UV-C is the germicidal wavelength released by the sun, with wavelengths between 200-280 nanometres. Light within the UV-C wavelength can be used for disinfecting water, surfaces, and purifying air. When the UVC light is shined on bacteria, viruses, and other pathogens, it deactivates their DNA as well as destroying their ability to multiply and ultimately killing them.
The Effectiveness of UV sanitation can vary based on a few factors, including the length of exposure to bacteria, intensity of the radiation and a microorganism’s resistance to said radiation. The best method to face some of these variables is delivering multiple passes of exposure. Exposing the subject, you would like to sanitize multiple times will ensure that the bacteria with a bit more resistance will also have their DNA deactivated.
