Bonus Fact 2: Tritiated water water containing the tritium isotope of hydrogen is also a form of heavy water.
This type of heavy water is radioactive. It's also much rarer and more expensive. It's created naturally although very infrequently by cosmic rays and can also be produced in nuclear reactors by humans.

Journal of Cellular and Comparative Physiology , 7 (2),
This isotope of hydrogen is called deuterium, and heavy water's more scientific name is deuterium oxide, abbreviated as D 2 0.
With the weight of extra neutrons, heavy-water ice will sink to the bottom of a beaker filled with ordinary H 2 0.
Nuclear power plants harness the energy of countless atoms of uranium splitting apart, or fissioning, in a chain reaction.
Heavy water can help keep such a chain reaction going. As each uranium atom breaks apart, it shoots out neutrons that can go on to split other atoms.
But the neutrons are much more likely to trigger new fission events if they are slowed down. Like traffic cops, heavy water's deuterium atoms effectively curb the pace of neutrons without capturing them.
Nuclear reactors that use heavy water can employ a form of uranium commonly found in nature U rather than requiring so-called enriched uranium, which contains a higher percentage of easily split uranium atoms U but is expensive to produce.
Heavy-water nuclear reactors generate electricity in China above , Canada, and India. No commercial plants in the U. In its natural state, common uranium U can't generate destructive nuclear explosions.
It either must be enriched—made more concentrated in a rare form of uranium U —or converted into plutonium Pu Heavy water can play a role in breeding weapons-grade plutonium from common uranium.
In a heavy-water nuclear reactor, when neutrons bombard U, some uranium atoms absorb an additional neutron and are transformed into Pu On the eve of World War II, scientists both in Germany and Great Britain realized that heavy water could be used in this way to make nuclear weapons.
And because this potential still exists today, the International Atomic Energy Agency and various national governments monitor the production and distribution of heavy water.
Heavy water provides a path to turn common uranium into plutonium, one of the easily split or "fissile" materials that fuels nuclear bombs.
When Norsk Hydro began producing heavy water in , Norway became the first country with a commercial heavy-water plant. The Nazi invasion of Norway in transferred control of the plant—and most of the world's heavy water—to Germany.
One critical system affected by this change is mitosis, the cellular division used by the body to repair and multiply cells. Too much heavy water in cells disrupts the ability of mitotic spindles to equally separate dividing cells.
Other species tolerate heavy water better. Since only about one water molecule in 20 million naturally contains deuterium—which adds up to about five grams of natural heavy water in your body and is harmless—you don't really need to worry about heavy water poisoning.
Even if you did drink some heavy water, you'd still be getting regular water from food. In addition, the deuterium wouldn't instantly replace every molecule of ordinary water in your body.
You'd need to drink heavy water for several days to see a negative result, so as long as you don't do it longterm, it's okay to drink.
Bonus Fact 1: If you did drink too much heavy water, even though heavy water is not radioactive, your symptoms would mimic radiation poisoning.
This is because both radiation and heavy water damage the ability of cells to repair their DNA and replicate. Bonus Fact 2: Tritiated water water containing the tritium isotope of hydrogen is also a form of heavy water.
This type of heavy water is radioactive. It's also much rarer and more expensive. Here's how it works. However, because of the high turnover rate of water, drinking a small amount of the substance causes no ill effects.
In fact, American physicist Harold Urey once drank heavy water to learn whether it tasted different from ordinary water in the name of science, of course.
