Ultraviolet (uv) radiation is electromagnetic energy with a wavelength just shorter than that of visible light.
Uv radiation has a shorter wavelength and is more energetic than visible light. Depending on its wavelength, it can get through the ozone layer and affect our health in different ways. The shorter the wavelength, the more harmful the uv radiation. However, shorter wavelength uv radiation is less able to penetrate the skin.
Ultraviolet (uv) detectors work by detecting the uv radiation emitted at the instant of ignition. While capable of detecting fires and explosions within 3–4 milliseconds, a time delay of 2–3 seconds is often included to minimize false alarms which can be triggered by other uv sources such as lightning, arc welding, radiation, and sunlight.

Workshop, it is instructive to repeat a portion of the introduction to the report. As a result of stratospheric ozone reduction, there is a real potential for the flux of ultraviolet radiation (uv) to increase at the earth's surface. While there is little evidence that this has yet occurred to a measurable extent except in polar regions, this.
