Iodine-131 (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. [3] It has a radioactive decay half-life of about eight days. It is associated with nuclear energy, medical diagnostic and treatment procedures, and natural gas production.
Product labeling for diagnostic 131 I iobenguane recommends giving potassium iodide one day before injection and continuing 5 to 7 days following. [ 19 ] 131 I iobenguane used for therapeutic purposes requires a different pre-medication duration, beginning 24–48 hours before iobenguane injection and continuing 10–15 days after injection.
The beta particles emitted by the radioisotope destroys the associated thyroid tissue with little damage to surrounding tissues (more than 2.0 mm from the tissues absorbing the iodine). Due to similar destruction, 131 I is the iodine radioisotope used in other water-soluble iodine-labeled radiopharmaceuticals (such as MIBG) used therapeutically ...
Because of the short half-life of 8 days only 400 locations were still positive. This map showed that iodine-131 spread northwest of the plant, just like caesium-137 as indicated on an earlier map. But I-131 was also found south of the plant at relatively high levels, even higher than those of caesium-137 in coastal areas south of the plant.
The patient swallows a radioisotope of iodine in the form of capsule or fluid, and the absorption (uptake) of this radiotracer by the thyroid is studied after 4–6 hours and after 24 hours with the aid of a scintillation counter. The dose is typically 0.15–0.37 MBq (4–10 μCi) of 131 I iodide, or 3.7–7.4 MBq (100–200 μCi) of 123 I ...

One protocol is to discontinue levothyroxine, then prescribe liothyronine while the T 4 levels are falling, and finally stop the liothyronine two weeks before the radioactive iodine treatment. [ 5 ] Liothyronine may also be used for myxedema coma because of its quicker onset of action when compared to levothyroxine. [ 6 ]
