What is Ultraviolet Radiation?
Ultraviolet (UV) radiation is electromagnetic radiation of a wavelength between 100nm (nanometers) and 400nm. Since this is less than the wavelength of visible light, UV radiation cannot be seen. There are 3 types, each of different wavebands:
UV Type |
Wavelength |
Hazard Rating |
UV-A |
400-315nm |
Low |
UV-B |
280-315nm |
Medium / High |
UV-C |
100-280nm |
High / Very High |
UV radiation is associated with a range of applications in the University, such as
