Far UV-C radiation: An emerging tool for pandemic control

Far UV-C, informally defined as electromagnetic radiation with wavelengths between 200 and 230 nm, has characteristics that are well-suited to control of airborne pathogens. Specifically, UV-C been shown be highly effective for inactivation pathogens; yet this same minimal potential cause damage human skin eye tissues. Critically, unlike UV-B, does not substantially penetrate the dead cell layer (stratum corneum) reach germinative cells in basal layer. Similarly, through corneal epithelium eye, thereby preventing exposure within eye. The most common source is krypton chloride excimer (KrCl*) lamp, which a primary emission centered at 222 nm. Ozone production from KrCl* lamps modest, such indoor ozone these systems can accomplished easily using conventional ventilation systems. This set offers devices used occupied spaces, allowing improved effectiveness pathogens, including those responsible COVID-19.
