Does ultra-violet radiation kill bacteria and viruses?

Yes, but it has to be the right uv frequency. UV-C is the frequency used for this purpose. You will find these bulbs used in furnaces ducts, toothbrush holders, air cleaners, and water filtration systems. It does a good job in these areas, just check Ebay they have many of these systems for sale. The bulbs typically are left on all the time and last one year.

Does ultra-violet radiation kill bacteria and viruses?
Yes , It does , the reason is that Disinfection of water generally uses low pressure mercury vapor lamps to generate ultraviolet radiation. These lamps generate short wave ultraviolet in the electromagnetic spectrum region of about 254 nanometers. Light in this region is lethal to micro-organisms including bacteria, protozoa, viruses, molds, yeasts, nematode eggs and algae.
Reply:yes, UV light is sometimes use to kill bacterias (not sure about viruses since viruses needs to be in a host to be active-if not they are functionless).



I know this becuause my fellow bio classmate use UV light as an antibacterial agent for her senior thesis.
