Can UV Light Be Used to Kill Airborne Flu Virus?
As the researchers explained, broad-spectrum UVC light kills viruses and bacteria, and it is currently used to decontaminate surgical equipment.
But this type of light can cause skin cancer and cataracts, so it’s not used in public spaces.
How does UV light kill viruses?
At certain wavelengths, UV is mutagenic to bacteria, viruses and other microorganisms. Particularly at wavelengths around 260–270 nm, UV breaks molecular bonds within microorganismal DNA, producing thymine dimers that can kill or disable the organisms. Mercury-based lamps emit UV light at the 253.7 nm line.
How long does it take for UV light to kill bacteria?
The average bacterium will be killed in ten seconds at a distance of six inches from the lamp in an American Ultraviolet Germicidal Fixture.
Does ultraviolet light kill bacteria?
Q. – How Does UV Light Kill Bacteria? A. – UV or ultraviolet light is a type of radiation. If a cell cannot reproduce, then the cell cannot cause infection, which is how UV light kills bacteria.
Does UV light kill norovirus?
Researchers Prove UV Light Can Kill Flu Viruses Without Harming Humans. Far-ultraviolet C (far-UVC) light can kill flu viruses and could reduce the incidence of flu infections. This light is also used to sterilize surgical equipment.
How effective is UV sterilization?
UV has been proven effective against a broad spectrum of microorganisms. Bacteria are generally easier to inactivate than viruses, with fungi and spores being even harder to inactivate with UV. Safety. As UV-C provides radiation, it is not safe to be in the room while UV-C disinfection is taking place.
