What is Ultraviolet C Light | How effective is UVC on viruses?
The full name of UCV is Ultraviolet C Light Radiation. This is commonly called ultraviolet rays. Ultraviolet light has been used for centuries to kill all kinds of viruses and bacteria. Ultraviolet light is most commonly used to kill bacteria present in a surface or environment.
It was used the most during the Corona period. UVC radiation is used to disinfect air, water and non-porous surfaces. Apart from this, UVC lamps are usually used. UVC lamps are also called germicidal lamps.
What is Ultraviolet C Light
UVC light, that is, UV light, between about 200 and 280 nm wavelength, is high in energy and very effective against viruses, bacteria and fungi. Tests have shown that UV disinfection devices with other UV wavelengths, such as UVA light at 365 nm, are less effective against SARS-CoV-2.
SARS-CoV-2 can be effectively inactivated by UVC irradiation at 254 nm, (How effective is UVC on viruses?) even with high amounts of virus. UVC light has a neutralizing effect, regardless of whether the photons hit the original virus or a new mutation.
Benefits of using a Ultraviolet C Light site for disinfection
- UV-C light does not require any chemicals and toxic compounds.
- Pathogens are unable to build up resistance to UV-C radiation.
- Radiation renders pathogens harmless in seconds.
- The short duration of treatment does not change the properties of a product.
- UV-C light leaves no residue or discoloration on surfaces.
- Ozone does not occur in this range above 240 nanometers.
How effective is UVC on viruses?
It has been proved in many researches that the corona virus can be eliminated through UVC. UVC radiation is also effective in destroying the outer protein coating of the coronavirus, although there are some conditions for this.
If UVC radiation falls directly on such a surface, then bacteria or viruses can be completely destroyed. This light can kill all the germs that usually escape with the use of chemicals.
Viruses such as SARS-CoV-2 typically have only a thin lipid layer that is easily penetrated by UVC light. The photons access the genetic information of the virus, the RNA, and ensure that so-called dimers are formed there.
It works in the RNA of viruses in the same way as it does in the DNA of other germs. Dimers in genetic information make it impossible for germs to reproduce and thus corona viruses, for example, are no longer contagious. This is called “inaction”.
Side Effects of UVC Radiation?
UVC radiation has a bad effect on the human body. If UVC falls directly and closely on any part of the body, then there may be a problem like skin burns. This has been proven in much research, although its side effect depends on the wavelength of the UVC light being used at a place. For your information, let us tell you that UVC is responsible for 80 percent of our skin’s aging, wrinkles and aging spots.
