IEC 62533:2010适用于用于检测和定位放射性光子发射材料的手持仪器。这些仪器高度敏感，这意味着它们被设计用于检测通常光子背景范围内的微小变化，这些变化主要是由非法贩运或放射性物质的无意移动引起的。本标准的目的是制定性能要求，包括物理特性、一般试验条件、辐射特性、电气安全和环境条件。本标准提供了可接受的测试方法示例，以确定仪器是否符合本标准的要求。测试结果为用户提供了有关辐射探测仪器可靠探测光子源的能力的信息。

IEC 62533:2010 applies to hand-held instruments used for the detection and localization of radioactive photon emitting materials. These instruments are highly sensitive meaning that they are designed to detect slight variations in the range of usual photon background caused mainly by illicit trafficking or inadvertent movement of radioactive material. The object of this standard is to establish performance requirements including physical characteristics, general test conditions, radiation characteristics, electrical safety, and environmental conditions. This standard provides examples of acceptable test methods to determine if an instrument meets the requirements of this standard. The results of tests performed provide information to users on the capability of radiation detection instruments for reliably detecting photon sources.
