Dating wine tritium

However, if the atoms have a high enough temperature and pressure (for example, in the core of the Sun), then their random motions can overcome such electrical repulsion (called the Coulomb force), and they can come close enough for the strong nuclear force to take effect, fusing them into heavier atoms.

The tritium nucleus, containing one proton and two neutrons, has the same charge as the nucleus of ordinary hydrogen, and it experiences the same electrostatic repulsive force when brought close to another atomic nucleus.

Beta particles from tritium can penetrate only about 6.0 mm of air, and they are incapable of passing through the dead outermost layer of human skin.

The unusually low energy released in the tritium beta decay makes the decay (along with that of rhenium-187) appropriate for absolute neutrino mass measurements in the laboratory (the most recent experiment being KATRIN).

In January 2014 it was made public that a total of 875 TBq (2.45 g) of tritium are on the site of Fukushima Daiichi, Worldwide, the production of tritium from natural sources is 148,000 terabecquerels per year.

The global equilibrium inventory of tritium created by natural sources remains approximately constant at 2,590,000 terabecquerels.

, also known as hydrogen-3) is a radioactive isotope of hydrogen.

The high levels of atmospheric nuclear weapons testing that took place prior to the enactment of the Partial Test Ban Treaty proved to be unexpectedly useful to oceanographers.The release or recovery of tritium needs to be considered in the operation of nuclear reactors, especially in the reprocessing of nuclear fuels and in the storage of spent nuclear fuel.The production of tritium is not a goal, but rather a side-effect.The low energy of tritium's radiation makes it difficult to detect tritium-labeled compounds except by using liquid scintillation counting.Tritium is produced in nuclear reactors by neutron activation of lithium-6.

While tritium has several different experimentally determined values of its half-life, the National Institute of Standards and Technology lists and it releases 18.6 ke V of energy in the process.
