Tritium (from Ancient Greek τρίτος (trítos) 'third') or hydrogen-3 (symbol T or 3 H) is a rare and radioactive isotope of hydrogen with a half-life of ~12.3 years. The tritium nucleus (t, sometimes called a triton) contains one proton and two neutrons, whereas the nucleus of the common isotope hydrogen-1 (protium) contains one proton and no neutrons, and that of non-radioactive hydrogen ...
Tritium excretion can be accelerated further by increasing water intake to 3–4 liters/day. [11] Direct, short-term exposure to small amounts of tritium is mostly harmless. If a tritium tube breaks, one should leave the area and allow the gas to diffuse into the air. Tritium exists naturally in the environment, but in very small quantities.
Tritium can be used in chemical and biological labeling experiments as a radioactive tracer. [ 16 ] [ 17 ] Deuterium–tritium fusion uses 2 H and 3 H as its main reactants, giving energy through the loss of mass when the two nuclei collide and fuse at high temperatures.
As tritium forms a stable compound with oxygen (tritiated water) while helium-3 does not, the storage and collection process could continuously collect the material that outgasses from the stored material. Tritium is a critical component of nuclear weapons and historically it was produced and stockpiled primarily for this application. The decay ...
Tritium activities are suspended while personnel gather information about the event, the report said. The lab plans to vent four barrels of tritium-laced legacy waste, releasing radioactive vapors ...
Hydrogen gas is highly flammable: 2 H 2 (g) + O 2 (g) ... Tritium has also been used in chemical and biological labeling experiments as a radiolabel. [52]
Heavy water that has been used as a coolant in nuclear power plants contains substantially more tritium as a result of neutron bombardment of the deuterium in the heavy water (tritium is a health risk when ingested in large quantities).
Deuterium and tritium are both considered first-generation fusion fuels; they are the easiest to fuse, because the electrical charge on their nuclei is the lowest of all elements. The three most commonly cited nuclear reactions that could be used to generate energy are: 2 H + 3 H → n (14.07 MeV) + 4 He (3.52 MeV)
