In recent weeks, UV-C lamps have come to the forefront because of the current pandemic we are living through.
Scientists and health experts from all around the world are racing against time to try to prevent the spread of the virus.One of the measures they suggest is to use germicidal or UV-C lamps.
First of all, we must point out that not all UV-C rays are effective for disinfection and sterilization of spaces although they are ultraviolet rays.
According to the WHO, ultraviolet light is classified as follows:
- UV-A (400-315 nm): It is typically lower in energy and it represents 95% of the sun’s energy that reaches Earth’s surface, and penetrates deepest into the skin. It is the one from which we get suntanned.
- UV-B (315-280 nm): It presents a higher energy level and penetrates the outermost layers of the skin. It causes sunburn, skin cancer and eye damage even if it carries just 5% of the sun’s energy, since most of it is absorbed by ozone layer.
- UV-C (280-200 nm) or germicidal UV: It is the most energetic of all ultraviolet light. The ozone layer and the atmosphere can completely absorb it. This is the perfect light for disinfection.
Why would UVC light slow the spread of coronavirus?
UVC radiation can rapidly inactivate microorganisms. The latest research shows that when bacteria and viruses are exposed to UV-C wavelengths, they absorb this radiation and a photolytic reaction takes place, in which pyrimidine dimers are formed to mess up the structure of nucleic acids (DNA and RNA). In this way, it helps to prevent viral replication and to achieve sterilization.

They are user-friendly. In order to ensure the disinfection’s efficacy, you just need to meet certain safety requirements.
