EDS-GRT Objectives A Joint Program by Scientific Innovations, Inc. Brookhaven National Laboratory Rapid deployment of resonance technology for detection and imaging of concealed explosives, chemical warfare agents, and dirty and nuclear bombs in shipping containers
EDS-GRT: System Configuration An accelerator is used to produce protons at a specific energy such that unique resonant gamma rays are generated from impingement on a specific target. The emitted gamma rays pass through a volume of interest and interact resonantly with specific elements of interest so that images of the elemental density are developed from the variation in gamma detection counts. Fluorescence or scattered gammas resonant with the element are also detected simultaneously. Non resonant gamma rays are used to image total density. Multiple Patents are Held by SII
EDS-GRT: Capabilities • The Gamma Resonance method provides combined capability of absorption and florescence • Simultaneous detection and imaging of multiple elements for identification of contraband and total density for imaging of contents • 3-D tomographic, multiple projection and single sided configurations for specific applications • High penetration • High resolution

EDS-GRT Applications • Current EDS systems are incapable of interrogating • large marine shipping cargo containers with any • degree of elemental specificity. • EDS systems based on neutrons although providing • elemental specificity are highly controversial and • unsuitable for interrogating large marine shipping • cargo containers. • There is a need for new technology to interrogate • large marine shipping and air cargo containers. GRT Is Proposed To Provide This New Technology
