Kegunaan isotop iridium
- Metallic 192Ir (with a half-life of 74 days) is used as a radiation source in gamma cameras for non-destructive testing of products for manufacturing flaws, such as aircraft parts, boilers, and pipeline welds (Fig. IUPAC.77.1).
- Metallic 192Ir is used in brachytherapy,,,. 191mIr (with a half-life of 5 s) is used for blood flow imaging (angiography), especially in pediatric populations,. The m in the superscript 191mIr indicates a metastable state of the isotope.
- Iridium consists of two stable isotopes (191Ir and 193Ir) from which the radioactive isotopes 192Ir and 195mPt (with a half-life of 4 days) can be produced. Both are used in nuclear medicine. The m in the superscript 195mPt indicates a metastable state of the isotope.
