Yes, the UVC systems can be used to disinfect both the air and surfaces. The UVC disinfects the surface wherever its light shines, and the same UVC system can disinfect the air when it forces the air through the lamp’s surface. The UVC can disrupt the DNA/RNA of the pathogens in the air as the …
The National Institute for Occupational Safety and Health (NIOSH) USA recommends that the time of exposure to intensity of 100uW/cm2 at 253.7nm UV-C should not exceed 1 minute. When averages over 10 sec, this value is 600uW/cm2; and over 1 sec, it is 6000uW/cm2. These values are significantly lower than any UV light currently available …
UVC is widely used to disinfect the air and surfaces. Each microbe requires a specific UV dosage for its DNA and RNA to be completely damaged. In other words, the UV dosage for bacteria and virus are different from each other. Each UV lamp manufacturer specifies UV intensity in µW/cm2 (reads microwatt per square centimeter), …
