Certain wave lengths of UV light are harmful to living tissue because it
causes nicks in the DNA, whether or not this kills the orgainism or causes
mutations is really based upon the lenth of exposure and the intensity.
Molecular genetic technics use UV to make DNA bands glow orange when
exposed along with other chemicals and the DNA is still viable. UV shold
not be used to sterilize or kill bacteria or viruses. Gamma radiation or
heat and pressure in an autoclave for accepted lengths of time is the only
sure meathods
