The UV index is a linear scale; each increase in value corresponds to a constant decrease in time to sunburn. Higher values represent a greater risk of sunburn (which is correlated with other health risks) due to UV exposure. An index of 0 corresponds to zero UV radiation, as is essentially the case at night. An index of 10 corresponds roughly to midday summer sunlight with a clear sky when the … NettetUV-C light disinfection.
