Tritium (from Ancient Greek τρίτος (trítos) 'third') or hydrogen-3 (symbol T or 3 H) is a rare and radioactive isotope of hydrogen with a half-life of ~12.3 years. The tritium nucleus (t, sometimes called a triton) contains one proton and two neutrons, whereas the nucleus of the common isotope hydrogen-1 (protium) contains one proton and no neutrons, and that of non-radioactive hydrogen ...
Tritium excretion can be accelerated further by increasing water intake to 3–4 liters/day. [11] Direct, short-term exposure to small amounts of tritium is mostly harmless. If a tritium tube breaks, one should leave the area and allow the gas to diffuse into the air. Tritium exists naturally in the environment, but in very small quantities.

HTO has a short biological half-life in the human body of 7 to 14 days, which both reduces the total effects of single-incident ingestion and precludes long-term bioaccumulation of HTO from the environment. The biological half life of tritiated water in the human body, which is a measure of body water turn-over, varies with the season.
In metabolism research, tritium and 14 C-labeled glucose are commonly used in glucose clamps to measure rates of glucose uptake, fatty acid synthesis, and other metabolic processes. [9] While radioactive tracers are sometimes still used in human studies, stable isotope tracers such as 13 C are more commonly used in current human clamp studies.

Tritium is a low-energy beta emitter commonly used as a radiotracer in research and in traser [check spelling] self-powered lightings. The half-life of tritium is 12.3 years. The electrons from beta emission from tritium are so low in energy (average decay energy 5.7 keV) that a Geiger counter cannot be used to detect them. An advantage of the ...
H. P. Lovecraft, writer and creator of cosmicism.. Cosmicism is American author H. P. Lovecraft's name for the literary philosophy he developed and used for his fiction. [1] [2] Lovecraft was a writer of horror stories that involve occult phenomena like astral possession and alien miscegenation, and the themes of his fiction over time contributed to the development of this philosophy.
