This is a United States Patent document (US 9,666,317 B2) issued to American Ceramic Technology, Inc. on May 30, 2017. The patent, titled "Radiation Shield with Magnetic Properties," was invented by Richard V Culbertson, Randall M Ragan, and Joseph H Stupak, with the application filed on April 2, 2015 (Application No. 14/677,556).

The patent discloses a radiation attenuation shield, method, and system that incorporates a polymer, a radiation-attenuating material, and a magnetic material. Key technical features include the ability to disperse the magnetic material within the polymer to form an attenuation layer, and the option to position a magnetic material layer adjacent to or encasing the attenuation layer. The shield can be manufactured by combining components to create a mixture, inserting the mixture into a mold, and solidifying it into a final shape. The invention may be mechanically secured to a structure for radiation containment or secured using its magnetic properties. The patent contains 33 claims and includes 5 drawing sheets, with a primary examiner identified as Phillip A Johnston. References cited include multiple U.S. patents related to radiation shielding and material composition technologies.
