If you want to make your own x-rays, look for a book called "The Amateur Scientist" by C.L. Stong. This is a book of reprints of the old "Scientific American" "Amateur Scientist" columns. It was printed in the early sixties. In one of the articles, Stong shows you how to make an x-ray emitter out of a diode vacuum tube. The tube used would probably be hard to find nowadays, but the information in the article should help you find a substitute. Other articles let you build an atom smasher (a small linear accelerator powered by a van degraff generator) and a working microscope, which is made from a glass rod melted in the flame from a kitchen stove. It's the same type of microscope van lewuenhook(spelling) used. I built one when I was in high school and it works! You can see microbes with it. Just think, with one book, you can find microbes, mutate them and then see what kind of damage they do to your innards! And the X-ray source might erase your OTP PIC chips! Dave Mullenix
