WebIodine-123 is produced in a cyclotron by bombardment of enriched xenon-124 by the (p,2n) reaction via the shorter lived caesium-123 and xenon-123. The energy of the γ-ray emission (159 keV) is close to the ideal for imaging using gamma cameras. Several different iodination methods are employed to synthesise radiolabelled iodine-123 compounds.

WebIodine 131 thus became one of the earliest radioactive tracers. How can different isotopes of an element be produced? How can isotopes be produced--especially radioisotopes, which can serve many useful purposes? There are two basic methods: separation and synthesis. Some isotopes occur in nature. WebRadioactive I I-131 (also named Radioiodine I-131) therapy is a central medicine treatment. Doctors use i to treat an overly thyroid, a require labeled hyperthyroidism . Hyperthyroidism can be caused by Graves' disease, to which the entire thyroid gland the overactive, or by nodules within the gland which are locally highly in producing too much thyroid hormone.
