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

Hydrogen (1 H) has three naturally occurring isotopes: 1 H, 2 H, and 3 H. 1 H and 2 H are stable, while 3 H has a half-life of 12.33 (2) years. [3][nb 1] Heavier isotopes also exist; all are synthetic and have a half-life of less than 1 zeptosecond (10 −21 s). [4][5] Of these, 5 H is the least stable, while 7 H is the most.

Hydrogen-3 - also known as tritium - is a radioactive isotope of hydrogen that occurs naturally in very small amounts in the atmosphere. It has a half-life of about 12.3 years and beta decays into helium-3. Tritium is used in the nuclear industry as a fuel in nuclear reactors and in the manufacture of nuclear weapons.

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).

In general terms, tritium is the radioactive form of hydrogen (3 H). This rare radioactive substance is relatively safe for commercial, military, and scientific applications. Let’s examine closer tritium 3H: what it is and what it’s used for. Curious about the …

Tritium, often known as hydrogen-3 ( tritium symbol T or 3H), is a radioactive isotope of hydrogen that is extremely rare. Tritium (also known as a triton) has one proton and two neutrons in its nucleus, whereas the common isotope hydrogen-1 (protium) has only one proton and hydrogen-2 (deuterium) has one proton and one neutron in its nucleus.

Tritium is the only radioactive isotope1 of hydrogen and it is commonly represented by the chemical symbol H-3, 3H, or simply T. Being radioactive causes tritium to undergo a process of radioactive decay.

Tritium (3H) is the only radioactive isotope of hydrogen, and has a half-life of 12.43 years (Unterweger et al., 1980). Large quantities of tritium were introduced into the hydrological cycle by atmospheric thermonuclear testing in the 1950s and 1960s, providing a...

2024年6月18日 · Tritium is the radioactive isotope of the element hydrogen. It is also known as hydrogen-3 or using the shorthand notation T or 3 H in chemical formulas and reactions. The …
