Abstract
The isotopes of an element have the same number of protons in their atoms but different masses due to different numbers of neutrons. When the nuclei of these isotopes undergo spontaneous disintegration to produce Ü, Ý or Þ rays it was called radioisotopes. These radioisotopes can be produced either by the reactor or the cyclotron. Iodine is one of the most common halogens located in group VII in the periodic table. There are 37 known isotopes of iodine (I) from 108I to 144I, but only one, 127I, is stable. Iodine is thus a monoisotopic element. Twelve radioisotopes from the rest radioisotopes of iodine are produced by fission and their half-lives ranging from 1.5 seconds (139I) to 16 million years (129I). Among these thirty seven radioactive iodine isotopes, four are of special interest, namely 123I, 124I, 125I and 131I
