Radiation Portal Monitor For Vehicles
The GALILEO radiation portal monitor is designed to automatically scan the load of vehicles (trucks or rail wagons on weighting stations) passing through its structure, and to detect any radioactive contamination due to the presence of gamma emitting radionuclide.
The standard 2UV configuration is composed of 2 large plastic scintillator detectors, an electronic desktop rack and a PC control console.
A 4UV configuration is also available, employing 4 scintillators, as well as other customisable layouts.
>The count rates acquired by the detectors are continuously compared to the pre-set alarm thresholds; if a threshold is exceeded, the system immediately gives a warning to the operator through acoustic and luminous indications.
The detectors are installed in a portal configuration: two mechanical structures are installed one at each side of the passageway. The number of detectors can be adapted to the expected vehicle type or measurement geometry. Each detector is composed of a high-efficiency plastic scintillator facing the passageway, coupled with a PMT and the electronics for HV and signal processing. The detectors are properly shielded to lower the environmental background contribution.
A set of transit sensors detects the vehicle’s transit and calculates its speed.
