Explosive Detection Systems Using Gamma Resonance Technology

Gamma Resonance Technology provides the combined capability of absorption and fluorescence in the simultaneous detection and imaging of multiple elements for identification of contraband and total density for imaging of contents. This method of scanning is unique in its ability to provide imaging by element coincident with total density imaging. In addition it includes both high resolution and high penetration without induced radioactivity as is encountered with neutron techniques. The scanning beam dynamics and geometry allow for system configurations that provide 3‐D tomographic, multiple projection, single sided imaging and standoff identification. This technique has been demonstrated for high explosives including thin sheet containing nitrogen and present system design is to include nitrogen, oxygen, chlorine and other elements of interest.
