Iodine 131 and iodine 125 are emitter of
WebIodine-125 is a commonly used radionuclide with a half-life of 60 days, emitting gamma rays with a maximum energy of 0.035 MeV (Million Electron Volts). See chart below for the decay rate information for I-125. Concerns The major concern with using I-125 is radiation exposure in air over an unshielded vial. Web6 okt. 2024 · Radioactive iodine (I-131), an isotope of iodine that emits radiation, is used for medical purposes. When a small dose of I-131 is swallowed, it is absorbed into the bloodstream in the gastrointestinal (GI) tract. It is concentrated from the blood by the thyroid gland, where it begins destroying the gland’s cells.
