Scotch Tape: First It Defrosts Glass Now It Emits X-Rays

From NewScientist:

Peeling ordinary sticky tape can generate bursts of X-rays intense enough to produce an image of the bones in your fingers.

Seth Putterman and colleagues from the University of California, Los Angeles used a motor to unwind a roll of sticky tape and recorded the electromagnetic emissions. Ripping the tape from its roll at 3 centimetres per second generated X-ray bursts of 15 kiloelectronvolts - each lasting one-billionth of a second, and containing over a million photons.

Putterman admits he is not sure exactly what is going on. "My attitude is to marvel at the phenomenon - all we are doing is peeling tape, and nature sets up a process that gives you nanosecond X-ray bursts."
