• iodide
  • Iodine occurs in many oxidation states, including iodide (I−), iodate (IO− 3), and the various periodate anions. (wikipedia.org)
  • The inner walls of the capsule are then rinsed with dilute NaOH solution to collect iodine as soluble iodide and hypoiodite OI−, according to the standard disproportionation reaction of halogens in alkaline solutions. (wikipedia.org)
  • 125I
  • Iodine-125 (125I) is a radioisotope of iodine which has uses in biological assays, nuclear medicine imaging and in radiation therapy as brachytherapy to treat a number of conditions, including prostate cancer, uveal melanomas, and brain tumors. (wikipedia.org)
  • Iodine-125 itself has a neutron capture cross section of 900 barns, and consequently during a long irradiation, part of the 125I formed will be converted to 126I, a beta-emitter and positron-emitter with a half-life of 13.1 days, which is not medically useful. (wikipedia.org)
  • vapor
  • It was Gay-Lussac who suggested the name "iode", from the Greek word ἰοειδής (ioeidēs) for violet (because of the colour of iodine vapor). (wikipedia.org)
  • More commonly, powdered elemental tellurium is irradiated and then I-131 separated from it by dry distillation of the iodine, which has a far higher vapor pressure. (wikipedia.org)
  • isolate
  • Arguments erupted between Davy and Gay-Lussac over who identified iodine first, but both scientists acknowledged Courtois as the first to isolate the element. (wikipedia.org)
  • tissues
  • Thus, iodine-131 is increasingly less employed in small doses in medical use (especially in children), but increasingly is used only in large and maximal treatment doses, as a way of killing targeted tissues. (wikipedia.org)
  • selectively
  • Nuclear imaging is non-invasive and has high sensitivity, and nanoparticles are useful as a platform for combining multiple copies of targeting vectors and effectors in order to selectively deliver radioisotopes to a specific region of interest. (wikipedia.org)
  • nuclear medicine
  • Iodine-131 can be "seen" by nuclear medicine imaging techniques (i.e., gamma cameras) whenever it is given for therapeutic use, since about 10% of its energy and radiation dose is via gamma radiation. (wikipedia.org)
  • Medical
  • Much smaller incidental doses of iodine-131 than those used in medical therapeutic procedures, are supposed by some studies to be the major cause of increased thyroid cancers after accidental nuclear contamination. (wikipedia.org)
  • acid
  • Iodine is also used as a catalyst in the industrial production of acetic acid and some polymers. (wikipedia.org)
  • radiation
  • By contrast, other iodine radioisotopes are usually created by far more expensive techniques, starting with reactor radiation of expensive capsules of pressurized xenon gas. (wikipedia.org)
  • Iodine-125 has been used in scanning/imaging the thyroid, but iodine-123 is preferred for this purpose, due to better radiation penetration and shorter half-life (13 hours). (wikipedia.org)
  • methods
  • The low-cost availability of I-131, in turn, is due to the relative ease of creating I-131 by neutron bombardment of natural tellurium in a nuclear reactor, then separating I-131 out by various simple methods (i.e., heating to drive off the volatile iodine). (wikipedia.org)
  • solution
  • The purpose of this study is to find out if chlorhexidine gluconate solution is better at reducing the rate of wound infection after cesarean section compared to povidone-iodine. (bioportfolio.com)
