WebIodine-131 has a half-life of 8.06 days and decays by beta-particle emission to a stable 131 Xe. The principal mean beta energy (90%) is 192 keV. Several gamma rays are also … WebThe xenon-123 formed by either route then decays to iodine-123, and is trapped on the inner wall of the irradiation capsule under refrigeration, then eluted with sodium hydroxide in a halogen disproportionation reaction, similar to collection of iodine-125 after it is formed from xenon by neutron irradiation (see article on 125 I for more details).

Iodine-131, in higher doses than for thyrotoxicosis, is used for ablation of remnant thyroid tissue following a complete thyroidectomy to treat thyroid cancer. Administration of I-131 for ablation. Typical therapeutic doses of I-131 are between 2220 and 7400 megabecquerels (MBq). See more Iodine-131 ( I, I-131) is an important radioisotope of iodine discovered by Glenn Seaborg and John Livingood in 1938 at the University of California, Berkeley. It has a radioactive decay half-life of about eight days. It is … See more Most I production is from neutron irradiation of a natural tellurium target in a nuclear reactor. Irradiation of natural tellurium produces almost entirely I as the only radionuclide with a half-life longer than hours, since most lighter isotopes of tellurium become … See more Iodine-131 is used for unsealed source radiotherapy in nuclear medicine to treat several conditions. It can also be detected by gamma cameras for diagnostic imaging, however it is rarely administered for diagnostic purposes only, imaging will normally be done … See more • Isotopes of iodine • Iodine in biology See more I decays with a half-life of 8.02 days with beta minus and gamma emissions. This isotope of iodine has 78 neutrons in its nucleus, while the … See more Iodine in food is absorbed by the body and preferentially concentrated in the thyroid where it is needed for the functioning of that gland.
