Nah, they don’t use low-rad steel for medical implants. Mostly for scientific instruments that would thrown off by even a small rise in background radiation. I

Nah, they don’t use low-rad steel for medical implants. Mostly for scientific instruments that would thrown off by even a small rise in background radiation. IIRC the bulk of the supply came from the scuttled German fleet at Scapa Flow, where the ships involved were not graves - they were intentionally scuttled by the crew, who got off and were rescued.
