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 ...
The generic equation is: A Z X → A Z+1 X′ + e − + ν e [1] where A and Z are the mass number and atomic number of the decaying nucleus, and X and X′ are the initial and final elements, respectively. Another example is when the free neutron (1 0 n) decays by β − decay into a proton (p): n → p + e − + ν e.
Hydrogen (1 H) has three naturally occurring isotopes: 1 H, 2 H, and 3 H. 1 H and 2 H are stable, while 3 H has a half-life of 12.32(2) years. [3] [nb 1] Heavier isotopes also exist; all are synthetic and have a half-life of less than 1 zeptosecond (10 −21 s).
An important property of helium-3, which distinguishes it from the more common helium-4, is that its nucleus is a fermion since it contains an odd number of spin 1 ⁄ 2 particles. Helium-4 nuclei are bosons, containing an even number of spin 1 ⁄ 2 particles. This is a direct result of the addition rules for quantized angular momentum.
The DTF reaction. Deuterium–tritium fusion (DTF) is a type of nuclear fusion in which one deuterium (2 H) nucleus (deuteron) fuses with one tritium (3 H) nucleus (triton), giving one helium-4 nucleus, one free neutron, and 17.6 MeV of total energy coming from both the neutron and helium.
Tritium is a low-energy beta emitter commonly used as a radiotracer in research and in traser [check spelling] self-powered lightings.The half-life of tritium is 12.3 years. The electrons from beta emission from tritium are so low in energy (average decay energy 5.7 keV) that a Geiger counter cannot be used to detect the
Tritium radioluminescence is the use of gaseous tritium, a radioactive isotope of hydrogen, to create visible light. Tritium emits electrons through beta decay and, ...
In its pure form it may be called tritium oxide (T 2 O or 3 H 2 O) or super-heavy water. Pure T 2 O is a colorless liquid, [ 1 ] and it is corrosive due to self- radiolysis . Diluted, tritiated water is mainly H 2 O plus some HTO ( 3 HOH).
