   Apollo couldn't spare any mass for actual shielding.  The Command Module   
   heatshield and the equipment covering its walls provided a fair bit of   
   natural shielding, as did the Service Module attached behind it, and that   
   was deemed sufficient.  This was ultimately confirmed by radiation   
   instruments carried on some of the unmanned Apollo tests.
