IEC 62401:2017（e）描述了用于检测放射性材料非法贩运（例如，用于边境辐射监测）的个人辐射设备（PRD）性能评估的设计和功能标准以及测试方法。本文件适用于袖珍、随身携带、用于探测和指示伽马辐射场的存在和一般大小的报警辐射探测仪器。还可以提供中子检测。 与上一版相比，此新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相一致（见导言）； b）？改变一些基本要求； c）？为所有环境、电磁和机械测试创建统一的功能测试； d）？参考IEC？62706用于环境、电磁和机械试验条件。

IEC 62401:2017(E) 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.
