In the age of COVID-19, more and more people are turning to UV-C light as a means to disinfect everything from surfaces to surgical instruments. As we've highlighted in other blogs, UV-C light provides a great method of disinfection against infectious diseases and viruses, without the drawbacks and after effects that accompany chemical disinfectants and fogs.
When using UV-C light for disinfection, it's important that the proper amount - or dose - of light is applied in order to effectively irradiate the target. Every microbe has a calculated dose for deactivation. This calculated dose is seen as a formula where dose is the product of irradiance and exposure time.
Verifying the actual amount of light reaching a surface is a critical step in the disinfection process, as many factors can impact this. In order to get an accurate measurement, a light meter that will integrate multiple measurements over the exposure time must be used.
