Does UV Light Kill Viruses and Germs? Can we use it to clean our books?
It goes without saying that the chemical or water disinfection methods are rejected and not acceptable to clean the books and manuscripts in our libraries. The best alternative should be none liquid disinfection method, like light and/or air. The power of disinfection Germicidal UltraViolet light “UV” (also known as UV-C) has been known for more than 100 years and is widely used to purify water, air and surfaces. A crisis such as the one gripping the globe can serve to push research and innovation that will ultimately lead to better technology.
UV light provides rapid, effective inactivation of microorganisms through a physical process. When bacteria, viruses and protozoa are exposed to the germicidal wavelengths of UV light, they are rendered incapable of reproducing and infecting. UV light has demonstrated efficacy against pathogenic organisms, including those responsible for cholera, polio, typhoid, hepatitis and other bacterial, viral and parasitic diseases.
For many years, UV-C helped stop the spread of numerous pathogens by disinfecting frequently used surfaces “like the books in our case here” and UV light is very effective at inactivating viruses and bacteria as reported by the Illuminating Engineering Society (IES), UV-C is the most effective at disinfection.
UltraViolet Sterilization Effect
UltraViolet ray is a type of light located outside the purple ray of visible rays and its wavelength is between 100-400nm. Ultra violet rays display strong sterilizing impact against microorganism. The sterilization method of UltraViolet rays is to penetrate through the external cell membrane of bacteria, virus, enzyme, etc. and then destroys DNA required by virus to survive and multiply. There are many different sterilization methods, but the ultraviolet ray sterilization method is enjoying great popularity as it displays great Impact, Is absolutely harmless to the human body, does not damage the product, and can be used easily.
How Can UV be Utilized?
UV can be used as a sterilization technique for other types of disinfection. UV can disinfect the air in isolated spaces, which is particularly beneficial in a hospital setting. Installing UV devices like lamps and lights at the top of rooms and other areas of circulation can disinfect the air as it moves, improving both the air quality and the effectiveness of the UV sterilization.
What Type of UV Light is Best?
Most UV sterilization devices use UV-C light as the source of their disinfecting power. UV-C light is an effective solution for sterilization, which is why it is the most widely used light type. UVC, with wavelengths between 100 and 280nm, is very energetic. It is very dangerous to all forms of life (even with short exposures).
Why Use UV Sterilization?
UV sterilization is not a new technology, having been discovered in 1879. Discovered to be a useful technology for cleaning infectious spaces, more studies were done to determine the exact beneficial nature of UV for sterilization purposes. Since the 20th century, UV sterilization has been used to disinfect things like water and work surfaces. UV light is a shorter wavelength than visible light, and is able to penetrate and destroy the bodies of viruses and bacteria.
In several countries, UV-C has been used to disinfect money, buses and elevators, in addition to widespread uses in hospitals, so why not on borrowed books and magazines from your library.
