Mode of decay: Beta particles and gamma radiation.
Chemical Properties: Dense metal. Metallic Ir-192 will react with fluorine gas to form iridium fluoride (IV), IrF 6.
What is it used for?
Ir-192 is used in industrial gauges that inspect welding seams and in medicine to treat certain cancers.
Where does it come from?
Ir-192 is a manmade radioactive element that is formed from non radioactive iridium metal in a nuclear reactor.
What form is it in?
Ir-192 used in medicine is in the form of tiny seeds, each about the size of a grain of rice. Industrial gauges hold pencil-like metal sticks of solid Ir-192 or small pencil-like tubes that contain pellets of Ir-192.
