ozon tabakası, stratosferde, deniz yüzeyinden yaklaşık 20 mil kadar üstünde yer alan ve güneşten gelen zararı ultraviyole radyasyonu bloke etmeye yetecek ozon içeren bir tabaka
From a scientific perspective there is some indication that a nuclear war could deplete the earth's ozone layer or, less likely, could bring on a new Ice Age - but there is no suggestion that either the created order or mankind would be destroyed in the process. Herman Kahn
The highest levels of ozone in the atmosphere are in the stratosphere, in a region also known as the ozone layer between about 10 km and 50 km above the surface (or between about 6 and 31 miles).
The ozone layer is a layer in Earth's atmosphere which contains relatively high concentrations of ozone (O3). This layer absorbs 93-99% of the sun's high frequency ultraviolet light, which is potentially damaging to life on earth.
