Description

The RTM662-300 is an advanced clearance monitor for large objects. It consists of a measurement chamber with a manually operated swing door. The objects are detected and weighed by integrated scales and checked for gamma radiation by 6 state-of-the-art plastic scintillation detectors with spectroscopic read-out.

The RTM662-300 is based on an advanced software platform with Windows 10 IoT operating system. This analysis software reports nuclide specific activity, brings lower measurement uncertainties, handles complex nuclide vectors and simplifies maintenance.

It is based on the well-proven algorithm principles and improved leading nuclide correlation method (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 RTM662-300 comes with advanced administrator and maintenance features: the real-time energy spectrum display provides with a radiological health check of detector array on a single glance. All calibration and routine efficiency checks are user-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 personalized report generation, decision tracing, recalculation and interfacing to waste management systems.
