Laser work and similar operations create intense concentrations of heat, ultraviolet, infrared, and reflected light radiation. A laser beam, of sufficient power, can produce intensities greater than ...

Radiation is energy that moves from one place to another in a form that can be described as waves or particles. We are exposed to radiation in our everyday life. Some of the most familiar sources of ...

Space is tough on materials. Radiation, UV light, atomic oxygen and sharp temperature swings can degrade metals, polymers and coatings over time. This article looks at the current ways researchers are ...
