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.
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 ...
Sources cite 5,500 to 12,000 curies (200 to 440 TBq) of iodine-131 released, [1] [2] [3] and an even greater amount of xenon-133. The radiation was distributed over populated areas and caused the cessation of intentional radioactive releases at Hanford until 1962, when more experiments commenced. [3]

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.
An elimination diet may be appropriate if you suspect that certain foods are causing adverse reactions or symptoms such as bloating, digestive issues, skin problems, headaches, or fatigue. It can ...
Elimination diets aren’t foolproof, though, the Mayo Clinic says. Yes, they’ll help you understand what about your diet is causing stomach problems. But they alone can’t pinpoint whether the ...
Levels of radioactive iodine-131 in seawater near the facility are found to be 7.5 million times the legal limit. [117] TEPCO drills a hole into the pit near reactor 2, from which highly radioactive water is leaking, and injects water glass ( sodium silicate ) into the pit to prevent further leaking.
