[ RadSafe ] Low background Shielding Material

I have heard many times that "Pre World War II battleship steel" is used
for extremely low background shielding.  I had always wondered about
that as it seemed that an infinitesimal amount of fallout would find its
way into steel.  But then I heard another explanation that made more
sense something to do with the fabrication process that apparently
changed post WWII and involved a small amount of Co-60 I think.

Does anybody out there know what the explanation is?
