In that location are 37 known isotopes of iodine (53I) from 108I to 144I; all undergo radioactivity except 127I, which is stable. Iodine is thus a monoisotopic element.
Its longest-lived radioactive isotope, 129I, has a half-life of xv.7 million years, which is far also brusque for information technology to exist equally a primordial nuclide. Cosmogenic sources of 129I produce very tiny quantities of it that are too small to bear upon atomic weight measurements; iodine is thus besides a mononuclidic element—one that is found in nature only as a unmarried nuclide. Most 129I derived radioactivity on Earth is human-made, an unwanted long-lived byproduct of early nuclear tests and nuclear fission accidents.
All other iodine radioisotopes accept half-lives less than 60 days, and four of these are used as tracers and therapeutic agents in medicine. These are 123I, 124I, 125I, and 131I. All industrial production of radioactive iodine isotopes involves these 4 useful radionuclides.
The isotope 135I has a half-life less than vii hours, which is too short to exist used in biology. Unavoidable in situ production of this isotope is important in nuclear reactor command, every bit it decays to 135Xe, the most powerful known neutron cushion, and the nuclide responsible for the so-called iodine pit phenomenon.
In addition to commercial production, 131I (half-life eight days) is ane of the mutual radioactive fission products of nuclear fission, and is thus produced inadvertently in very large amounts inside nuclear reactors. Due to its volatility, short half-life, and high abundance in fission products, 131I (along with the short-lived iodine isotope 132I, which is produced from the decay of 132Te with a half-life of three days) is responsible for the largest part of radioactive contamination during the first week later accidental environmental contagion from the nuclear waste from a nuclear power plant. Thus highly dosed iodine supplements (usually potassium iodide) are given to the populace after nuclear accidents or explosions (and in some cases prior to whatever such incident as a civil defense mechanism) to reduce the uptake of radioactive iodine compounds by the thyroid before the highly radioactive isotopes have had fourth dimension to disuse.

Notable radioisotopes [edit]
Radioisotopes of iodine are called radioactive iodine or radioiodine. Dozens exist, but nearly a one-half dozen are the most notable in applied sciences such as the life sciences and nuclear ability, as detailed below. Mentions of radioiodine in wellness care contexts refer more than frequently to iodine-131 than to other isotopes.
Of the many isotopes of iodine, only two are typically used in a medical setting: iodine-123 and iodine-131. Since 131I has both a beta and gamma decay mode, it can be used for radiotherapy or for imaging. 123I, which has no beta action, is more than suited for routine nuclear medicine imaging of the thyroid and other medical processes and less damaging internally to the patient. In that location are some situations in which iodine-124 and iodine-125 are also used in medicine.[4]
Due to preferential uptake of iodine past the thyroid, radioiodine is extensively used in imaging of and, in the case of 131I, destroying dysfunctional thyroid tissues. Other types of tissue selectively take up certain iodine-131-containing tissue-targeting and killing radiopharmaceutical agents (such equally MIBG). Iodine-125 is the only other iodine radioisotope used in radiation therapy, but simply equally an implanted capsule in brachytherapy, where the isotope never has a gamble to exist released for chemical interaction with the body'due south tissues.
Iodine-123 and iodine-125 [edit]
The gamma-emitting isotopes iodine-123 (half-life xiii hours), and (less commonly) the longer-lived and less energetic iodine-125 (one-half-life 59 days) are used every bit nuclear imaging tracers to evaluate the anatomic and physiologic office of the thyroid. Abnormal results may be caused by disorders such as Graves' illness or Hashimoto'due south thyroiditis. Both isotopes decay by electron capture (EC) to the corresponding tellurium nuclides, merely in neither example are these the metastable nuclides 123mTe and 125mTe (which are of higher energy, and are not produced from radioiodine). Instead, the excited tellurium nuclides disuse immediately (half-life besides short to notice). Following EC, the excited 123Te from 123I emits a loftier-speed 127 keV internal conversion electron (non a beta ray) about thirteen% of the time, but this does piffling cellular damage due to the nuclide'due south curt one-half-life and the relatively small fraction of such events. In the rest of cases, a 159 keV gamma ray is emitted, which is well-suited for gamma imaging.
Excited 125Te resulting from electron capture of 125I also emits a much lower-free energy internal conversion electron (35.5 keV), which does relatively piddling damage due to its low free energy, even though its emission is more mutual. The relatively low-energy gamma from 125I/125Te disuse is poorly suited for imaging, but can all the same be seen, and this longer-lived isotope is necessary in tests that crave several days of imaging, for example, fibrinogen scan imaging to detect claret clots.
Both 123I and 125I emit copious low energy Auger electrons after their decay, but these do not cause serious damage (double-stranded Deoxyribonucleic acid breaks) in cells, unless the nuclide is incorporated into a medication that accumulates in the nucleus, or into Deoxyribonucleic acid (this is never the case is clinical medicine, just it has been seen in experimental beast models).[5]
Iodine-125 is too commonly used past radiation oncologists in low dose charge per unit brachytherapy in the handling of cancer at sites other than the thyroid, specially in prostate cancer. When 125I is used therapeutically, information technology is encapsulated in titanium seeds and implanted in the area of the tumor, where information technology remains. The low energy of the gamma spectrum in this example limits radiations impairment to tissues far from the implanted sheathing. Iodine-125, due to its suitable longer half-life and less penetrating gamma spectrum, is also ofttimes preferred for laboratory tests that rely on iodine as a tracer that is counted by a gamma counter, such as in radioimmunoassaying.
125I is used as the radiolabel in investigating which ligands go to which plant pattern recognition receptors (PRRs).[vi]
Iodine-124 [edit]
Iodine-124 is a proton-rich isotope of iodine with a half-life of 4.18 days. Its modes of decay are: 74.iv% electron capture, 25.half-dozen% positron emission. 124I decays to 124Te. Iodine-124 can be made past numerous nuclear reactions via a cyclotron. The most common starting textile used is 124Te.
Iodine-124 every bit the iodide salt tin be used to directly image the thyroid using positron emission tomography (PET).[7] Iodine-124 can also be used equally a PET radiotracer with a usefully longer one-half-life compared with fluorine-18.[eight] In this use, the nuclide is chemically bonded to a pharmaceutical to form a positron-emitting radiopharmaceutical, and injected into the body, where again it is imaged by PET scan.
Iodine-129 [edit]
Iodine-129 (129I; half-life fifteen.7 one thousand thousand years) is a product of cosmic ray spallation on various isotopes of xenon in the atmosphere, in cosmic ray muon interaction with tellurium-130, and besides uranium and plutonium fission, both in subsurface rocks and nuclear reactors. Bogus nuclear processes, in particular nuclear fuel reprocessing and atmospheric nuclear weapons tests, have now swamped the natural signal for this isotope. All the same, it at present serves equally a groundwater tracer equally indicator of nuclear waste dispersion into the natural environment. In a like style, 129I was used in rainwater studies to rails fission products following the Chernobyl disaster.
In some ways, 129I is similar to 36Cl. It is a soluble halogen, exists mainly as a not-sorbing anion, and is produced by cosmogenic, thermonuclear, and in-situ reactions. In hydrologic studies, 129I concentrations are usually reported as the ratio of 129I to total I (which is virtually all 127I). As is the instance with 36Cl/Cl, 129I/I ratios in nature are quite small-scale, ten−xiv to 10−10 (top thermonuclear 129I/I during the 1960s and 1970s reached about 10−7). 129I differs from 36Cl in that its one-half-life is longer (15.vii vs. 0.301 million years), information technology is highly biophilic, and occurs in multiple ionic forms (commonly, I− and IO3 −), which have different chemical behaviors. This makes it fairly easy for 129I to enter the biosphere as it becomes incorporated into vegetation, soil, milk, brute tissue, etc. Excesses of stable 129Xe in meteorites have been shown to upshot from disuse of "primordial" iodine-129 produced newly by the supernovas that created the dust and gas from which the solar arrangement formed. This isotope has long decayed and is thus referred to equally "extinct". Historically, 129I was the offset extinct radionuclide to be identified as present in the early on Solar Arrangement. Its disuse is the basis of the I-Xe iodine-xenon radiometric dating scheme, which covers the get-go 85 million years of Solar Organization evolution.
Iodine-131 [edit]
Iodine-131 ( 131
I
) is a beta-emitting isotope with a half-life of eight days, and comparatively energetic (190 keV boilerplate and 606 keV maximum energy) beta radiation, which penetrates 0.half dozen to 2.0 mm from the site of uptake. This beta radiation tin can exist used for the destruction of thyroid nodules or hyperfunctioning thyroid tissue and for elimination of remaining thyroid tissue afterward surgery for the treatment of Graves' affliction. The purpose of this therapy, which was offset explored past Dr. Saul Hertz in 1941,[9] is to destroy thyroid tissue that could not be removed surgically. In this procedure, 131I is administered either intravenously or orally following a diagnostic scan. This procedure may too exist used, with college doses of radio-iodine, to treat patients with thyroid cancer.
The 131I is taken up into thyroid tissue and concentrated there. The beta particles emitted by the radioisotope destroys the associated thyroid tissue with little harm to surrounding tissues (more than 2.0 mm from the tissues absorbing the iodine). Due to similar destruction, 131I is the iodine radioisotope used in other water-soluble iodine-labeled radiopharmaceuticals (such as MIBG) used therapeutically to destroy tissues.
The high energy beta radiations (up to 606 keV) from 131I causes information technology to be the most carcinogenic of the iodine isotopes. It is idea to crusade the majority of backlog thyroid cancers seen later nuclear fission contamination (such as bomb fallout or astringent nuclear reactor accidents like the Chernobyl disaster) However, these epidemiological effects are seen primarily in children, and treatment of adults and children with therapeutic 131I, and epidemiology of adults exposed to low-dose 131I has not demonstrated carcinogenicity.[x]
Iodine-135 [edit]
Iodine-135 is an isotope of iodine with a half-life of 6.half dozen hours. It is an important isotope from the viewpoint of nuclear reactor physics. It is produced in relatively large amounts equally a fission product, and decays to xenon-135, which is a nuclear poison with a very large thermal neutron cantankerous department, which is a crusade of multiple complications in the command of nuclear reactors. The process of buildup of xenon-135 from accumulated iodine-135 can temporarily preclude a shut-down reactor from restarting. This is known as xenon poisoning or "falling into an iodine pit".
Iodine-128 and other isotopes [edit]
Iodine fission-produced isotopes not discussed above (iodine-128, iodine-130, iodine-132, and iodine-133) have half-lives of several hours or minutes, rendering them well-nigh useless in other applicable areas. Those mentioned are neutron-rich and undergo beta decay to isotopes of xenon. Iodine-128 (half-life 25 minutes) can decay to either tellurium-128 by electron capture or to xenon-128 past beta disuse. It has a specific radioactivity of 2.177×106 TBq/g.
Nonradioactive iodide (127I) as protection from unwanted radioiodine uptake by the thyroid [edit]
Colloquially, radioactive materials can be described every bit "hot," and non-radioactive materials can be described as "common cold." There are instances in which cold iodide is administered to people in order to forbid the uptake of hot iodide by the thyroid gland. For instance, blockade of thyroid iodine uptake with potassium iodide is used in nuclear medicine scintigraphy and therapy with some radioiodinated compounds that are non targeted to the thyroid, such as iobenguane (MIBG), which is used to image or treat neural tissue tumors, or iodinated fibrinogen, which is used in fibrinogen scans to investigate clotting. These compounds contain iodine, merely not in the iodide form. Notwithstanding, since they may be ultimately metabolized or intermission down to radioactive iodide, information technology is common to administrate non-radioactive potassium iodide to insure that metabolites of these radiopharmaceuticals is not sequestered by thyroid gland and inadvertently administer a radiological dose to that tissue.
Potassium iodide has been distributed to populations exposed to nuclear fission accidents such as the Chernobyl disaster. The iodide solution SSKI, a saturated solution of potassium (Thou) iodide in water, has been used to block assimilation of the radioiodine (it has no result on other radioisotopes from fission). Tablets containing potassium iodide are now also manufactured and stocked in central disaster sites by some governments for this purpose. In theory, many harmful late-cancer effects of nuclear fallout might exist prevented in this style, since an excess of thyroid cancers, presumably due to radioiodine uptake, is the only proven radioisotope contamination effect subsequently a fission blow, or from contamination by fallout from an atomic flop (prompt radiation from the bomb also causes other cancers, such as leukemias, directly). Taking large amounts of iodide saturates thyroid receptors and prevents uptake of most radioactive iodine-131 that may exist present from fission production exposure (although it does not protect from other radioisotopes, nor from any other grade of direct radiations). The protective issue of KI lasts approximately 24 hours, so must be dosed daily until a gamble of pregnant exposure to radioiodines from fission products no longer exists.[11] [12] Iodine-131 (the most common radioiodine contaminant in fallout) also decays relatively rapidly with a half-life of eight days, and then that 99.95% of the original radioiodine has vanished later on iii months.
