Bismuth half-life
WebDec 28, 2024 · The half-life of a radioactive isotope is the average amount of time it takes about one-half of the atoms in a sample of radioisotope to decay. Different radioisotopes decay at different rates and can have wildly differing half-lives; these half-lives can be as short as a few microseconds, such as in the case of polonium-214, and as long as a ... WebThe 7.2-h half life radiohalogen (211)At offers many potential advantages for targeted α-particle therapy; however, its use for this purpose is constrained by its limited availability. Astatine-211 can be produced in reasonable yield from natural bismuth targets via the (209)Bi (α,2n) (211)At nuclear reaction utilizing straightforward methods.
