How Effective is Far-UVC Light in Preventing the Spread of
Coronaviruses?
In light of the massive surge of COVID-19, every corner in the world
is threatened by its harmful effects. Numerous methods can be done
to effectively destroy and prevent its transmission, and one of the
most reliable ways is the use of Far-UVC Light. It has a powerful
wavelength range of ultraviolet disinfection that is divided into 4
bands.
Ultraviolet rays have high energy that can destroy the DNA and RNA
structure of microorganisms and cause them to break, crosslink, or
form photochemical products. This basically kills the ability of
viruses and bacteria to harm furthermore.
Diving into it more specifically, ultraviolet rays act on oxygen
atoms in cells to form lethal active oxygen-free radicals, which can
cause microbial cells to fail to proliferate or directly die. More
so, with a wavelength of about 185 nm, they are able to produce
ozone in the air that has a strong oxidizing effect of killing
viruses and bacteria.
To sum up, ultraviolet rays can use their own energy to destroy the
structure of various microorganisms, generate ozone in the air, and
utilize that to kill them.
With what we are currently facing, the use of ultraviolet rays is a
proven weapon in fighting this virus, specifically, COVID 19. Its
genetic material, which is the RNA, can be effectively killed,
thereby no longer having the ability to synthesize its required
protein to transmit its deadly reaction.
