Tritium is both natural and artificial. It 'very useful for watch dials and other displays that can be read at night.
Tritium is a radioactive isotope of hydrogen element. The chemical symbol for hydrogen is H. Tritium, a symbol of H3, is produced naturally in the atmosphere by the reaction of cosmic rays and air molecules. It 'also produced in nuclear reactors to produce electricity. Tritium is composed of a hydrogen atom with one proton and 2neutrons gives an atomic weight of 3.

Tritium has a half life of about 12-1/2 years. This means that 1 / 2 the original amount that decays in 12-1/2 years. Although this is relatively short half-life of radioactive materials in the world, this gives some useful properties of tritium. When encapsulated tritium watches, exit signs, gauges, aircraft and other applications, it lights up to a maximum of 25 years.
The radioactive decay of tritium is not dangerous to humans in theseapplications because it emits very weak beta particles can be stopped even for a piece of paper. Because tritium is encapsulated in small packages made of glass or plastic, the radiation reaches the skin.
The advantages of this decline is a bright screen that can be easily read at night. The light emitted is not visible during the day but at night the light is very visible. This makes it very popular tritium for night vision applications. 'S, military pilots, police and othervisibility, without having to press any key to read the screen.
Different manufacturers use tritium watches screens for their screens. They have screens that far exceed the brightness of the light that ordinary watch dial call the "weight" of exposure to light. These styles have become very popular look among the general public as well as pilots and military police.
Tritium watches come in many styles and prices. There is a stylefor almost everyone. Now you can tell the time in the dark and be fashionable at the same time.
