Tritium (from Ancient Greek τρίτος (trítos) 'third') or hydrogen-3 (symbol T or 3H) is a rare and radioactive isotope of hydrogen with a half-life of ~12.33 years.

2025年2月6日 · Tritium is a hydrogen atom that has two neutrons in the nucleus and one proton. It is radioactive and behaves like other forms of hydrogen in the environment. Tritium is produced naturally in the upper atmosphere and as a byproduct of nuclear fission.

2025年2月25日 · Tritium, (T, or 3H), the isotope of hydrogen with atomic weight of approximately 3. Its nucleus, consisting of one proton and two neutrons, has triple the mass of the nucleus of ordinary hydrogen. Tritium is a radioactive species having a half-life of 12.32 years; it occurs in natural water with an

2020年1月9日 · Tritium is the radioactive isotope of the element hydrogen. It has many useful applications. Tritium is also known as hydrogen-3 and has an element symbol T or 3 H. The nucleus of a tritium atom is called a triton and consists of three particles: one proton and two neutrons. The word tritium comes from Greek the word "tritos", which means "third".

Tritium is a prospective fuel in the effort to develop commercially viable nuclear fusion reactors. Tritium is also a critical component in modern nuclear weapons, and an inventory of tritium is maintained for this purpose.

What is Tritium? Tritium is a form of hydrogen that is radioactive, and like hydrogen it reacts with oxygen to form water. Tritium is produced naturally in the upper atmosphere when cosmic rays strike atmospheric gases. Tritium can also be produced by man during nuclear weapon explosions, in reactors intended to produce tritium for nuclear

Tritium is a radioactive isotope, but it emits a very weak form of radiation, a low-energy beta particle similar to an electron. It is a pure beta emitter (i.e., beta emitter without accompanying gamma radiation).
