What is Ultraviolet Light?
"Ultraviolet (UV) light is electromagnetic radiation with a wavelength shorter than that of visible light, but
longer than soft X-rays. It can be subdivided into near UV (380–200 nm wavelength), far or vacuum UV
(200–10 nm; abbrev. FUV or VUV), and extreme UV (1–31 nm; abbrev. EUV or XUV)." [more]
"Everyone is exposed to UV radiation from the sun and an increasing number of people are exposed to
artificial sources used in industry, commerce and recreation. Emissions from the sun include visible
light, heat and UV radiation." [more]
Health concerns and protection
"UVA rays penetrate more deeply into the skin and may also be responsible for causing cancer and
wrinkles. Some sunscreen lotion now includes compounds such as titanium dioxide which helps protect
against UVA rays. Other UVA blocking compounds found in sunscreen include zinc oxide and
avobenzone." [more]
