EcoGamma-g monitor is an advanced, dual detector, environmental gamma radiation monitor designed to operate in the most extreme conditions with unsurpassed accuracy, range and stability.
The Mirion EcoGamma-g monitor is an advanced, dual detector, environmental gamma radiation monitor designed to operate in the most extreme conditions with unsurpassed accuracy, range and stability. Leveraging a long history of operating experience from the Mirion environmental monitoring family, the EcoGamma unit incorporates Mirion's unique "Time To Count", counting technique with its high and low range Geiger Mueller detectors in an assembly that provides excellent accuracy and linearity throughout its 1 μR/hr (10 nSv/hr) to 1000 R/hr (10 Sv/hr), H*10 compliant, 30 keV to 5.0 MeV operating range. The assembly is housed within a single IP67 rated weatherproof aluminum enclosure designed to provide stable, reliable performance in demanding operating environments.
The EcoGamma-g monitor logs all data including dose rates, detector status, count rates, alarms, faults, etc. to its internal memory at one minute intervals, for 180 days of continuous storage. The historical data is completely maintained by the device, assuring that data will continue to be captured and stored even if communication with clients has been lost. The client application supplied with the EcoGamma-g monitor includes capabilities for displaying and reporting historical and current data in various forms, including histogram and tabular. Historical and current data is also available for routine activities such as plotting of trends and enhanced performance monitoring.
Monitor performance and reliability are further assured through the EcoGamma system's rigorous self test functionality, that continuously evaluates detector and sensor performance, high voltage, communications and critical circuit operation. The EcoGamma-g monitor's serial number is burned-in at the time of manufacture. All measurements and log data are tagged with this data. This feature makes supporting the traceability of calibrations, testing, performance plotting, measurements and trending an automatic affair.
Each monitor comes complete with LED operating status indicator, Ethernet and USB connectors and is "Powered over Ethernet" (POE). The EcoGamma-g monitor can also accommodate a variety of external communication, power and hardware requirements. Its platform neutral software readily handshakes with common communication protocols, including line, RF, GSM, etc. EcoGamma monitors are designed to be easily networked. The monitor's threaded base accommodates a variety of mounting options and modular add-ons like back-up power.
EcoGamma systems contain an embedded temperature detector and logs its temperature data within the monitor's internal historical database. This data can supplement general environmental information at the monitor's location providing additional background concerning local conditions. Moreover, temperature data can assist with preventative maintenance and troubleshooting by providing early warning in the unlikely event that the broad temperature range of the detector has been exceeded.
The Total Integrated Radiation Dose (TID) of the monitor, as well as individual detector tube doses are also tracked by the EcoGamma system. With this data, failures may be anticipated based on the accumulated counts. TID information aids in proactive maintenance by providing users with an estimate of how much life is available on the detectors. Associating all of this data with each detector aids in retrospective performance analysis.
The design of the EcoGamma unit offers an unparalleled degree of positional integrity, consistency and repeatability of its calibration routine. Its assembly is designed with tight tolerances for repeatable positioning and its housing provides visible marking of detector centerpoints to assure that the detectors are always calibrated at the same location and orientation. Calibration and linearity check functions within the software allow adjustment of calibration test points and ranges in accordance with local regulatory requirements. Test points may be added or subtracted to better refine calibration without special software modifications or workarounds. Calibration data is loaded and retained by the device maintaining complete calibration history within the device.
