Annual solar UV exposure and biological effective dose rates on the Martian surface

摘要: The ultraviolet (UV) environment of Mars has been investigated to gain an understanding the variation exposure throughout a Martian year, and link this flux biological effects possible survival organisms at surface. To idea how solar UV radiation varies between different regions, including planned landing sites two future surface missions, we modelled total one year for dust scenarios. understand degree stress on micro-organisms and/or molecules essential life Mars, also calculated biologically effective dose (BED) T7 Uracil in relevant wavelength regions as function season latitude, discuss rates presence radiation. High T7/Uracil BED ratios indicate that even high latitudes where is significantly reduced, still hostile due persisting UV-C component flux.
