THE EFFICACY OF ULTRAVIOLET RADIATION FOR GERMICIDAL PURPOSES

The COVID-19 pandemic has brought attention to the importance of keeping our surroundings clean and disinfected to mitigate the risk of contracting and spreading the virus. The use of ultraviolet (UV-C) radiation has been proven effective in disinfecting air, water, and surfaces, including reducing SARS-CoV-2 virus infectivity on surfaces to below detectable levels. However, limitations exist in the effectiveness of UVC radiation in inactivating viruses, particularly if the virus is not directly exposed to the radiation. This paper proposes a smart electronics system powered by an Arduino to design a 360-degree disinfection device using ultraviolet sterilization to solve the issue. The system aims to sterilize various items and surfaces to prevent the spread of COVID-19 and other germs.
