GAMON-S
Category: Characterization > Monitors > Radiation Monitors
Reference # : Model No :
The GAMON-S is a gamma radiation spectroscopy system designed for outdoor and indoor online radiation monitoring, for early environmental warning and emergency response. It can operate in harsh weather conditions and is protected from rain and moisture. The GAMON-S can be deployed in a wide range of scenario, as in permanent ring monitoring as well as in moving monitoring stations thanks to GPS coordinate logging.
The GAMON-S spectrometer runs automatic isotope identification and isotope related dose rate evaluation. The real-time data processing and the defined isotope based alarm allow GAMON-S to detect the presence of artificial nuclides in a short time window and more effectively compared to traditional dose rate meters.
