  • X-ray backscatter imaging of nuclear materials
    Patent number: 8848871
    Abstract: The energy of an X-ray beam and critical depth are selected to detect structural discontinuities in a material having an atomic number Z of 57 or greater. The critical depth is selected by adjusting the geometry of a collimator that blocks backscattered radiation so that backscattered X-ray originating from a depth less than the critical depth is not detected. Structures of Lanthanides and Actinides, including nuclear fuel rod materials, can be inspected for structural discontinuities such as gaps, cracks, and chipping employing the backscattered X-ray.
    Type: Grant
    Filed: November 3, 2011
    Date of Patent: September 30, 2014
    Assignee: UT-Battelle, LLC
