Description
The GALILEO Series Vehicle Radiation Portal Monitor is a radiation portal monitor developed for the automatic detection of gamma-emitting radionuclide-sourced radioactive contamination in the loads of vehicles such as trucks, lorries, and train wagons.
GALILEO screens vehicle loads for radiological aspects during their passage through the portal structure. The system assists in monitoring vehicle loads for radiation at scrap metal yards, recycling facilities, ports, logistics centers, customs points, nuclear facilities, and weighing stations.
The standard 2UV configuration consists of 2 large plastic scintillator detectors positioned on both sides of the passage path. For higher sensitivity or different vehicle geometries, a 4-detector 4UV configuration and special placement options can also be utilized.
Each detector is configured with a high-efficiency plastic scintillator facing the passage path, a PMT, high voltage, and signal processing electronics. The detectors are appropriately shielded to reduce the environmental background effect.
Vehicle passage is detected by transit sensors, and the vehicle’s speed is calculated. Count rates from the detectors are continuously compared with predefined alarm thresholds. In case of threshold exceedance, the system alerts the operator audibly and visually.
GALILEO software dynamically evaluates the environmental background and assists in reducing the risk of false alarms by considering the shielding effect caused by the vehicle load. Measurement results can be archived, generated as a PDF report, and automatically sent to defined email addresses.
