Overview
Used for the
rapid non-intrusive inspection of 10, 20, 40ft containers or cargo
trucks and reefers, it can also be used for tankers, small trucks,
minibuses and private cars; false walls, hidden compartments and
configuration changes will quickly be identified.
A. It is a
gantry design configured in a fixed inspection tunnel for minimum
size and optimized radiation safety, 10m wide and 32m long. All of
the mechanical structure which forms the basis of the gantry is
mounted above ground; the ground level is free of rails trenches and
able ducts.

B. Overall the design is simple in structure. It has a single
radiation source incorporating a patented two window collimator and
two detector arrays, one normal to the target vehicle and one offset
by 30O, detector A and detector B respectively. The source and
detectors are moved synchronously by overhead gantry drive while
passing over the vehicle to be screened. The target vehicle remains
stationary for the duration of the scan once it has entered the
screening tunnel. Two independent images are produced during a scan,
each providing a slightly different view of the inspected
cargo.
