Inc. Innovations SCIENTIFIC SIMULTANEOUS DETECTION OF EXPLOSIVES AND NUCLEAR MATERIALS USING MONO-ENERGETIC HIGH ENERGY GAMMA RAYS Scientific Innovations, Inc. Joseph Brondo President and CEO Brookhaven National Laboratory Lucian Wielopolski, P.I. Naval Surface Warfare Center March 2, 2005
Objectives • A full scale demonstration system for resonance technology for explosives and IED detection in transmission and standoff modes. • Demonstration of simultaneous detection of explosives and nuclear materials. SCIENTIFIC INNOVATIONS, INC. BROOKHAVEN NATIONAL LABORATORY
Physics –Radiation Interaction with Matter Gamma Resonance Technology, GRT is based on resonance interaction of gamma radiation with a specific level in a nucleus of an element of interest, e.g., N, O, Cl, and detection of the transmitted incident radiation or that induced by nuclear fluorescence. Photo-Fission Technology, PFT is based on nuclear absorption of energetic gamma rays that above threshold energy induce fission in fissile materials, e.g., U-235, Pu-239, Th-232, and subsequent detection of the emitted delayed neutrons. High-Z Detection Technology, HZT is based on attenuation of dual or triple high energy gamma beams and solving simultaneous transmission equations for resolving high- and low-z materials.

Simultaneous inspection for explosives and nuclear materials • Monoenergetic high energy gamma rays ~ 10 MeV • High throughput (1600 bags/hr, 24LD-3/hr/station) • Specific signature for explosives • Fully automated decision making • Single source can feed multiple inspection stations • Low false alarm rate (<5%) • No residual activation or site contamination • Elemental 3-D imaging capability Basic Characteristics SCIENTIFIC INNOVATIONS, INC. BROOKHAVEN NATIONAL LABORATORY
Public Safety • Accelerator produces low energy x-rays. • Target produces only gamma radiation, no neutrons. • Shielded highly collimated beam. • Dose to image N in human body 0.026 mrem. • Dose to stowaway will be considerable lower. • Gamma flux is two to three orders of magnitude • lower than for VACIS or CT systems.

Resonance cross section is given by the Breit-Wigner formula: abi (E-ER)2 + 2/4 where g is a statistical factor given by: abi = 2g 2J + 1 g = (2s + 1)(2i + 1) Gamma Resonance Technology, GRT SCIENTIFIC INNOVATIONS, INC. BROOKHAVEN NATIONAL LABORATORY

The ratio of the two identifies the explosive At 9.17 MeV gamma ray resonance attenuation is about four times higher than the non resonant radiation. SCIENTIFIC INNOVATIONS, INC.

Target Accelerator Protons Scattering Detectors Object Scattered Beam Transmitted Beam Transmission Detectors Gamma Resonance Technology, GRT A low energy proton beam hits a dedicated target and produces resonance gamma rays. These interact resonantly with N or Cl encountered in the explosive. Monitoring the transmitted and the scattered beams, with the transmission and scattering detectors, respectively, allows analysis and imaging of the elements of interest. SCIENTIFIC INNOVATIONS, INC.
