Deuterium depleted water may be put to its most noble use until now, as the water for cosmonauts. Because radiations in space are higher, deuterium depleted water may be the simple solution to reduce the impact of the cosmic radioation on the bodies of the cosmonauts.
DEUTERIUM DEPLETED WATER IN SPACE
”Interplanetary missions, including to Mars, will put crews into severe radiation conditions. Search for methods of reducing the risk of radiation-induced cancer is of the top priority in preparation for the mission to Mars. One of the options is designing life support systems that will generate water with low content of the stable hydrogen isotope (deuterium) to be consumed by crewmembers. Preliminary investigations have shown that a decrease of the deuterium fraction by 65% does impart to water certain anti-cancer properties. Therefore, drinking deuterium-free water has the potential to reduce the risk of cancer consequent to the extreme radiation exposure of the Martian crew.” says science.gov
