UV lights can kill many kinds of germs and viruses. Ultraviolet light has more energy than visible light and radio waves but less energy than gamma rays or X-rays. The sun emits UV radiation, and other sources include man-made instruments such as UV lights and tanning beds. Research supports the use of UV radiation to kill viruses and bacteria such as SARS-CoV-2, which causes COVID-19. Therefore, contact Hutchinson today if you need UV treatment in Cherry Hill, NJ!
Types of UV Light
UV light is classified by the amount of energy emitted.
The types of UV light include the following:
- UVA light gives off the least amount of energy. This is the primary type of ultraviolet light you’re exposed to when in the sunlight. It can cause skin damage.
- UVB light describes the middle portion of the UV spectrum. Only a small amount of sunlight contains UVB, which causes skin cancer and sunburns.
- UVC is the most energetic ultraviolet light. Most UVC light that comes from the sun gets absorbed by the ozone layer. There are also man-made sources of UVC light used to disinfect air, surfaces, and liquids.
How UVC Kills Viruses
UVC light kills viruses and bacteria by damaging proteins and nucleic acids, making it impossible for germs to survive. It has proven effective in killing SARS-CoV-2, which causes COVID-19.
The American Journal of Infection Control (AJIC) published a study indicating that UVC light kills more than 99% of germs, including coronavirus, in 30 seconds. The study indicates that far-UVC light between 207 and 222 nanometers is highly effective in eradicating the coronavirus. Additionally, far-UVC doesn’t damage your eyes and skin as much as other types of UVC light.
UVC Light and Air Disinfection
Far-UVC light might kill up to 99.9% of airborne viruses such as coronaviruses. More studies are needed to prove this includes the SARS-CoV-2. UVC light kills viruses and germs on surfaces, in air, and in liquids. Since it’s also safer for your health, far-UVC might make the best option for disinfection.
