本标准的范围是为四类报警电子辐射测量仪器制定最低性能标准和测试要求，这些仪器用于在应急响应人员暴露于光子辐射时通过报警来管理暴露。这些仪器能够快速、清晰地指示辐射暴露水平和/或暴露率，并提供易于识别的警报。警报既有声音也有视觉，并可区分暴露率和暴露。振动警报是可选的。应急响应人员包括消防和救援服务、执法和医疗服务。 其他可能的用户包括关键基础设施关键资源（CIKR），如重型设备、运输和公用事业人员。

The scope of this standard is to establish minimum performance criteria and test requirements for four categories of alarming electronic radiation measurement instruments used to manage exposure by alerting the emergency responders when they are exposed to photon radiation. The instruments provide rapid and clear indication of the level of radiation exposure and/or exposure rate and readily recognizable alarms. The alarms are both audible and visual, and distinguishable between exposure rate and exposure. Vibratory alarms are optional. Emergency responders include fire and rescue services, law enforcement, and medical services. Other possible users include Critical Infrastructure Key Resources (CIKR) such as heavy equipment, transportation, and utilities personnel.
