Ir 192 brachytherapy
WebIridium-192 (symbol 192 Ir) is a radioactive isotope of iridium, with a half-life of 73.83 days. [6] It decays by emitting beta (β) particles and gamma (γ) radiation. About 96% of 192 Ir decays occur via emission of β and γ radiation, leading to 192 Pt. WebIridium 192 (192 Ir), the most common HDR brachytherapy source, is high energy and requires a shielded vault for treatment. Logistically, this necessitates that interstitial implant procedures be performed in a shielded operating room and, if not available, that the interstitial implant will be left in the patient while he is moved for ...
