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.
包括前往火星的星际任务，将使宇航员置身于极端辐射环境中。寻找降低辐射诱发癌症风险的方法是火星任务筹备工作的重中之重。其中一个选择是设计生命支持系统，该系统能生成稳定氢同位素（氘）含量低的水供宇航员饮用。初步研究表明，将氘含量降低65%确实能赋予水一定的抗癌特性。因此，饮用无氘水有可能降低火星宇航员因极端辐射暴露而患癌症的风险。
