Abstract:
1. A transportation container inspection system comprising (a) a radiation scanner for scanning X-ray beams over a transportation container to be inspected, each of said beams having an energy level sufficient to penetrate said container, (b) at least one X-ray sensor record member having a surface located at a distance from said container and positioned to receive transmitted X-ray radiation from said container, said record member being capable of storing energy corresponding to said transmitted X-ray radiation and being responsive to stimulating radiation to emit light corresponding in intensity to said stored energy, (c) a detector for delivering stimulating radiation to said record member and detecting said light emitted by said record member, and (d) computer analysis equipment for comparing said intensity of said emitted radiation with known reference values to determine the likely composition of a material in said container.
