  2. Heavy water - Wikipedia

    en.wikipedia.org/wiki/Heavy_water

    Since one in about every 6,400 hydrogen atoms is deuterium, a 50-kilogram (110 lb) human containing 32 kilograms (71 lb) of body water would normally contain enough deuterium (about 1.1 grams or 0.039 ounces) to make 5.5 grams (0.19 oz) of pure heavy water, so roughly this dose is required to double the amount of deuterium in the body.

  3. Global meteoric water line - Wikipedia

    en.wikipedia.org/wiki/Global_meteoric_water_line

    Global meteoric water line. Data are global annual average 18 O and 2 H values from precipitation monitored at IAEA network stations distributed globally (n=420). [1]The Global Meteoric Water Line (GMWL) describes the global annual average relationship between hydrogen and oxygen isotope (oxygen-18 [18 O] and deuterium [2 H]) ratios in natural meteoric waters.

  4. Deuterium - Wikipedia

    en.wikipedia.org/wiki/Deuterium

    Simplified chart of particle content. Deuterium occurs in trace amounts naturally as deuterium gas (2 H 2 or D 2), but most deuterium atoms in the Universe are bonded with 1 H to form a gas called hydrogen deuteride (HD or 1 H 2 H). [12] Similarly, natural water contains deuterated molecules, almost all as semiheavy water HDO with only one ...

  7. Deuterium-depleted water - Wikipedia

    en.wikipedia.org/wiki/Deuterium-depleted_water

    Deuterium-depleted water has less deuterium (2 H) than occurs in nature at sea level. [1] Deuterium is a naturally-occurring, stable (non-radioactive) isotope of hydrogen with a nucleus consisting of one proton and one neutron. A nucleus of normal hydrogen (protium, 1 H) consists of one proton only, and no neutron.

  9. Saylorville Lake - Wikipedia

    en.wikipedia.org/wiki/Saylorville_Lake

    At its normal level of 836 feet (255 m) above sea level, Saylorville Lake covers an area of 5,950 acres (24 km 2) or 9.3 square miles (24.1 km 2) and reaches some 17 miles (27 km) upstream. At full flood stage the lake can reach 16,700 acres (68 km 2 ) or 26.1 square miles (67.6 km 2 ) and reach 54 miles (87 km) long.
