He had no idea how it got there. I had a relative who was a doctor, he had xray equipment aa a kid I was staying there and asked if I could make an x-ray from my hand. He objected first, told me too much xray radiation was harmfull, but then let me xray my hand once and look at it at a big scintilation screen. normally it would be used to x-ray people. My hands still work and have not fallen off yet. So anyways, be careful with the amount of radiation when experimenting.
