A High Level Gamma Alarm for Criticality Monitoring
- Du Pont de Nemours (E.I.) and Co., Aiken, SC (United States). Savannah River Lab.
A monitor was developed that detects the gamma radiation from a nuclear accident and gives visible and audible alarms when the radiation exceeds a predetermined level. The instrument also gives a failure alarm when certain common internal malfunctions occur. Auxiliary alarm contacts are available for use with external alarm systems. The instrument is battery powered and, consequently, is unaffected by short-term power outages. A charger maintains the alarm battery at full power.
