| ultraviolet radiation |
electromagnetic radiation in the wavelength range from 100 to 400 nanometers. It is shorter and more energetic than visible light but has essentially the same composition. Depending on its wavelength, it penetrates skin to different levels (more deeply in the case of UVA than UVB) and triggers different biological effects.

| ultraviolet radiation |
The energy range just beyond the violet end of the visible spectrum. Although ultraviolet radiation constitutes only about 5 percent of the total energy emitted from the sun, it is the major energy source for the stratosphere and mesosphere, playing a dominant role in both energy balance and chemical composition.

| ultraviolet radiation |
UV radiation, which falls between x-rays and visible light on the electromagnetic spectrum, is divided into three types, according to wavelength. These are: UVA (320-400nm), UVB (290-320), and UVC (200-290nm) (Clark, 1985).
