Patent number: 12614645Abstract: A method of separating actinium and/or radium from proton-irradiated thorium metal. The thorium metal is irradiated to produce isotopes including thorium, actinium and/or radium. The resultant product is dissolved in solution and a selective precipitant is used to precipitate a bulk portion of the thorium. The precipitated thorium can be recovered. Chromatography is carried out on the remaining solution to remove residual thorium and to separate the actinium from the radium.Type: GrantFiled: August 28, 2023Date of Patent: April 28, 2026Assignees: THE UNIVERSITY OF BRITISH COLUMBIA, TRIUMF INC.Inventors: Andrew Kyle Henderson Robertson, Hua Yang, Stefan Zeisler, Paul Schaffer
