   A quick back-of-envelope calculation says that an hour is lots of time to   
   get through the inner belt, which is the really nasty area.  They probably   
   were within the outer belt at LM jettison time, but that's much less of a   
   concern.   
      
   The total Apollo 13 crew radiation dose was actually quite low.  (Apollo   
   doses were all over the map, probably because of different paths through   
   the belts and random variations in solar activity.  Apollo 14 was in fact   
   the highest.)
