DEFINITION

Classification: 75/393

Utilizing Radioactive material, producing or treating Radioactive metal:

(under subclass 392) Process in which a Radioactive material is used to produce or to treat a free metal, in which a Radioactive metal (i.e., Technetium (Tc), Promethium (Pm), Polonium (Po), Francium (Fr), Radium (Ra), Actinium (Ac), Thorium (Th), Protactinium (Pa), Uranium (U), Neptunium (Np), Plutonium (Pu), Americium (Am), Curium (Cm), Berkelium (Bk), Californium (Cf), Einsteinium (Es), Fermium (Fm), Mendelevium (Md), Nobelium (No), Lawrencium (Lr), Unnilquadium (Unq), Unnilpentium (Unp), Unnilhexium (Unh)) is produced, or in which a metal that contains a Radioactive metal is treated.
