How much uv does the ozone layer absorb

NettetThe ozone layer (which absorbs from about 200 nm to 310 nm with a maximal absorption at about 250 nm)[7]is very effective at screening out UV-B; for radiation with a wavelength of 290 nm, the intensity at the top … NettetHow much UV light does ozone absorb? Ozone absorbs the most energetic wavelengths of ultraviolet light, known as UV-C and UV-B, wavelengths that harm living things. Oxygen molecules absorb other forms of ultraviolet light, too. Together, ozone and oxygen molecules are able to absorb 95 to 99.9% of the ultraviolet radiation that gets to our …
