UV devices do not detect radioactivity. They are probably used to identify special marks on the bills to prevent counterfits. UV's are the "black lights" type of bulb.
Rumors are flying again that Arafat, the undead, is dead again, they think........
That was my thinking as well. UV can, however, kill some biohazards. Question: is the UV used for counterfeit detection strong enough to kill the little germies?
I didn't mean to imply that the UV would detect any sort of nuclear radiation ...the UV gadgets just detect the spectrum of hidden lines of color woven into the currency...each denomination having it's own color code and location. As one hypersensitive to UV light it peaked my curiosity when one was placed in the local pharmacy.
