Overview
ABSTRACT
The Associated Particle Technique (APT) is a fast neutron interrogation method allowing elemental characterization of bulk materials in 3D. It can be used as a second-level inspection complementary to X-ray imaging, which is used as first level inspection to detect a suspicious item in luggage or a container, to confirm and identify the nature of a threat. APT can thus detect explosives, illicit drugs, chemical agents and nuclear materials at different points in the security chain (public areas, seaports, borders, etc.).
