What is UV-C?
UV light spans the electromagnetic spectrum between 100 and 400 nm, with photon energies ranging from 3 to 124 eV. UV-A (400 to 315 nm), UV-B (315 to 280 nm), very high energy and destructive UV-C (280 to 200 nm), and vacuum UV are the four wavelengths in the UV sector (200 to 100 nm).
UVC has been shown to have germicidal (or germ-killing) properties. The electromagnetic waveform of 253.7 nm is efficiently absorbed by DNA and RNA (the genetic code for all lifeforms), altering their structure. This damage prevents the damaged cells from reproducing, which means they can no longer infect and are no longer harmful.
