I am sure it has changed by now but when I had a PET scan, a few years ago, the technician was using rolling screens they walked behind coated with gold I was told.

Thanks for such a rapid response. So, since the reactions take place where there is more uptake there is most likely a canceling out with positron and the spare electron. I didn’t know about the decay that produces Oxygen. The reason I asked this was that I had a PET scan a couple of years...

I understand that a PET scan will produce Positrons which will come into contact with an electron and produce Gamma rays in the area where there is a high uptake of sugar (assume glucose). In this process of annihilating an electron, some poor atom will lose an electron which I assume would...
