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.
A total of 511 PBq of iodine-131 was released into both the atmosphere and the ocean, 13.5 PBq of caesium-134 and 13.6 PBq of caesium-137. [62] In May 2012, TEPCO reported that at least 900 PBq had been released "into the atmosphere in March last year [2011] alone" [ 63 ] [ 64 ] up from previous estimates of 360–370 PBq total.
[1] [2] When the iodine atom is a radioactive isotope (iodine-125 or iodine-131), it is used as an adrenal cortex radiotracer in the diagnosis of patients suspected of having Cushing's syndrome, hyperaldosteronism, [3] pheochromocytoma, and adrenal remnants following total adrenalectomy. [1] [2]
The crew consisted of ten film students and done on a low budget. The project was filmed in Northern Ontario 's Parry Sound on super 16mm film, over the course of 15 days. Produced by The Dot Film Company Inc., it runs for 97 minutes and was recognized in the Montreal World Film Festival in 2009.
Iodine-131 (131 I) is the most common RNT worldwide and uses the simple compound sodium iodide with a radioactive isotope of iodine. The patient (human or animal) may ingest an oral solid or liquid amount or receive an intravenous injection of a solution of the compound. The iodide ion is selectively taken up by the thyroid gland.
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.
Of particular concern at the time was the radioactive isotope iodine-131, with a half-life of about eight days. Iodine taken up by the human body is preferentially incorporated in the thyroid . As a result, consumption of iodine-131 can give an increased chance of later suffering cancer of the thyroid .
Distribution areas for iodine pills in the Netherlands (2017). In the Netherlands, the central storage of iodine-pills is located in Zoetermeer, near The Hague. In 2017, the Dutch government distributed pills to hundreds of thousands of residents who lived within a certain distance of nuclear power plants and met some other criteria. [51] [52]
