Ultraviolet (UV) radiation is a form of non-ionizing radiation that is emitted by the sun and artificial sources, such as tanning beds While it has some benefits for people, including the creation of Vitamin D, it also can cause health risks
- Radiation: Ultraviolet (UV) radiation - World Health Organization (WHO)
Solar emissions include visible light, heat and ultraviolet (UV) radiation Just as visible light consists of different colours that become apparent in a rainbow, the UV radiation spectrum is divided into three regions called UVA, UVB and UVC

- UV Index
The UV Index at any given time is presented as a number ranging from 0 to 14, representing values on a linear scale A UV Index value of 0 means that there is no UV radiation, and a UV Index of 10 is intended to represent the UV radiation of a clear summer day at around noon
- ultraviolet radiation - Encyclopedia Britannica
Ultraviolet radiation is produced by high-temperature surfaces, such as the Sun’s, in a continuous spectrum and by atomic excitation in a gaseous discharge tube as a discrete spectrum of wavelengths Can humans see ultraviolet radiation? No, ultraviolet radiation is undetectable by the human eye
