IEEE N42.49A-2011

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.
