Crossword clues for tritium
The Collaborative International Dictionary
tritium \trit"i*um\ (tr[i^]t"[i^]*[u^]m), n. (Chem.) A radioactive isotope of hydrogen having one proton and two neutrons in the nucleus. It decays spontaneously to Helium-3 by the emission of an electron (beta ray), with a half-life of 12.3 years. Symbol 1H3. Atomic weight 3.01605 (C-12 = 12.0000). It is one of the radioisotopes commonly used to label chemical compounds for use as tracers in biochemistry and chemistry. It is also used as one of the fusionable components of a hydrogen bomb.
Douglas Harper's Etymology Dictionary
1933, Modern Latin, from Greek tritos "third" (see third) + chemical suffix -ium.
Wiktionary
n. 1 (context isotope English) A radioactive isotope of the element hydrogen, (symbol T or (nuclide 3 1 H)), having one proton and two neutrons. 2 An atom of this isotope.
WordNet
n. a radioactive isotope of hydrogen; atoms of tritium have three times the mass of ordinary hydrogen atoms
Wikipedia
Tritium ( or ; symbol or , also known as hydrogen-3) is a radioactive isotope of hydrogen. The nucleus of tritium (sometimes called a triton) contains one proton and two neutrons, whereas the nucleus of protium (by far the most abundant hydrogen isotope) contains one proton and no neutrons. Naturally occurring tritium is extremely rare on Earth, where trace amounts are formed by the interaction of the atmosphere with cosmic rays. The name of this isotope is formed from the Greek word τρίτος (trítos) meaning "third".
Tritium is a simple scripting language for efficiently transforming structured data like HTML, XML, and JSON. It is similar in purpose to XSLT but has a syntax influenced by JQuery, Sass, and CSS versus XSLT’s XML based syntax.
Usage examples of "tritium".
Current reactor concepts cleverly use the neutron flux from the fusion reactor itself to make more tritium, solving some of the neutron contamination problem at the same time, but it would be nice if we could tap into fusion power without having to deal with radioactive waste at all, and preferably without using exotic and expensive isotopes either.
He learned that the geologists had predicted a subterranean pocket of tritium oxide ice at sixteen thousand feet, and that it was for this that they were drilling.
The pockets of tritium ice catch a few neutrons from uranium oredown under.
Such a reply might have been satisfactory for an iron mine or an oil well or a stone quarry, but tritium suggested hydrogen-fusion.
They had spent a year of hard labour on what they had thought to be a tritium well, but now that it was done, there were no facilities for pumping the stuff or hauling it away.
Some fool with a slip-stick would hear about it, and calculate what would happen to Mars if five cubic miles of tritium ice detonated in one split second.
It seems likely that in another century we will have practical power schemes that involve the controlled fusion of deuterium and tritium, and of deuterium and helium.
Its not sophisticated, and we cant get the deuterium or the tritium to make a thermonuclear device, but what we have is capable of taking out Timshel City.
A rumor had spread through the civilians in the Nautilus that the High Guard had found seven hundred and thirty-two bombs ready to go, with component parts for many more, plus enough deuterium and tritium to make up about a dozen H bombs.
Now god is the force of nature itself, the fusion of tritium and deuterium.
When they reached the corridor Sigmund had extinguished the overhead fluorescent panels, and was observing his discovery against the background under the dim illumination of the tritium safety lamps.
But the pressure tanks of the life-support system were actually cryocontainers with deuterium and tritium, and the heater batteries were heavy duty capacitors for the laser assembly.
DEUS therefore excited the hydrogen with injections of tritium until the synthesis finally started.
Just unscrew the nose and slide out the workings until you see the cup where the tritium goes.
They were one step away from assembling a functional bomb, and unless she could locate the tritium, they might just as well have played tongo until their whole world rolled to an end.
