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.
This is a complete list of works by H. P. Lovecraft.Dates for the fiction, collaborations and juvenilia are in the format: composition date / first publication date, taken from An H. P. Lovecraft Encyclopedia by S. T. Joshi and D. E. Schultz, Hippocampus Press, New York, 2001.
The Toxin and Toxin-Target Database (T3DB), [1] [2] also known as the Toxic Exposome Database, is a freely accessible online database of common substances that are toxic to humans, along with their protein, DNA or organ targets. The database currently houses nearly 3,700 toxic compounds or poisons described by nearly
Scientists continue to unravel the startling history of all the toxic chemicals — and now radioactive waste — that have been dumped off the Los Angeles coast. It's not just toxic chemicals.
The Elder Things (also known as the Old Ones [1] and Elder Ones [2]) are fictional extraterrestrials in the Cthulhu Mythos.The beings first appeared in H. P. Lovecraft's novella, At the Mountains of Madness (published in 1936, but written in 1931), and later appeared, although not named, in the short story "The Dreams in the Witch-House" ().
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 ...
