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.
On March 24, 2011, Japanese officials announced that "radioactive iodine-131 exceeding safety limits for infants had been detected at 18 water-purification plants in Tokyo and five other prefectures". Officials said also that the fallout from the Dai-ichi plant is "hindering search efforts for victims from the March 11 earthquake and tsunami". [70]
The radiation effects from the Fukushima Daiichi nuclear disaster are the observed and predicted effects as a result of the release of radioactive isotopes from the Fukushima Daiichii Nuclear Power Plant following the 2011 TÅhoku 9.0 magnitude earthquake and tsunami (Great East Japan Earthquake and the resultant tsunami).
July 6, 1962 Sedan nuclear test accidentally released 33 PBq of radioactive iodine-131 and other radioactive material. 21 March–August 1962: radiation accident in Mexico City, four fatalities. 23 July 1964: Wood River Junction criticality accident. Resulted in 1 fatality; 1964, 1969: Santa Susana Field Laboratory, Los Angeles, California.
Unlike the Wolff–Chaikoff effect, the Plummer effect does not prevent the thyroid from taking up radioactive iodine, e.g. in the case of nuclear emergencies.Therefore, "plummering" with high-dose iodine is only effective in a short time window after the release of radionuclides. [9]
Only the Wolff–Chaikoff effect is helpful to prevent the thyroid from uptaking radioactive iodine in the case of nuclear emergencies. Therefore, "plummering" with high-dose iodine is only effective in a short time window after the release of radionuclides. [15] Wrong timing of iodine use may even increase the risk by triggering the Plummer ...
Toxic multinodular goiter can be treated with antithyroid medications such as propylthiouracil or methimazole, radioactive iodine, or with surgery. [5] Another treatment option is injection of ethanol into the nodules. [9] A Cochrane review compared treatments using recombinant human thyrotropin-aided radioactive iodine to radioactive iodine ...
For biological effects of substances such as radioactive iodine the ingestion of non-radioactive isotopes may substantially reduce the biological uptake of the radioactive form, and chelation therapy may be applied to accelerate the removal of radioactive materials formed from heavy metals from the body by natural processes.
