In the electromagnetic radiation spectrum, ultraviolet (UV) radiations cover the wavelength range of 100–400 nm, which is a higher frequency (υ) and lower wavelength (λ) than visible light. Disinfection by using UV light is nothing new as it’s been a useful technology for over 40 years, contributing to clean water and clean air and there are many consumer devices using UV light to disinfect things. In the recent times of COVID-19 pandemic, UV radiations/light has attracted great significance to kill coronavirus or disinfect medical & electronic equipment, buildings by using high UV doses and using low doses for humans. This article gives a brief summary on the utility, devices and safety with UV radiations to deal with coronavirus

Disinfection by using UV light is nothing new as it’s been a useful technology for over 40 years, contributing to clean water and clean air and there are many consumer devices using UV light to disinfect things. In the recent times of COVID-19 pandemic, UV radiations/light has attracted great significance to kill coronavirus or disinfect medical & electronic equipment, buildings by using high UV doses and using low doses for humans.
