I'd just like to stress something here with regard to UV-C, just in case someone's actually considering this route (like, say, me). UV-C is
dangerous. It's not radioactive-give-you-cancer-make-you-sterile dangerous or anything, but this is not particularly nice stuff. It actually isn't all that much of a cancer risk (won't penetrate dead layers of skin), but I'd do my best to avoid letting any of the stuff reach your eyes unless you prefer to savor that "just watched an arc welder" feeling.
