Abstract
This disclosure describes methods for manufacturing a radioisotope of actinium from an irradiated source material that includes thorium. The method includes storing the source material in a vessel to allow at least some of the source material to decay into actinium. The containment vessel is then injected with supercritical carbon dioxide and a ligand to form a metal complex of actinium. The actinium complex is then removed from the vessel without substantially removing any of the thorium from the vessel.
