  • Detecting special nuclear materials in suspect containers using high-energy gamma rays emitted by fission products
    Patent number: 7529332
    Abstract: A method and a system for detecting the presence of special nuclear materials in a suspect container. The system and its method include irradiating the suspect container with a beam of neutrons, so as to induce a thermal fission in a portion of the special nuclear materials, detecting the gamma rays that are emitted from the fission products formed by the thermal fission, to produce a detector signal, comparing the detector signal with a threshold value to form a comparison, and detecting the presence of the special nuclear materials using the comparison.
    Type: Grant
    Filed: September 7, 2007
    Date of Patent: May 5, 2009
    Assignee: The Regents of the University of California
    Inventors: Eric B. Norman, Stanley G. Prussin

  • Neutron interrogation system using high gamma ray signature to detect contraband special nuclear materials in cargo
    Patent number: 7359480
    Abstract: A system for inspecting cargo for the presence of special nuclear material. The cargo is irradiated with neutrons. The neutrons produce fission products in the special nuclear material which generate gamma rays. The gamma rays are detecting indicating the presence of the special nuclear material.
