Device for detecting illegal hiding in cargo

摘要

The device consists of a neutron generator (1) below which a collimator (5) is placed to form a vertical bundle of neutrons penetrating through the scanned heavy load layer (6) from a distance detector system (8) located above the carriage for measuring the gauge thickness a load layer (11) (6), especially loaded iron ore, further above the wagon is a moisture measurement device (10) in the load (6) and a plurality of detectors (7) for detecting the underneath the rail-level wagon neutrons and gamma irradiation penetrating the scanned load (6), wherein a change in the neutron and gamma radiation energy spectrum is recorded on the radiographic image to indicate possible shelter (9) of cigarette packages.
