Comparison of Some Radiation Exposures to Mars-Trip Level

This graphic compares the radiation dose equivalent for several types of experiences, including a calculation for a trip from Earth to Mars based on measurements made by the RAD instrument shielded inside NASA Mars Science Laboratory spacecraft.
