Iridium-192 (symbol 192Ir) is a radioactive isotope of iridium, with a half-life of 73.83 days.
[11] It decays by emitting beta (β) particles and gamma (γ) radiation.
About 96% of 192Ir decays occur via emission of β and γ radiation, leading to 192Pt.
[12] Iridium-192 is normally produced by neutron activation of natural-abundance iridium metal.
[14][15] There are seven principal energy packets produced during its disintegration process ranging from just over 0.2 to about 0.6 MeV.
