标准范围

IEC 62244:2019定义了用于检测伽马和中子辐射发射器的已安装监测器的性能要求。这些监测器通常被称为辐射门户监测器或RPM。它们用于监控车辆、货物集装箱、人员或包裹，通常位于国家和国际边境口岸。它们可以用于需要这种类型监控的任何位置。本文件规定了一般、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。本文件不适用于IEC 62484中涵盖的基于光谱的门户监测器的性能。第二版取消并取代了2006年发布的第一版。与上一版相比，此版本包括以下重大技术变更:a)使该标准与检测非法贩运放射性材料的新标准保持一致（见导言）；b)创建用于所有环境、电磁和机械测试的未成形功能测试以及对每个标称平均读数的变异系数的要求；c)环境、电磁和机械试验条件参考IEC 62706；d)增加有关气候暴露的信息。

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.
