Scotch Tape generates X-Rays

Apparently it is a known fact for quite sometime - but it's news to me - that unpeeling scotch tape generates light and X-Rays.

What they didn't know was that those X-Rays are more powerful than they expected. Some researchers at UCLA have shown that regular scotch tape can be used to x-ray the bones in the human body.

This kind of energy release — known as triboluminescence and seen in the form of light — occurs whenever a solid (often a crystal) is crushed, rubbed or scratched. It is a long-known, if somewhat mysterious, phenomenon, seen by Francis Bacon in 1605. He noticed that scratching a lump of sugar caused it to give off light.

The leading explanation posits that when a crystal is crushed or split, the process separates opposite charges. When these charges are neutralized, they release a burst of energy in the form of light.

However, before you start worrying about going to your office dressed in a protective lead outfit or throwing out all scotch tapes out the window, keep in mind this only happens when the scoth tape is in a vacuum... or so they say...
