Post 1945 steel vs pre-1945 steel
(OP)
Gentlemen;
Pardon the arcane question, but I'd like to get input from the experts on this one:
http://uboat.net/fates/deadlight_news.htm
The article indicates (and I've heard) that steel manufactured after the atomic age began in July 1945 contains certain contaminates. These are evidently in the atmosphere, and were put there by the various nuclear tests. Steel manufactured before July 1945 (such as the sunken warships) is apparently free of this contamination, and has certain industrial applications.
Since it's probably very expensive to raise sunken warships just for the steel, I gather that there's some truth to this.
Now, initially I thought this whole concept was a load of BS. Is the pre-atomic steel issue really a valid one?

The types of radiactive isotopes did change after 45. You could make 'clean' steel today by starting with ore and not using any scrap.
Even using scrap today the levels of radiation are so low that typical steel from the US can be used to amke sensitive X-ray and photographic equipment.
