UVGI has been used as an accepted method of disinfection since the mid-20th century, primarily in medical sterilization applications. The Many Uses of UVC Surface Sterilization ![]() UV light ranges from 10 nm (vacuum and extreme UV) to 400 nm, divided mostly into UVA (315-400 nm), UVB (280-315 nm) and UVC (100-280 nm), with UVC being the most effective at sterilization with germicidal properties. Ultraviolet light emitted from the sun is not visible to the human eye as it has a higher frequency, thus a shorter wavelength, than visible light. Germicidal lamps for disinfection purposes are designed differently than standard fluorescent lamps, engineered to emit wavelengths in the UVC range. Using ultraviolet (UV) light to sterilize surfaces is also called ultraviolet germicidal irradiation, UVGI, and is a method of disinfection proven to be highly effective when administered with adequate dosing from quality UV lamps. Viruses tend to live longer on surfaces that are stainless steel, plastic or similarly hard, nonporous surfaces as opposed to softer surfaces such as fabrics. ![]() As documented in the Technical Report, 2020 COVID-19 Coronavirus Ultraviolet Susceptibility, the SARS-CoV-2 virus that causes the COVID-19 respiratory disease is expected to live on surfaces anywhere from 6 hours to 9 days. UVC Lamps Provide Surface SterilizationĬold and flu viruses can remain infectious on surfaces for several hours or even days, depending on the surface, the temperature and humidity of the environment and the amount of virus deposited on the surface. ![]() UV light is proven to provide effective surface sterilization, eliminating even drug-resistant superbugs and novel coronaviruses with high efficacy. Infectious diseases are spread through contaminated surfaces with some bacteria and viruses living for days on nonporous surfaces.
