> Low radiation steel is less needed because new steel is lower radiation. The atmospheric radiation level has dropped and steel making uses oxygen instead of air.

> Presumably there are uses that need old steel but they are probably smaller amounts.

This comment seems out of place? It would have made sense as a reply to a different comment thread in a different article a couple weeks ago: https://news.ycombinator.com/item?id=41323780 but I don't get how/why it ended up here. No one was talking about steel at all, as far as I can see?

edit: oh, there's another article today where folks are talking about low-background steel. I assume this comment was just supposed to go there. https://news.ycombinator.com/item?id=41436009
