  2. Biological half-life - Wikipedia

    en.wikipedia.org/wiki/Biological_half-life

    The biological half-life of water in a human is about 7 to 14 days. It can be altered by behavior. Drinking large amounts of alcohol will reduce the biological half-life of water in the body. [8] [9] This has been used to decontaminate patients who are internally contaminated with tritiated water. The basis of this decontamination method is to ...

  3. Tritiated water - Wikipedia

    en.wikipedia.org/wiki/Tritiated_water

    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.

  4. Half-life - Wikipedia

    en.wikipedia.org/wiki/Half-life

    For example, the biological half-life of water in a human being is about 9 to 10 days, [9] though this can be altered by behavior and other conditions. The biological half-life of caesium in human beings is between one and four months.

  5. Tritium - Wikipedia

    en.wikipedia.org/wiki/Tritium

    [40] [46] The biological half-life of tritiated water in the human body, which is a measure of body water turn-over, varies with the season. Studies on the biological half-life of occupational radiation workers for free water tritium in a coastal region of Karnataka, India, show that the biological half-life in winter is twice that of the ...

  6. Properties of water - Wikipedia

    en.wikipedia.org/wiki/Properties_of_water

    Water (H 2 O) is a polar inorganic compound that is at room temperature a tasteless and odorless liquid, which is nearly colorless apart from an inherent hint of blue.It is by far the most studied chemical compound [20] and is described as the "universal solvent" [21] and the "solvent of life". [22]

  7. Uranium in the environment - Wikipedia

    en.wikipedia.org/wiki/Uranium_in_the_environment

    Chemical toxicity can cause public health issues when uranium is present in groundwater, especially if concentrations in food and water are increased by mining activity. [1] The biological half-life (the average time it takes for the human body to eliminate half the amount in the body) for uranium is about 15 days. [3]

  8. Water - Wikipedia

    en.wikipedia.org/wiki/Water

    Water is an inorganic compound with the chemical formula H 2 O.It is a transparent, tasteless, odorless, [c] and nearly colorless chemical substance.It is the main constituent of Earth's hydrosphere and the fluids of all known living organisms (in which it acts as a solvent [20]).

  9. Health effects of radon - Wikipedia

    en.wikipedia.org/wiki/Health_effects_of_radon

    After 11 half-lives (42 days), radon radioactivity is at 1/2 000 of its original level. At this stage, the predominant residual activity is due to the radon decay product 210 Pb, whose half-life (22.3 years) is 2 000 times that of radon, and its descendants 210 Bi and 210 Po, totalling 0.03% of the initial seed activity.
