I think that I have seen similar stories about lead, recovered from older wrecks, being worth considerably more.
I looked up the HMS Natal as I couldn't remember any mention of it at Scapa Flow only the HMS Hampshire, the HMS Natal was sunk in Cromarty not Scapa Flow. I would imagine there would be some infulence from the scanner itself but suspect is would be either negligibleYep, `tis true,the Scapa Flow wrecks have provided uncontaminated steel: as an ex employee of BNFL,(i think I can say this without breaking the Official Secrets Act!). In a plant where radioactive materials were processed, workers like me had to be monitored from time to time to ensure we had not ingested any radioactive material so we routinely went for a chest scan.The room where the scanner was housed was constructed from sections of hull plate cut from HMS Natal, sunk at Scapa, to provide a screened environment so the scanner would not pick up any background readings. I always wondered if the scanner itself would be "contaminated" as it would obviously a modern machine. Bob
Bob,I`m sure about HMS Natal,there were historic photographs of it (afloat) on an information board outside the scanner room for you to peruse as you waited, but i must admit, i must have a crossed line there-Cromarty is nowhere near Scapa Flow for sure.Still, it proves the point that old sunken ships provide uncontaminated steel.Makes you think...............Bob.
