FAST NEUTRON RESONANCE RADIOGRAPHY FOR ELEMENTAL MAPPING

摘要

Methods and apparatus involving neutron resonance radiography are used to map the elemental composition of an object. Sets of neutrons having energies within particular energy bands are directed through an object to be imaged. The attenuation of the neutrons passed through the object is detected, and that data can be used to detect explosives, weapons, drugs and other contraband.
