How does Ultraviolet Disinfection work?

By Florian Auckenthaler | on March 9, 2014

For room and surface disinfection, CSGIm uses the IRS 1140m, a mobile Intelligent Room Sterilization™ system that employs UV-C light to eliminate microbial reservoirs in the environment. UV-C causes damage to nucleic acid of microorganisms by forming covalent dimers between nucleic bases in DNA and RNA (Kowalski et al. 2009). The formation of such bonds prevents the genetic material from being unzipped for replication, rendering the organism unable to reproduce. UV-C is laboratory proven to kill Clostridium difficile, MRSA, VRE, and other nosocomial causing microorganisms; there are no known bacteria or viruses immune to UV-C (U.S. EPA, 1999).
