems and combination backscatter/transmission systems. The purpose of this document is to provide standardized requirements and test methods to ensure the safe operation of X-ray personnel screening systems, from a radiation protection point of view. In particular, the document specifies requirements related to the radiation protection of the persons being screened, persons who are in the vicinity of the equipment and the operators.
This second edition cancels and replaces the first edition published in 2010. This edition includes the following significant technical changes with respect to the previous edition:
a) title modified;
b) the main dose quantity was updated from ambient dose equivalent (H*(10)) to the operational quantities recommended in ICRU Report 95:2020;
c) the scope has been updated from X-ray systems for screening persons to X-ray systems that deliberately expose persons to X-rays for security purposes, which clarifies the ambiguity of whether d) occupied vehicle scanners are within scope;
d) the scheme for classifying systems was changed from one based on whether the system is backscatter, transmission or a combination to a classification system based on the dose level and administrative controls;
e) numerous electrical, environmental, electromagnetic, and mechanical safety requirements were updated.
