Uvc Light
Uv c light which has the most energy of all three types is the most harmful but it fortunately doesn t reach the earth s surface because our atmosphere absorbs it.
Uvc light. Nearly all the uv radiation that reaches earth is uva because most of uvb and all of uvc light is absorbed by the ozone layer according to the centers for disease control and prevention. Uvgi is used in a variety of applications such as food air and water purification. Uv germicidal lamp uv c bulb light with 5ft cord and plug cover up to 100 sq. Ultraviolet light is a type of electromagnetic radiation that makes black light posters glow and is responsible for summer tans and sunburns.
Uvc refers to ultraviolet light with wavelengths between 200 280 nanometers nm. Room 110v 6w uvc ozone free 3 9 out of 5 stars 177 18 90 18. However too much exposure to uv radiation is. It is particularly good at destroying genetic material.
There is also a third type. Ultraviolet germicidal irradiation uvgi is a disinfection method that uses short wavelength ultraviolet ultraviolet c or uv c light to kill or inactivate microorganisms by destroying nucleic acids and disrupting their dna leaving them unable to perform vital cellular functions. Light in the uvc wavelength can be used for disinfecting water sterilizing surfaces and destroying harmful micro organisms in food products and in air. In the graph can be seen that germicidal action is maximized at 265 nm with reductions on either side.
Uvc light has a long history as a proven disinfectant at places like hospitals and laboratories and businesses including airlines hotels and retail spaces have been relying on the invisible. This relatively obscure part of the spectrum consists of a shorter more energetic wavelength of light.
