Advanced Physics I am an engineering student and am designing something to kill bacteria on a strawberry patch but need help guring out a few things dont know if im asking right question just need any kind of help I can get thanks If you have a 253.7 nm UVC light bulb how much UV dose would it take to kill bacteria on a strawberry. How much is absorbed by the strawberry? I need any kind of calculations and equations or ideas. Thanks UV dose is the measurement of the amount of germicidal light that is absorbed by a particle as it passes through a UV system
