Folder: SF. Civil Defense. Newscopy: "If an atom bomb should drop on an American city, there WOULD be a defense--not against the bomb, but against its deadly after effects. That defense is being prepared right here in San Francisco, in a hitherto highly secret research program at San Francisco Naval Shipyard, where purple tags marked "DANGER--RADIOACTIVE" warn the curious from the nation's only atomic defense laboratory."
