???? Yes if you peel scotch tape in a vacuum it emits x-rays that are powerful enough to actually use with x-ray film. A couple of scientists in California discovered this and even took an x-ray of their finger to prove it. They say that it’s safe to use tape in your office because the radiation doesn’t happen in the presence of air, but if you need to fix a vacuum chamber with scotch tape you need to be careful.
This is a short clip of the machine they built in action.
