WebPurpose: Thorium-226 (half-life 30.6 m) is a radionuclide of interest for use in targeted alpha therapy applications. Due to its short half-life, 226 Th must be provided through a radionuclide generator system from its parent 230 U (20.8 d). Furthermore, as the half-life of 226 Th is very short, it should be provided in a form that is directly amenable to use in … All but two elements up to bismuth (element 83) have an isotope that is practically stable for all purposes ("classically stable"), with the exceptions being technetium and promethium (elements 43 and 61). All elements from polonium (element 84) onward are measurably radioactive. Th is one of the two nuclides beyond bismuth (the other being U) that have half-lives measured in billions of …
