Researchers are producing X-Rays by Pulling Scotch-Tape from it's roll, that's contained in a Vacuum Chamber.
They claim it was substantial enough for one researcher to image his finger.
I would suppose it would be possible to build a inexpensive wind-up or human powered X-Ray Machine. My hope is that it would be strong enough for X-raying Welds.
I've always wanted a pair of those X-Ray Glasses you'd see in the back of Comic Books.
