IODINE-131 is obtained either from fission products of uranium-235 or, more conveniently, by neutron irradiation of tellurium in the form of metal or oxide. Naturally occurring tellurium consists of 18.7 per cent tellurium-126, 31.8 per cent tellurium-128, 34.5 per cent tellurium-130 and five other minor nuclides. Irradiation will give rise to three iodine isotopes by the concurrent nuclear reactions
