Ultraviolet radiation, popularly called UV has been used for a long time as disinfectants for bio-contaminated air, and surfaces. With sanitization, and disinfection dominating every touchpoint of our lives given the current pandemic situation, there are instances of UV disinfection technology and a central vacuum system that disinfects everything from doorknobs and lift buttons to the air around us. But does UV technology really work as promised? The answers are muddy, especially because on one hand the WHO says we should not use a UV lamp to sanitize our hands, on the other hand, we have UV sterilization kits and boxes that promise to disinfect surfaces from bacteria and viruses. Let us dig a little deeper. How Does UV Light Actually Work? UV light is a low wavelength light, emitted by the sun. It comes in three forms UVA, UVB, and UVC.
