Sun is the primary source of energy that emits electromagnetic radiation of different wavelengths. The part of radiation beyond visible light is called ultraviolent (UV) radiation, which is not seen by human eye. UV radiations are classified according to different energy and wavelengths. UV radiation in earth's atmosphere absorbs mostly UVA and UVB.

UV intensity is highly dependent upon the position of sun (Duchêne, Lakey & Repacholi, 2001).

Health Risk Associated with Ultraviolent Radiation

There are numerous health hazards associated by UV exposure. However, degree of effect varies specie to specie. In humans, prolong exposure to such ...
