辐射防护仪器.检测放射性和核材料非法贩运用安装的辐射入口监测器

[中文适用范围]： 本文档定义了用于检测伽马辐射和中子辐射发射器的安装式监测器的性能要求。这些监测器通常称为辐射门式监测器或RPM。它们用于监测车辆、货物集装箱、人员或包裹，通常位于国家和国际边境口岸。它们也可用于任何需要此类监测的场所。本文档确立了通用、放射性、气候、机械、电气和电磁以及文件要求和相关测试方法。性能要求摘要见表6。IEC 62706中关于环境要求的参考性列表见表7。本文档不适用于IEC 62484涵盖的光谱分析门式监测器的性能。 [外文原描述]： IEC 62244:2019 defines the performance requirements of installed monitors used for the detection of gamma and neutron radiation emitters. These monitors are commonly known as radiation portal monitors or RPMs. They are used to monitor vehicles, cargo containers, people, or packages and are typically located at national and international border crossings. They may be used at any location where there is a need for this type of monitoring. This document establishes the general, radiological, climatic, mechanical, electric and electromagnetic and documentation requirements and associated test methods. This document does not apply to the performance of spectroscopy-based portal monitors covered in IEC 62484. This second edition cancels and replaces the first edition issued in 2006. This edition includes the following significant technical changes with respect to the previous edition: a) making the standard consistent with the new standards for detection of illicit trafficking of radioactive material (see the Introduction); b) creating unformed functionality test for all environmental, electromagnetic and mechanical tests and a requirement for the coefficient of variation of each nominal mean reading; c) reference to IEC 62706 for the environmental, electromagnetic and mechanical test conditions; d) adding information regarding climatic exposures.
