Luckily radiation levels have pretty much dropped back to pre-war levels now so new steel can be low-background as well. It was possible to make new low-background steel from 1945 onward too it just would have been more expensive than salvaging pre-war ships. I like the analogy though, it fits.
Isn’t it the same with the upper atmosphere and humans more or less. I remember something about radio active tracker used which wouldn’t be present if it were for nuclear testing etc.
