IUVA – UV 101: Overview of Ultraviolet Disinfection

“UV-C & UV-B light has a direct disinfection effect when its energy is absorbed by genetic material (limiting replication) or by other cellular or viral components such as a proteins (limiting attachment and infectivity). UV-B and UV-C photons can directly alter chemical bonds within these key biomolecules, affecting their structure and function. Where photons are absorbed by DNA/RNA the resulting damage can inhibit the microorganism’s ability to replicate, rendering it no longer infectious (Harm 1980).”
