ULTRAVIOLET GERMICIDAL IRRADIATION (UVGI)

ULTRAVIOLET GERMICIDAL IRRADIATION (UVGI)

Ultraviolet germicidal irradiation (UVGI) is a Disinfection method using short wavelength UV light to kill or inactivate micro-organism by disrupting their DNA , leaving unable to perform vital cellular function.
UVGI is the use of ultraviolet energy (electromagnetic radiation with a wavelength shorter than of visible light) to kill or inactivate microbes(viral, bacterial, and fungal species).UVGI term is used for surface and airborne microorganisms killing. UV-C doses may not cause immediate micro-organism death but the micro-organism may be “deactivated”.UV-C deactivate the DNA of micro-organism.Some micro-organism function may still exist but replication of micro-organism is impossible. so it soon dies.Continuously UV dosing over period of time ,result showing cell death.UV-C electromagnetic energy deactivates a microorganism nucleus or DNA @ 254nm.So replication of micro-organism is impossible and results cell death.
