   you stated "Don't need to bury it",  now you say you do.

   your number is wrong, try 700 mSv   
      
   ...  assuming *no solar flares* dumbass, Solar Particle Event (SPE) the   
   astronauts should expect one SPE every two months on average   
      
   no Mars magnetic field to deflect, no atmosphere to attenuate.
