What is irradiance?
If you are looking for a non-chemical UVC disinfection device and want to be sure that there is enough irradiance to do the job, you need to check how much UV radiation falls on the contaminated surface. The critical factor in ensuring this are the power and time to ensure appropriate dose is received on these surfaces.
Only if irradiance is known time required to achieve the required dosage can be calculated, however if irradiance is not known then you will be in the dark and creating possibly a new pandemic of super bugs. The table below gives some information about the critical levels and serves as a particularly good reference point.
All AUM Medtech UVC Devices come with measured UVC irradiance at 3,6,9,12,15,20 & 25 feet.
