GEM-5 Gamma Exit Monitor


GEM-5 Gamma Exit Monitor


CANBERRA's highly sensitive GEM-5 gamma exit monitor provides power plants and nuclear facilities the very latest gamma detection capability to monitor pedestrians leaving areas of potential radioactive contamination. Operation of the monitor is straightforward and reliability is assured with both audible and visual aids to support monitoring activities. The easy to see color LCD screen provides visual cues and readily displays contaminated areas. Additionally, users are guided through the monitor with a voice annunciator, which provides clear voice prompts necessary for dependable unassisted operation during normal conditions. With CANBERRA WebRemote™ software, easy-to-use touch screen graphical user interface for industrial PC-based operation results in improved health physics programs, better tracking of contamination and faster, more thorough personnel throughput at boundary points.

Access to the installed computer is through a single convenient panel on the front of the monitor. The computer includes built in USB and LAN ports, and is located inside a lockable door.

The GEM-5 is rugged, reliable and extremely easy to use.
