How can i calculate UV irradiance value ? I am currently working on UV sanitation system. My aim is to kill 90-99 % microbes on the surface in around 30-40 sec. time. When i check for Uv-C lamp providers their data is given in UV output ( in Watts ) but for selection of suitable lamp, i will need data of UV Irradiance ( watts sec / cm2) .
