WebApr 13, 2024 · But even with isotopes from different elements, theranostics can work effectively as long as they can be attached to the same vector. The Promise Of Lutetium-177 And Actinium-225. According to Van den Berghe, two medical isotopes that are expected to grow in significance are lutetium-177 (Lu-177) and actinium-225 (Ac-225). The radioactive decay of Pt to Os has a half-life of 6.5(3)×10 years (which is longer than the age of the universe, so it is essentially stable). However, in-situ Os / Os and Os / Os of modern plume related magmas show simultaneous enrichment which implies a source that is supra-chondritic in Pt/Os and Re/Os. Since both parental isotopes have extremely long half-lives, the Os-isotope rich reservoir must be very old to allow enough time for the daughter isotopes to form. These observ…
