Long-term health effects of internal exposure would depend on how strong the seeds or pellets were and how long they stayed in the body.įor more information on protecting yourself before or during a radiologic emergency, see CDC’s fact sheet titled “Frequently Asked Questions (FAQs) About a Radiation Emergency” at, and “Sheltering in Place During a Radiation Emergency,” at. Ir-192 seeds and pellets would be excreted in the feces. Internal exposure from Ir-192 could cause burns in the stomach and intestines if the high-energy industrial pellets are swallowed. Non-standard isotope - Non-standard isotope. Internal exposure could occur only if a person were to swallow one of the Ir-192 seeds or pellets. Molecular Formula192Ir Average mass191.963 Da Monoisotopic mass191.962601 Da ChemSpider ID59748. It involves the testing and grading of welds on pressurized piping, pressure vessels, high-capacity storage containers, pipelines, and certain structural welds. External exposure to Ir-192 can cause burns, acute radiation sickness, and even death. Iridium-192 (Ir-192) ATOMENERGOEXPORT Iridium-192 (Ir-192) Iridium-192 emits gamma rays of high energy, so sealed sources with Ir-192 can be successfully applied in gamma radiography. Ir-192 is a shiny, silvery-white, very dense metal that will not rust when exposed to natural elements.Įxposure to Ir-192 can increase the risk for cancer because of its high-energy gamma radiation. Industrial gauges hold pencil-like metal sticks of solid Ir-192 or small pencil-like tubes that contain pellets of Ir-192. Ir-192 used in medicine is in the form of tiny seeds, each about the size of a grain of rice. Ir-192 is a manmade radioactive element that is formed from nonradioactive iridium metal in a nuclear reactor. A high dose rate of this radioisotope can be used in. Ir-192 is used in industrial gauges that inspect welding seams and in medicine to treat certain cancers. Iridium-192 emits gamma rays and has a half-life of 74 days. Metallic Ir-192 will react with fluorine gas to form iridium fluoride (IV), IrF 6. Mode of decay: Beta particles and gamma radiation.Ĭhemical Properties: Dense metal.
