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 ...
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.
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.
The human body naturally contains deuterium equivalent to about five grams of heavy water, which is harmless. When a large fraction of water (> 50%) in higher organisms is replaced by heavy water, the result is cell dysfunction and death. [6] Heavy water was first produced in 1932, a few months after the discovery of deuterium. [7]
The danger is in the DIET. There is no mystery behind weight. It's 2014 and like many people, you may be resolving to lose weight. It's a great resolution. Maintaining a healthy weight is ...
In addition to stripping nutrients from your diet, you risk raising your cholesterol and LDL (bad cholesterol) levels by eating a carnivore diet, explains Antonette Hardie, M.S., R.D.N., a ...
Human nutrition deals with the provision of essential nutrients in food that are necessary to support human life and good health. [1] Poor nutrition is a chronic problem often linked to poverty, food security , or a poor understanding of nutritional requirements. [ 2 ]
Critics have long argued that while studying the effects of Red Dye No. 3 in humans poses ethical and scientific challenges, its ban in cosmetics should have logically extended to the food supply ...
