Ultraviolet (UV) radiation. Appears in: Environment and health. One in every three cancers diagnosed is a skin cancer. The main factor that predisposes to the development of skin cancer is exposure to ultraviolet (UV) radiation, traditionally from the sun and more recently from artificial tanning sunbeds. Both solar radiation and sunbeds are
For most individuals, the main source of exposure to ultraviolet (UV) radiation is the sun. Nevertheless, some individuals are exposed to high doses of UV through artificial sources. Sunbeds and sunlamps used for tanning purposes are the main source of deliberate exposure to artificial UV radiation. Physical characteristics of UV radiation Ultra-violet Radiation. Ultraviolet (UV) is the electromagnetic radiation covering the range 100 to 400 nm. It is commonly divided into 3 ranges of varying wavelength: The direct potential radiation hazard to health arises from UV with wavelengths greater than 180 nm. UV at lower wavelength is readily absorbed in air and only exists in a vacuum.

Apr 13, 2018 · Lights That Give Off UV Rays. Ultraviolet light has a shorter wavelength than visible light. It is not visible to human eyes, but can affect human health, most notably by causing skin cancer. UV light can be useful to humans, as well. Reptile owners, for example, may use artificial UV bulbs to provide their reptiles with Vitamin D, and small
Indoor tanning lamps emit UVA and UVB radiation at levels that can be as much as 15 times stronger than the sun. 2 UV radiation, both from natural and artificial sources, such as tanning beds and sun lamps, has been classified by the US Department of Health and Human Services as a known carcinogen (cancer causing agent). 3 May 27, 2004 · It is well known that exposure to ultraviolet radiation damages hair fiber. Dryness, reduced strength, rough surface texture, loss of color, decreased luster, stiffness and brittleness of hair are caused by sun exposure. Photochemical degradation of hair results in attack on both hair proteins and melanins. Hair protein degradation is induced rZf0Co. 95 246 187 13 254 105 226 72 478
