Perchlorate Radiolysis on Mars and the Origin of Martian Soil Reactivity |pdf=|usr=}}{{23746165}} gab.com Text Perchlorate Radiolysis on Mars and the Origin of Martian Soil Reactivity JO: Astrobiology http://www.kidney.de/pget.php?&tw=1&pmid=23746165 #FOAvip Results from the Viking biology experiments indicate the presence of reactive oxidants in martian soils that have previously been attributed to peroxide and superoxide. Instruments on the Mars Phoenix Lander and the Mars Science Laboratory detected perchlorate in martian soil, which is nonreactive under the conditions of the Viking biology experiments. We show that calcium perchlorate exposed to gamma rays decomposes in a CO2 atmosphere to form hypochlorite (ClO?), trapped oxygen (O2), and chlorine dioxide (ClO2). Our results show that the release of trapped O2 (g) from radiation-damaged perchlorate salts and the reaction of ClO? with amino acids that were added to the martian soils can explain the results of the Viking biology experiments. We conclude that neither hydrogen peroxide nor superoxide is required to explain the results of the Viking biology experiments.
