Ultraviolet (UV) light is a short wavelength light invisible to the human eye. Lights in our homes and outdoors are a longer wavelength light while X-rays are a shorter wavelength light. UVC falls between the two.
The sun puts out three different types of ultraviolet light: UVA light, UVB light and UVC light.
The first two are let into the atmosphere in various intensities. UVC light is almost completely absorbed by the earth's ozone layer, but it's powerful not the less.
It was discovered in 1800C that UVC light can be used as a UV light Sanitizer with the ability to kill up to 99.9% of germs.
Generation of UV C light with a wavelength of 253.7 nm can sanitize by penetrating the thin wall of a small microscopic organism and destroying its nucleic acids
This disrupts the DNA structure, destroys the cross-linking Structure between DNA / RNA and protein substance, lets microorganisms (cells, bacteria, viruses, fungi, etc.), and either kills It or renders it unable to reproduce
How long the virus stays on different surfaces.
