本标准规定了国土安全应用中使用的基于背包的辐射探测系统（BRDs）的基本性能要求。BRD包括一个可装在背包、背心或肩包中的穿戴式检测组件，以及一个有线或无线用户界面/显示器。BRD应检测伽马辐射，可能包括中子检测和/或伽马射线放射性核素的识别。

This standard specifies the basic performance requirements for backpack-based radiation-detection systems (BRDs) used in homeland security applications. BRDs consist of a body worn detection assembly that may be carried in a backpack, vest, or shoulder bag, and a wired or wireless user interface/display. BRDs shall detect gamma radiation and may include neutron detection and/or the identification of gamma-ray emitting radionuclides.
