  • Tritium (periodic symbol T or H3 and is derived from the Greek word tritos, meaning "third") is a radioactive isotope of hydrogen and is naturally very rare where trace amounts are created from atmospheric-cosmic ray interactions. It is produced artificially by irradiating lithium or lithium-ceramic in a nuclear reactor. Aside from a common use of light sources for watches or instruments; like deuterium, it is used as fuel for nuclear fusion in energy generation and nuclear weapons.
