Large Clearance Monitor
The Mirion RTM644-Smart Gamma Clearance Monitor is designed for measurements of large items like EPAL crates, 400 or 200 liters drums, palettes or big-bags with a measurement chamber size of 1870 liters.
The RTM644-Smart is the most advanced clearance monitor and key monitoring equipment for every major clearance campaign. It consists of a measurement chamber with motor-operated swing doors and automatic chain conveyor system. The measurement objects are weighed by integrated scales and checked for gamma radiation by 24 state-of-the-art plastic scintillation detectors with spectroscopic readout.
The RTM644-Smart shares the common, modern Lighthouse™ monitor software platform, with Windows 10 IoT operating system. This analysis software reports nuclide specific activity, brings lower measurement uncertainties, handles complex nuclide vectors, automatizes loading and simplifies maintenance.
It is based on the well-proven algorithm principles and improved leading nuclide correlation (LNC) technology as used in many Mirion RTM monitors. The state-of-the-art spectrometric detector read-out and the simulation-based object models, allow an unprecedented measurement accuracy. It provides with reliable efficiency correction for all nuclides in the fingerprint. The automatic verification and optimization of the declared nuclide vector can further reduce the measurement uncertainties.
The RTM644-Smart comes with advanced administrator and maintenance features: the realtime energy spectrum display provides with a radiological health check of detector array on a single glance. All calibration and routine efficiency checks are configurable and software guided. The comprehensive and intuitive monitor software comes with user configurable libraries for release limits, radiological fingerprints or editable standard objects like crates or waste drums.
To extend the functionality to application-specific objects or assess specific environmental conditions or nuclide vectors, validated Monte-Carlo-simulations are available as a complementary service. The self-contained results database facilitates customized report generation, decision tracing and recalculation.
