Sunlight Exposure - UVB Light

Sunlight Exposure - UVB Light: The sun emits three different types of UV radiation: UVA, UVB, and UVC.

All types of UV radiation have the potential to damage your skin, but each type affects your skin differently. UVA rays, which account for 95 percent of radiation that reaches the earth’s surface, cause wrinkles, “sun spots,” and other types of premature aging. They are also strongly linked to skin cancer. UVB rays, which affect skin’s top layer, cause skin cancer and most sunburns.

Although UVA and UVB rays pose the greatest risk for sun damage, people who work with welding torches or mercury lamps may be exposed to UVC rays, the most dangerous type of UV radiation.
