辐射防护仪器.用于检测放射性材料非法贩运的基于光谱的报警个人辐射探测器（SPRD

[中文适用范围]： 本文件适用于基于光谱学的个人辐射探测器（SPRD）。SPRD检测和识别伽马辐射，并可能检测中子辐射。SPRD可以佩戴在腰带或口袋中，以提醒佩戴者存在辐射源。SPRD提供类似于个人辐射设备（PRD）的搜索功能，并具有识别辐射源的能力。它们可以区分由自然发生的放射性材料（NORM）或医用放射性核素引起的警报与工业来源或特殊核材料（SNM）引起的警报。 本文件建立了性能要求，并规定了通用特性、通用测试条件、放射学、气候、机械和电磁特性。 本文件还提供了用于确定SPRD是否符合所述要求的测试方法。 本文件不适用于IEC 61526和IEC 60846-1所涵盖的辐射防护仪器的性能。SPRD不用于准确测量个人（Hp（10））或环境（H*（10））剂量当量（率）。 [外文原描述]： IEC 62618:2022 applies to Spectroscopy-based alarming Personal Radiation Detectors (SPRD). SPRDs detect and identify gamma radiation and may detect neutron radiation. SPRDs can be worn on a belt or in a pocket to alert the wearer of the presence of a radiation source. SPRDs provide search, similar to that of a Personal Radiation Device (PRD), and identification capability to identify radiation sources. They can discriminate between alarms caused by Naturally Occurring Radioactive Materials (NORM) or medical radionuclides and alarms from industrial sources or Special Nuclear Material (SNM). This document establishes performance requirements and specifies general characteristics, general test conditions, radiological, climatic, mechanical, and electromagnetic characteristics. This document also provides test methods that are used to determine if an SPRD meets the stated requirements. This second edition cancels and replaces the first edition published in 2013. 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.
