HiEnergy Technologies' CarBomb Finder Model 3C4 detects bombs in closed car trunk in 11 seconds and estimates its weight non-invasively, in real time, automatically, and without human intervention. The van-borne CarBomb Finder decodes quantitative empirical chemical formulas of any selected substance in 30 seconds. Controlling the "Vertex" (head of the Car Bomb Finder from within the van from a console, the device inspects the car from three sides -- above, underneath and from the side. A metal/water compliant shielding protects the operator from radiation.
