Flight to Mars to cut cosmonauts’ lifespan by 2.5 years, says report. Cosmonauts will use special water during long space missions

The space radiation effect during an inter-planetary flight to the Red Planet will reduce the cosmonauts’ lifespan by 2.5 years, according to the materials released at the 17th conference on space biology and medicine in Moscow on Monday. "For a two-year length of the expedition’s flight to Mars and back, the aggregate radiation risk during the cosmonauts’ lifespan irrespective of their age under the RR [radiation risk] protection of 20 g/sq. cm will measure 7.5%, while the average upcoming lifespan will decrease by 2.5 years," the report says. Also, the aggregate radiation risk throughout the cosmonauts’ career after the inter-planetary flight and the preliminary four orbital half-yearly flights (or two-year flights) will equal about 12%, which is somewhat higher than the 10% risk level throughout the cosmonauts’ career for orbital flights in Russia existing today and approved by Russia’s State Space Corporation Roscosmos and the Federal Agency for Medical, Biological and Extreme Problems (Medbioextrem).
"Drinking water with new functional properties will hold special place in the system of increasing cosmonauts’ resistibility to radiation. Of great interest is light isotope water and water with controlled and optimized mineral composition," the conference’s report says. Special attention must be paid to preventing water preservatives, including silver ions, from getting into the cosmonaut’s body. Silver is a heavy metal, and heavy metals increase the harmful effects of ionizing radiation. Also, scientists suggest cosmonauts should sleep in special water-filled bags. "For instance, one might consider the feasibility of using sleeping bags filled with water mixed with gel or polyethylene granules. Water and polyethylene contain light elements, including hydrogen. Both provide effective protection from neutrons, both primary and secondary ones," the report says.
