Ultraviolet A radiation Definition

Ultraviolet A Radiation is the 320 to 400 nanometers portion of the sun's radiant electromagnetic energy spectrum, partially absorbed by the Earth's protective stratospheric ozone layer. It is may be up to 1,000 times more intense than UVB. UVA radiation can penetrate to underlying tissues of the skin and cause photo-aging or long-term skin damage. Recent ozone depletion has permitted more UV radiation to reach the Earth's surface with a wide range of potentially damaging health effects related to skin, eyes, and immune system. (NCI04)
