T his page is dedicated to a much deeper look into Electromagnetic Radiation (EMR) spectrum and the Ultraviolet (UV) Index as in relation to lighting sources. The UV Index is an international standard measurement of the strength of sunburn-producing UV radiation at a particular place and time. The scale was developed by Canadian scientists in 1992, then adopted and standardized by the UN's World Health Organization and World Meteorological Organization in 1994. The UV Index is designed as an open-ended linear scale, directly proportional to the intensity of UV radiation that causes sunburn on human skin. The purpose of the UV Index is to help people effectively protect themselves from UV radiation, which in excess, causes sunburn, skin aging, DNA damage, skin cancer, immunosuppression, and eye damage.http://www.who.int/uv/intersunprogramme/activities/uv_index/en/index2.html
