And the chinese are looting wwii ship wrecks to get that steel.
Chinese ship accused of looting iconic WWII shipwrecks
An illegal Chinese salvage operation is suspected to have raided two iconic World War II wrecks.www.marinecorpstimes.com
Not just the Chinese. WWI wrecks from the battle of Jutland have been salvaged for decades even though they are war graves. And this is not in the boonies, this is in busy European waters.
Battle of Jutland war graves 'vandalised' by illegal metal scavengers
Ministry of Defence urged to take action amid fears that the recently discovered wreck of HMS Warrior will be pillaged
Up until recently, the Kaiser's WWI fleet scuttled at Scapa Flow was still being salvage for pre-1945 steel.
The contamination came from the forced air that went into smelting and processing the steel in the first place, which had higher background radioactivity.
im talking about low background that was then used to make something. it can get contaminated

I would suspect 15 tons or so would get one in.

There was a time it got contaminated real fast. Now, less.

So random old industrial factory shit would solidly qualify.

Not if it's been exposed to air for an extended period.

I thought it just had to be smelted pre-radiation?
I believe the blanket of water is what preserves the steel's dolphin-safe street cred.

Doesn't work like that.
The concern here is radioactive particles - picture it like dust. These float through the air, precipitate out on things, etc. They can be absorbed into a large thing via certain biologic or chemical processes, but in general will just settle on surfaces and can be easily cleaned off just like dust. This is why radiation workers commonly wear tyvex suits, why poly bags are used for radcon work, etc. - easy to clean contamination off if any gets on. Same thing for a tractor or other iron object - contamination may settle on the surface, and could be caught under paint, become trapped in rust, etc., but isn't going to contaminate the bulk material. However, when the metal is molten contamination becomes dissolved into the material and is essentially impossible to remove.
Bottom line, with adequate preparation anything smelted/cast pre 1945 should be low background provided it hasn't been welded on or otherwise heated to high temperatures. Problem of course is that by the time you go through all the trouble to prep it it's not worth the effort for small amounts, and the need to segregate from normal steel is another can of worms. Plus if someone screws up and it's actually not pre war you could contaminate large amounts of low background metal.
Seems to be a decreasing demand though, as background is now pretty much back down to pre 1945 levels.

Doesn't look too implody to me but I don't know shit about fuck.

I think that's the tail section what wasn't pressurized.

Yeah, plus look at the shell, looks like it imploded forward of that and the ass end opened up like clam shell.

I mean, if it was made of something bendy, sure.
Looks like that's just part of the fairing.

That's some sort of fairing, likely part of the aft end section. Fully expect what they recovered is a couple sections like that which were free flood, probably with significant damage but still recognizable and both end bells, with the composite cylindrical section being essentially dust now.

waiting for someone to build a replica and send it up and down until it implodes and make a documentary of it.
Shit, that's not a bad idea.

The only person stupid enough to build one of those things (a 61 year old white guy, BTW) has probly already been consumed as part of someones fish and chips.

That's the tail cone that just existed to make the equipment underneath a little more hydrodynamic. It wasn't under pressure, it was flooded.Doesn't look too implody to me but I don't know shit about fuck.
The black ball inside I'm pretty sure is what should have been 15' long and full of people...instead it went all foil ball and crushed and extruded people parts in a 50th of a second.

A new action adventure movie, but instead of slowly drowning or running out of air, it’s a premature ejaculation climax over in a split second. The end

There better be damn good previews or I want my money back from the theater!
