This is amazing.  X-rays from ordinary adhesive tape.  The cool thing is they expect to be able to come up with a way to make an inexpensive, low-power x-ray machine for use in poor areas or areas without reliable power.  This would be an interesting project for Seattle University's Engineers Without Borders program

It turns out that if you peel the popular adhesive tape off its roll in a vacuum chamber, it emits X-rays. The researchers even made an X-ray image of one of their fingers.

Who knew? Actually, more than 50 years ago, some Russian scientists reported evidence of X-rays from peeling sticky tape off glass. But the new work demonstrates that you can get a lot of X-rays, a study co-author says.
