Europe's worst drought in years has pushed the mighty river Danube to one of its lowest levels in almost a century, exposing the hulks of dozens of explosives-laden German warships sunk during World War II.
The vessels were among hundreds scuttled along the Danube by Nazi Germany's Black Sea fleet in 1944 as they retreated from advancing Soviet forces, and still hamper river traffic during low water levels.
this is the basics for it but the air they use to forge new steel also plays a part in it and can lead to limited contamination . water is also one of if not the best shielding agents for radiation
Low-background steel is any steel produced prior to the detonation of the first nuclear bombs in the 1940s and 1950s. Typically sourced from shipwrecks and other steel artifacts of this era, it is often used for modern particle detectors because more modern steel is contaminated with traces of nuclear fallout.[1] Since the cessation of atmospheric nuclear testing, background radiation has decreased to very near natural levels,[2] making special low-background steel no longer necessary for most radiation-sensitive applications, as brand-new steel now has a low enough radioactive signature that it can generally be used in such applications.[3] However, some demand remains for the most radiation-sensitive applications, such as Geiger counters and sensing equipment aboard spacecraft, and World War II-era shipwrecks near in the Java Sea and western South China Sea are often illegally scavenged for low-background steel.[4]
I'm not convinced that is still true, though it might have been true in the 1960s. Who exactly will buy it and how much will they pay for it today? Supporting links? I searched and only found stories about how it used to be wanted, but no concrete information that it still is in demand like it was in the past.

Molten steel will absorb atmospheric radiation, any steel forged before the first atomic tests is worth far more than modern steel.
It was decades ago, is it still? Recent examples?
Generally it's used for shielding and other scientific purposes.
Sorry, the market for old steel is now pretty much sunk. Reduced radioactive dust plus sophisticated instrumentation that corrects for background radiation means new steel can now be used in most cases.
