Overview

The GAMON-D is a gamma dose rate monitoring system series, designed for outdoor and indoor online radiation monitoring, for early environmental warning and emergency response.
The GAMON-D can operate in a wide range of scenarios, such as permanent ring monitoring and in-motion monitoring stations. It can be mounted on a tripod to be easily repositioned for typical security or emergency response applications while the GPS monitors the current location.
The GAMON-D embeds two energy compensated Geiger–Mueller (GM) detectors to provide a wide detection range for ambient equivalent dose rate H*(10). The high-volume GM is used for low dose rate measurement and can detect small changes in the natural background even in short acquisition cycles.
The control of the two detectors is performed by the internal electronics, which continuously monitors the count rate. Customized extended range dose rate can be provided on request, from 10 nSv/h to 10 Sv/h. It can operate in a wide temperature range from -40 to 60 °C and in adverse weather conditions as it is protected from rain and humidity. CAEN offers both the GAMON-D as a stand alone unit for easy integration or a more complete station system including mounting inox-steel structure with rain-sensor, back up batteries, electric cabinet, solar panel and mobile communications.
