Ultraviolet rays against anthrax. (Digest).

Said to be a proven cleaning agent against biotoxins, the Hand-held Bio Sweeper from Intellicon cleans surfaces of infectious bacteria and spores. The device incorporates a proven UV-C germicidal technology that has been used for a number of years in water and air purification systems, and can be used on electronics, walls, carpets desktops, paper and other non-living materials to detoxify the areas in a matter of seconds. The Bio Sweeper utilises natural ultraviolet light in the shorter UV-C wavelength, which is dangerous for biological materials (UV-A is the light that tans the skin). All bacteria and viruses have their DNA destroyed in a UV-C filter system. Many microbiologists employ UV-C germicidal lamps within engineering control measures to reduce the risk of infection caused by airborne transmission of bacterial pathogens within closed environments. The Bio Sweeper is available in a variety of lamp sized and portable models. Each unit delivers over 20 milliwats/[cm.sup.2] of UV-C, which is over 100 times more energy than needed to kill many common forms of viruses and bacteria, including tough airborne spores -- UV-C has proven effective in killing small pox, dengue and anthrax bacteria.
