Abstract
Apparatus for inspecting baggage moved relative to an x-ray beam. The apparatus causes a beam of x-rays to pass through a reference in the course of exposure and detects the presence of the reference material contained within the baggage by matching the effective atomic number of the materials within the bag, with the atomic number of the reference.
