No telling what they would have gotten from duct tape ![Cheesy :D](//www.nukeworker.com/forum/Smileys/new/cheesy.gif)
I'd imagine not much...the scotch tape effect depends in part on the corona effect on the tape material....which is what allows the formation of the plasma, and thus x-rays, during the rapid peeling.
Actually, instead of a poor man's X-ray tomography device, where this could come in handy is a low-power stealth communication system. would have to be low power, and only a few characters, like a decoder ring, pull the strip to generate plasma, run it through what would look like a tiny lighting arrestor in reverse....voila, one shot hard-to-find covert comms on a frequency band not currently being monitored by cryptologists, and too weak(probably) to be found by ELINT birds. I better hurry and file my patent.....
