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 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.
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.

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.
An average alpha particle released by astatine-211 can travel up to 70 μm through surrounding tissues; an average-energy beta particle emitted by iodine-131 can travel nearly 30 times as far, to about 2 mm. [126] The short half-life and limited penetrating power of alpha radiation through tissues offers advantages in situations where the ...
Iodine-131 (usually as iodide) is a component of nuclear fallout, and is particularly dangerous owing to the thyroid gland's propensity to concentrate ingested iodine and retain it for periods longer than this isotope's radiological half-life of eight days. For this reason, people at risk of exposure to environmental radioactive iodine (iodine ...
Tositumomab is a murine monoclonal antibody which targets the CD20 antigen produced in mammalian cell. [1] It was combined with iodine-131 to produce a radiopharmaceutical for unsealed source radiotherapy, Iodine-131 Tositumomab (branded as Bexxar), for the treatment of non-Hodgkins lymphoma. [1]
