Web30 de mar. de 2012 · Abstract: Pulsed UV lasers can provide useful "testbeams" for observatories that useoptical detectors, especially fluorescence detectors, to measure high energycosmic-rays. The light observed by the detector is proportional to the energyof the laser pulse. Since the absolute laser energy can be measured locally, awell-calibrated … WebAltitude - UV radiation increases with altitude (height above sea level) because there is less atmosphere to absorb the damaging rays. The UV index measured in Edmonton will be less than that measured at the top of a mountain in Jasper. At an altitude of around 2,000 metres, the amount of UV radiation can be up to 30% higher than at sea level.
WebIonizing radiation can damage the DNA (genes) in cells, which in turn may lead to cancer. But even the highest-energy UV rays don’t have enough energy to penetrate deeply into the body, so their main effect is on the skin. UV radiation is divided into 3 main groups: UVA rays have the least energy among UV rays. WebUltraviolet (UV) light has shorter wavelengths than visible light. Although UV waves are invisible to the human eye, some insects, such as bumblebees, can see them. This is similar to how a dog can hear the sound of a …
