   Indeed they would.  It would be *less* of an issue outside the shelter,   
   because only the cosmic rays coming from the far side of the shelter would   
   be an issue, whereas inside the shelter you're getting it from all sides.   
   But it would be preferable to locate the shelter away from normal sleeping   
   and working quarters.
