GALILEO Series

Radiation portal monitor for vehicles with large plastic scintillators

Radiation portal monitor that automatically scans the load of trucks and rail wagons, for example on weighing stations, for gamma-emitting radionuclides. Plastic scintillators on both sides of the passage are continuously compared with the alarm thresholds and a dynamic algorithm accounts for the vehicle’s own shielding; on alarm the operator gets acoustic and luminous signals and the report can be e-mailed as a PDF.

Detector type: Plastic scintillators, 2–4 units (custom on request), 25 L and 5000 cm² each, 5 cm deep2
Energy range: 35 keV–2 MeV2
Weight: 171 kg per detector lodging2
