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.
