UV-C dose required to kill microorganisms
Below is a list of microorganisms and the UV-C dose at 254 nm (displayed in J/m2) required to achieve a 90% (1 log reduction). UV dose (J/m2) = UV irradiance (W/m2) x exposure time (seconds) If you know the UV irradiance value then you can use our online UV dose calculator to determine the UV dose applied, which varies with time. In order to calculate further log reductions, you could – as a guide – multiply …
