AB  - In this study, results are presented from the on-board radiation assessment 
      detector (RAD) of Mars Science Laboratory (MSL). RAD is designed to measure the 
      energetic particle radiation environment, which consists of galactic cosmic rays 
      (GCRs) and solar energetic particles (SEPs) as well as secondary particles 
      created by nuclear interactions of primary particles in the shielding (during 
      cruise) or Martian soil and atmosphere (surface measurements). During the cruise, 
      RAD collected data on space radiation from inside the craft, thus allowing for a 
      reasonable estimation of what a human crew travelling to/from Mars might be 
      exposed to. On the surface of Mars, RAD is shielded by the atmosphere (from 
      above) and the planet itself (from below). RAD measures the first detailed 
      radiation data from the surface of another planet, and they are highly relevant 
      for planning future crewed missions. The results for radiation dose and dose 
      equivalent (a quantity most directly related to human health risk) are presented 
      during the cruise phase, as well as on the Martian surface. Dose and dose 
      equivalent are dominated by the continuous GCR radiation, but several SEP events 
      were also detected and are discussed here.
