Instead, in vitro measurements provide an estimate of internally deposited iodine (both the stable and radioactive isotopes), utilizing techniques that measure iodine in body fluids, feces, or other human samples (Gautier 1983). (cdc.gov)
Because of the specificity of its uptake by the human body, radioactive isotopes of iodine can also be used to treat thyroid cancer . (wikipedia.org)
He inferred that this was a decay product of radioactive iodine -129. (wikidoc.org)
Stable isotope1
These in vivo measurement techniques are commonly used to measure body burdens of iodine radioisotopes, but cannot be used to assess the stable isotope of iodine. (cdc.gov)
Thermoelectric generators2
Can the Moon and the Mars import nuclear waste from Earth to power Radioisotope thermoelectric generators? (newmars.com)
Lucky for us though, taking onboard either Radioisotope Thermoelectric Generators (RTGs) or later relying on Photovoltaic Arrays (where the source of light radiation is more or less continuous and strong enough, i.e. in the inner Solar system) provides for relatively light, strong and long duration energy source (RTGs), or sustainable source of it, where it's readily available and merely need collecting (Solar Arrays).

Heaviest2
This period contains technetium, one of the two elements until lead that has no stable isotopes (along with promethium), as well as molybdenum and iodine, two of the heaviest elements with a known biological role, and Niobium has the largest magnetic known penetration depth of all the elements. (wikipedia.org)
In vivo measurements can be obtained through techniques that directly quantify internally-deposited iodine using, for example, thyroid or whole body counters. (cdc.gov)
The in vivo measurement of these radioisotopes within the body is performed with various radiation detectors and associated electronic devices that are collectively known as in vivo thyroid monitors or whole body counters, depending on the body site of interest. (cdc.gov)
Measurements2
The quantities of iodine within the body can be assessed through the use of bioassays that are comprised of in vivo measurements and/or in vitro measurements. (cdc.gov)
Finally, we present elementary measurements illustrating the detection capabilities of iodine-based compound semiconductor materials. (spie.org)
Neutron2
Generally speaking, the target nucleus of the radioisotope(s) to be treated is irradiated by gamma photons of an energy greater than the binding energy of the neutron in the target nucleus. (rexresearch.com)
Hand-Held RadioIsotope Identification Devices (HHRIID) are defined as a new class of portable neutron/gamma radiation detectors with specifications presented in the ANSI Standards N42.33 and N42.34. (spie.org)
Occurs1
The non-primordial radioisotope 79Se also occurs in minute quantities in uranium ores as a product of nuclear fission. (w3we.com)
We present some fundamental challenges in working with iodine-based semiconductors, including crystal growth issues and properties of the materials limiting radiation detector size, and the need for advanced electrode designs. (spie.org)
Gamma2
Iodine-based compound semiconductors may allow one to build a portable gamma-ray spectrometer with improved efficiency and energy resolution compared to many other portable spectrometer devices. (spie.org)
In addition, gamma-ray spectrometers made from iodine-based compound semiconductor materials have demonstrated energy resolutions (FWHM) less than 2% at 662 keV. (spie.org)
Instead, in vitro measurements provide an estimate of internally deposited iodine (both the stable and radioactive isotopes), utilizing techniques that measure iodine in body fluids, feces, or other human samples (Gautier 1983). (cdc.gov)
Spewing from the Fukushima reactor are radioactive isotopes including those of iodine (I-131), strontium (Sr-90) and cesium (Cs-134 and Cs-137) all of which are taken up in food and water. (myweathertech.com)
Neutrons1
Naturally-occurring iodine is a single isotope with 74 neutrons. (wikidoc.org)
Atmospheric1
Students who have seen the classroom demonstration in which iodine crystals are gently heated in a test tube to violet vapor, may gain the impression that liquid iodine does not exist at atmospheric pressure. (wikidoc.org)
Exposure1
The purpose of this chapter is to describe the analytical methods that are available for detecting, measuring, and/or monitoring iodine and its radioisotopes, their metabolites, and other biomarkers of exposure and effect to iodine and its radioisotopes. (cdc.gov)
K are found in all potassium, and it is the most common radioisotope in the human body. (wiki2.org)
Water6
The molecular iodine reacts reversibly with the negative ion, creating the triiodide anion, I 3 − , which dissolves well in water. (wikidoc.org)
Tincture of iodine (10% elemental iodine in ethanol base) is an essential component of any emergency survival kit, used both to disinfect wounds and to sanitize surface water for drinking (3 drops per litre, let stand for 30 minutes). (wikidoc.org)
the gas condenses, forming liquid H 2 O. For example, liquid water forms on the outside of a cold glass as the water vapor in the air is cooled by the cold glass, as seen in Figure 2 . (pressbooks.pub)
Condensation forms when water vapor in the air is cooled enough to form liquid water, such as (a) on the outside of a cold beverage glass or (b) in the form of fog. (pressbooks.pub)
Amount1
This misconception arises because the small amount of vapor produced has such a deep colour that the liquid appears not to form. (wikidoc.org)
Cold1
Courtois noted that the vapor crystallized on cold surfaces making dark crystals. (wikidoc.org)
Liquid2
In fact, if iodine crystals are heated carefully to just above their melting point of 113.7 °C, the crystals melt into a liquid which is present under a dense blanket of the vapor. (wikidoc.org)
It is a volatile reddish-brown liquid that gives off suffocating vapors, is corrosive to the skin, and may cause severe gastroenteritis if ingested. (nih.gov)
Chemical1
A large argument erupted between Davy and Gay-Lussac over who identified iodine first but both scientists acknowledged Courtois as the first to isolate the chemical element. (wikidoc.org)
Purpose1
Alcohol-free iodine solutions such as Lugol's iodine , as well as other iodophor type antiseptics, are also available as effective elemental iodine sources for this purpose. (wikidoc.org)
