ultraviolet radiation
[ul-tra-VYE-o-let ray-dee-AY-shun]
UV radiation. Invisible rays that are part of the energy that comes from the sun. UV radiation also comes from sun lamps and tanning beds. UV radiation can damage the skin and cause melanoma and other types of skin cancer. UV radiation that reaches the Earth's surface is made up of two types of rays, called UVA and UVB rays. UVB rays are more likely than UVA rays to cause sunburn, but UVA rays pass deeper into the skin. Scientists have long thought that UVB radiation can cause melanoma and other types of skin cancer. They now think that UVA radiation also may add to skin damage that can lead to skin cancer and cause premature aging. For this reason, skin specialists recommend that people use sunscreens that reflect, absorb, or scatter both kinds of UV radiation.

Ultraviolet radiation
Invisible rays that are part of the energy that comes from the sun. Ultraviolet radiation can burn the skin and cause skin cancer. It is made up of two types of rays, UVA and UVB. UVB rays are more likely than UVA rays to cause sunburn, but UVA rays pass further into the skin. Scientists have long thought that UVB radiation can cause melamona and other types of skin cancer. They now think that UVA radiation also may add to skin damage that can lead to cancer. For this reason, skin specialists recommend that people use sunscreens that block both kinds of radiation.

Ultraviolet radiation (UV)
A portion of the electromagnetic spectrum with wavelengths shorted than visible light. The sun produces UV, which is commonly split into three bands of decreasing wavelength. Shorter wavelength radiation has a greater potential to cause biological damage on living organisms. The longer wavelength ultraviolet band, UVA, is not absorbed by ozone in the atmosphere. UVB is mostly absorbed by ozone, although some reaches the Earth. The shortest wavelength band, UVC, is completely absorbed by ozone and normal oxygen in the atmosphere.

ULTRAVIOLET RADIATION (UV)
Light waves shorter than the visible blue-violet waves of the spectrum, i.e., below 3900 Angstroms (Å). UV can be used for the disinfection of water.

Ultraviolet radiation (UV)
is the energy range just beyond the violet end of the v:isible spectrum. Most UV :is blocked by earth's atmosphere (particularly the stratospheric ozone layer) but some solar UV penetrates and aids in plant photosynthes:is and the production of Vitamin D in humans. Too much UV can burn the skin, cause skin cancer and cataracts, and damage vegetation. Volatile Organic Compounds (VOCs) are precursors of tropospheric ozone and photochemical smog. They are produced by human activities including the use of dry cleaning solvents.

| Wikipedia English - The Free Encyclopedia |
Ultraviolet
Ultraviolet (UV) light is electromagnetic radiation with a wavelength shorter than that of visible light, but longer than soft X-rays. It is so named because the spectrum starts with wavelengths slightly shorter than the wavelengths humans identify as the color violet (purple).
