UVC Light Testing Solution

UV light is electromagnetic radiation with wavelengths shorter than visible light but longer than X-rays. There are three types of ultraviolet light – UVA, UVB and UVC. UVA and UVB are what causes sunburns. Short-wave ultraviolet light (UVC) has the highest energy amongst the types of UV light and it can damage DNA. This is how UVC can sterilize surfaces by damaging the DNA of germs which it comes into contact effectively killing them.

WHAT IS UVC? 

UVC with wavelengths in the range 200nm to 280nm is considered "germicidal UV". UVC light from special germicidal lamps with kills germs, such as bacteria and viruses, and has been used as a means of disinfecting hospital wards and operating theatres for decades. 

The effectiveness of germicidal UV depends on the organic matter it’s used on, wavelength of the light, type of suspension, temperature, type of microorganism and UV intensity. 

WHY IS UVC TESTING IMPORTANT?

As UV-C is a type of UV light, it has the potential to damage human tissues such as skin and eyes when exposed to UVC light. To ensure that UVC emitting devices are safe to use and meet the conditions required to kill germs, it’s important to have these devices tested to be safe and effective in killing germs. Hence, there are certain guidelines and precaution that needs to be taken care of before such products are introduced to the market.
