Ultraviolet UVC radiation (200 to 280 nm) deactivates bacteria and viruses by attacking their DNA. Their genetic information is destroyed. Micro-organisms lose their ability to reproduce and are annihilated. These viruses and bacteria are unable to develop immunity to UV-C rays.
One component of the electromagnetic spectrum, ultraviolet light, has a shorter wavelength than visible light. Infrared and X-rays are examples of other wavelengths of the light spectrum that are also invisible.
There are three types of UV light: UVA, UVB and UVC. UVC light has a wavelength range from 100 to 300 nm, but micro-organisms are particularly sensitive to light in the 240-280 nm region.
The energy of UVC light damages DNA and prevents micro-organisms from proliferating. The disinfection bulbs in our solutions emit UVC light, which has the most powerful disinfectant effect, with a wavelength of 254 nm.
UV-C radiation has been used as an air, surface, object and water disinfectant since the early 20th century. To date, all viruses and bacteria tested in laboratories continue to be annihilated during disinfection by UV-C light.
1903 - Niels Ryberg Finsen was awarded the Nobel Prize in Medicine for being the first person to use UV light to treat disease. In the 1950s, the Finsen curative lamp he created was used successfully.
1908 - UV-C was used to disinfect Marseille's municipal water supply.
1930 - Westinghouse created the first UV-C germicidal lamps for commercial use. They were mainly used in hospitals.
1950 - UV-C was added to air treatment machines. They played an important role in the prevention and eradication of tuberculosis.
2020 - DT-Solution began its efforts to combat the sudden COVID-19 pandemic with up-to-date, under-utilized UVC technology. At a time when demand for disinfection has exploded, DT-Solution has made it more sustainable, less expensive and more effective.
