  • Method for large scale production of cesium-131 with low cesium-132 content
    Publication number: 20120142993
    Abstract: The present invention provides a method for large scale production of cesium-131 (Cs-131) with low cesium-132 (Cs-132) content, where the Cs-131 is produced via barium-131 (Ba-131) decay. Uses of the Cs-131 produced by the method include cancer research and treatment, such as for use in brachytherapy. Cesium-131 is particularly useful in the treatment of faster growing tumors.
    Type: Application

  • Brachytherapy implant seeds
    Patent number: 7410458
    Abstract: This invention includes methods of fabricating brachytherapy implant seeds, methods of fabricating brachytherapy implant seed cores, and brachytherapy implant seeds independent of method of fabrication. In one implementation, a brachytherapy implant seed includes a sealed inorganic metallic cylinder having a radioactive core received therein. The radioactive core includes an inorganic amorphous silicate glass tube having an exterior surface extending axially along the tube. An inorganic crystalline ceramic coating is received on at least a portion of the inorganic amorphous glass tube exterior surface. The coating includes a therapeutic dose of radioactive material. A radiographic marker is received within the sealed inorganic metallic cylinder. Other aspects and implementations are contemplated.
