The entire UV spectrum can kill or inactivate many microorga-
nism species, preventing them from replicating. UVC energy
at 253.7 nanometers provides the most germicidal effect.
The application of UVC energy to inactivate microorganisms is
also known as Germicidal Irradiation or UVGI. nisms.
UVC exposure inactivates microbial organisms such as bacteria and viruses by altering the
structure and the molecular bonds of their DNA (Deoxyribonucleic acid). After UVC exposure,
the organism dies off leaving no offspring, and the population of the microorganism dimini-
shes rapidly.
Ultraviolet germicidal lamps provide a much more powerful and concentrated effect of
ultraviolet energy than can be found naturally. Germicidal UV provides a highly effective
method of destroying microorganisms.
10. What is Ultraviolet?
Ultraviolet (UV) light is one form of electromagnetic energy produced naturally by the sun.
UV is a spectrum of light just below the visible light and it is split into four distinct spectral
areas – Vacuum UV or UVV (100 to 200 nm), UVC (200 to 280 nm), UVB (280 to 315 nm)
and UVA (315 to 400 nm).
