Iridium-192 (symbol Ir) is a radioactive isotope of iridium, with a half-life of 73.83 days. It decays by emitting beta (β) particles and gamma (γ) radiation. About 96% of Ir decays occur via emission of β and γ radiation, leading to Pt. Some of the β particles are captured by other Ir nuclei, which are then converted to Os. Electron capture is responsible for the remaining 4% of Ir decays. Iridium-192 is normally produced by neutron activation of natural-abundance iridium metal. csl advanceWeb19 mei 2024 · May 19, 2024.
