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.

氚（Tritium）是氢的一种放射性同位素，原子核内含一个质子和两个中子。 由于其放射性，氚在自然界中极为稀少，主要通过人工方式生产，如核反应堆中的锂核反应。 氚具有广泛的应用价值：在军事领域，它是核武器聚变材料的重要组成部分；在科学研究中，氚常作为示踪剂用于化学、生物学和医学研究，帮助追踪物质的流动和转化；在工业和日常生活中，氚的自发光特性使其被广泛应用于氚灯、手表夜光涂层和紧急照明标志等。 然而，氚的放射性也带来了安全挑战。 虽然其β …

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

Tritium (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.

Its symbol is 3H, or T. Tritium atoms are unstable and disintegrate radioactively, forming stable 3He atoms. The radioactive decay is accompanied by the emission of [1 particles, measurable in specific laboratories ...

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.

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.

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 nucleus of the tritium atom, called a triton, contains one proton and two neutrons. The word tritium comes from the Greek word tritos, which means “third.”

2024年6月5日 · Tritium is the name given to the hydrogen-3 isotope. Its symbol is 3H, in which the 3 superscript represents the mass number of tritium, which has one proton and two neutrons in its nucleus.

Tritium (3 H; T): An isotope of hydrogen whose nucleus contains one proton and two neutrons.Commonly abbreviated as T, for example, in T 2 O (water containing two 3 H atoms).
