When you crunch bones....
Until I was in my early 20's I had been lucky and not broken many of my bones, but then I discovered I really wasn't quite as supple as in the past, I wouldn't bounce, and therefore snapped a few bones, and my back.

Now, I am NHS, whenever I was xrayed they would keep the xrays, for storage but also to reclaim the silver, is this even possible? How do you reclaim a silver salt (silver nitrate) from cellulose?

On another note, I nearly shagged a dwarf.

I found an X-ray of a foot in the hospital car park
I'm saving it to use as evidence when I need an emergency sickie.

with chemistry (almost) anything is possible.

It's probably metallic silver
embedded in a gelatine matrix.

I'd imagine recovery involves something like stripping the gelatine from the cellulose using hot alkali, then adding nitric acid to form silver nitrate, which can then be precipitated as silver chloride or something by addition of a suitable salt.

Then recover the solid precipitate by filtration, and reduce to metallic silver somehow, Formaldehyde, citric acid or ascorbic acid might do. I'm not sure. Silver refining is big business and processes are guarded fiercely.

But to an industrial chemist - and I'm not one - the process is a piece of piss (albeit a tightly controlled one!)

sounds alright to me
but how much would you actually get out of an x-ray?

probably sod all for one
but if you were to multiply that by the millions that were taken annually it adds up to a sum worth getting out of bed for.
