  • Thin californium-containing radioactive source wires
    Patent number: 8088056
    Abstract: A cermet wire includes at least 1% californium-252 and is characterized by a diameter of no more than 0.0225 inch.
    Type: Grant
    Filed: April 24, 2006
    Date of Patent: January 3, 2012
    Assignee: UT-Battelle, LLC
    Inventors: Ian G Gross, Larry A Pierce
  • Method for fabricating thin californium-containing radioactive source wires
    Patent number: 7093476
    Abstract: A method for reducing the cross-sectional diameter of a radioactive californium-containing cermet wire while simultaneously improving the wire diameter to a more nearly circular cross section. A collet fixture is used to reduce the wire diameter by controlled pressurization pulses while simultaneously improving the wire cross-sectional diameter. The method is especially suitable for use in hot cells for the production of optimized cermet brachytherapy sources that contain large amounts of radioactive californium-252.

  • Cable attachment for a radioactive brachytherapy source capsule
    Patent number: 7077800
    Abstract: In cancer brachytherapy treatment, a small californium-252 neutron source capsule is attached to a guide cable using a modified crimping technique. The guide cable has a solid cylindrical end, and the attachment employs circumferential grooves micromachined in the solid cable end. The attachment was designed and tested, and hardware fabricated for use inside a radioactive hot cell. A welding step typically required in other cable attachments is avoided.
