Radioactivity in the atmosphere has increased over time with the continual
testing of atomic bombs of all types. Steel makers need vast amounts of air
to make steel so it would follow that steel made nowadays contains certain
amounts of radioactivity. Prior to dropping the first A bomb in 1945, steel
was radioactive free, and the only source of this 'clean' steel left lies in
pre 1945 wrecks that lie on the seabed.
