防辐射装置.放射性物质非法运输检测用人体辐射报警装置(PRDs

[中文适用范围]： 本文件适用于袖珍型、随身携带、用于检测和指示伽马辐射场的存在和一般强度的报警辐射检测仪器。还可以提供中子检测。个人辐射设备 (PRD) 会提醒用户存在明显高于测量的平均局部背景辐射水平的辐射源。它们并非旨在提供环境或个人剂量当量率的测量。本文件的目的是描述设计和功能标准以及用于评估用于检测放射性材料非法贩运（例如用于边境辐射监测）的 PRD 性能的测试方法。本文件不适用于 IEC 60846-1 或 IEC 61526 分别涵盖的环境或个人剂量当量率计。如果制造商声明 PRD 可用于辐射防护目的，则需要符合 IEC 60846-1 或 IEC 61526。 [外文原描述]： IEC 62401:2017 describes design and functional criteria along with testing methods for evaluating the performance of Personal Radiation Devices (PRDs) used for detection of illicit trafficking of radioactive material (e. g., for border radiation monitoring). This document applies to alarming radiation detection instruments that are pocket-sized, carried on the body and used to detect and indicate the presence and general magnitude of gamma radiation fields. Neutron detection may also be provided. This new 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) changing some basic requirements; c) creating a uniform functionality test for all environmental, electromagnetic and mechanical tests; d) reference to IEC 62706 for the environmental, electromagnetic and mechanical test conditions.
