标准编号：IEC 62694:2022

中文名称：辐射防护仪器.用于检测放射性物质非法贩运的背包式辐射探测器（BRD）

英文名称：Radiation protection instrumentation - Backpack-type radiation detector (BRD) for the detection of illicit trafficking of radioactive material

发布日期：2022-11-29

标准范围

IEC 62694:2022适用于主要用于检测放射性材料非法贩运的背包式辐射探测器(BRD)。BRD是设计用于在使用过程中佩戴的便携式器械。BRD检测γ辐射，可能包括中子检测和识别发射γ射线的放射性核素的能力。本文件规定了与辐射测量相关的操作和测试要求以及使用时预期的电气、机械和环境条件。第二版取消并取代了2014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.使该标准与检测非法贩运放射性材料的新标准相一致；b.为所有环境、电磁和机械测试创建未成形功能测试，并要求每个标称平均读数的变异系数；c.修订放射性要求，包括简化放射性核素鉴定验收标准；d.环境、电磁和机械试验条件参考IEC 62706。

IEC 62694:2022 applies to backpack-type radiation detectors (BRDs) that are primarily used for the detection of illicit trafficking of radioactive material. BRDs are portable instruments designed to be worn during use. BRDs detect gamma radiation and may include neutron detection and the ability to identify gamma-ray emitting radionuclides.
This document establishes the operational and testing requirements associated with radiation measurements and the expected electrical, mechanical, and environmental conditions while in use.
This second edition cancels and replaces the first edition, published in 2014. 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;
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. revised radiological requirements including the simplification of radionuclide identification acceptance criteria;
d. reference to IEC 62706 for the environmental, electromagnetic and mechanical test conditions.
