Invisible exposure : the science of ultraviolet rays

Darlene R. Stille, Farhana Hossain (Illustrator)
Soaking up the sun at the beach can be a fun, relaxing way to spend a summer day. But if you're not careful, ultraviolet rays from the sun can damage your skin. Government agencies have developed tools, such as the UV index and a UV ray warning system, to help people protect against the sun's rays. But UV Rays can be useful. They are used to study space, create fluorescent bulbs, and even treat certain skin diseases. Headline Science uses news stories and everyday applications to explain the science behind UV Rays
