本标准适用于利用x射线或伽马辐射的安检系统，用于检查不在车辆、容器或外壳内的人员。具体而言，本标准适用于用于检测被暴露个体身上或体内携带物体的系统。 以下类型的系统包括在本标准的范围内: ？指定为固定、入口、可重新定位、可运输、移动或机架的系统。 ？采用初级辐射（传输系统）或散射辐射检测的系统 （后向散射系统）或两者的组合。 主要是成像，但也可能具有互补功能的系统，如材料 识别，或自动主动或被动威胁警报。本标准不涉及如何 测试这些互补特性。

This standard applies to security screening systems that utilize x-ray or gamma radiation and are used to inspect people who are not inside vehicles, containers, or enclosures. Specifically, this standard applies to systems used to detect objects carried on or within the body of the individual being exposed. The following types of systems are included in the scope of this standard: ⎯ Systems designated as fixed, portal, re-locatable, transportable, mobile, or gantry. ⎯ Systems employing detection of primary radiation (transmission systems), or scatter radiation (backscatter systems), or a combination of both. ⎯ Systems that are primarily imaging but that also may have complementary features such as material discrimination, or automatic active or passive threat alerts. This standard will not address how to test these complementary features.
