"Unwinding household sticky tape in a vacuum emits radiation strong enough to X-ray a human figure, according to a new study in the British journal Nature.
"As the tape peels, a charge builds between the opposite charges of the sticky adhesive and the tape and creates an electric field. At reduced pressure in a vacuum, this accelerates electrons on the adhesive to very high speeds and when they whack into the positively-charged tape roll, X-rays result. The pulses last for a billionth of a second, with an intensity of 100 milliwatts."
"It could be possible to create inexpensive x-ray machines for third world countries where electricity is expensive [me: like Cambodia!]," said [UCLA researcher Juan] Escobar."
