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

[中文适用范围]： 本文档适用于主要用于检测放射性物质非法贩运的背包式辐射探测器（BRD）。BRD是便携式仪器，设计为在使用时佩戴。BRD检测伽马辐射，可能包括中子检测和识别伽马射线发射放射性核素的能力。 本文档建立了与辐射测量相关的操作和测试要求，以及使用时的预期电气、机械和环境条件。 本文档不适用于环境或个人剂量当量率计，这些分别涵盖在IEC 60846-1或IEC 61526中。 [外文原描述]： 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.
