| | Water containing deuterium, a heavy isotope of hydrogen.
- (D2O) Water containing significantly more than the natural
proportions (one in 6,500) of heavy hydrogen (deuterium, D) atoms to ordinary
hydrogen atoms. Heavy water is used as a moderator in some reactors because it
slows down neutrons effectively and also has a low probability of absorption
of neutrons.
