Measurements of energetic particle radiation in transit to Mars on the Mars Science Laboratory. Science. 2013 May 31;340(6136):1080-4. http://www.ncbi.nlm.nih.gov/pubmed/23723233 NOTE: The Radiation Assessment Detector, carried on the Mars Science Laboratory, was supported in part by HEOMD at NASA. This article was discussed in numerous press accounts and was highlighted in a "News&Analysis" short article in Science (PubMed 23723213). From that short article: "RAD's bottom line was that a round trip to Mars would give an astronaut a hefty dose of damaging radiation. Zeitlin and colleagues converted RAD measurements of energetic particle abundances, energies, and masses into a measure of biological damage called sieverts, which is related to lifetime cancer risk. During a 360-day round trip, an astronaut would receive a dose of about 662 millisieverts (mSv), according to RAD measurements. National space agencies limit exposure to about 1000 mSv or less during an astronaut's entire career; NASA's limit corresponds to a 3% risk of exposure-induced death from cancer."
