, 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.

With the Strategic Arms Reduction Treaty (START) after the end of the Cold War, the existing supplies were sufficient for the new, smaller number of nuclear weapons for some time.

The production of tritium was resumed with irradiation of rods containing lithium (replacing the usual control rods containing boron, cadmium, or hafnium), at the reactors of the commercial Watts Bar Nuclear Generating Station in 2003–2005 followed by extraction of tritium from the rods at the new Tritium Extraction Facility All atomic nuclei, being composed of protons and neutrons, repel one another because of their positive charge.

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.and it releases 18.6 ke V of energy in the process.The electron's kinetic energy varies, with an average of 5.7 ke V, while the remaining energy is carried off by the nearly undetectable electron antineutrino.This is due to a fixed production rate and losses proportional to the inventory.According to the Institute for Energy and Environmental Research report in 1996 about the U. Department of Energy, only 225 kg (496 lb) of tritium has been produced in the United States since 1955.

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.
