标准范围

IEC 62618:2022适用于基于光谱的报警个人辐射探测器（SPRD）。SPRDs检测和识别伽马辐射，并可能检测中子辐射。SPRD可以佩戴在腰带上或口袋中，以提醒佩戴者辐射源的存在。SPRD提供类似于个人辐射设备(PRD)的搜索和识别能力以识别辐射源。它们可以区分由天然放射性物质（NORM）或医用放射性核素引起的警报和由工业源或特殊核材料（SNM）引起的警报。本文件建立了性能要求，并规定了一般特性、一般试验条件、辐射、气候、机械和电磁特性。本文件还提供了用于确定SPRD是否符合规定要求的测试方法。这第二版取消并取代了2013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（见导言）；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.环境、电磁和机械试验条件参考IEC 62706；d.添加有关气候暴露的信息。

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);
