Answer Details

The gas that is most useful in protecting humans against solar radiation is ozone. Ozone is a molecule made up of three oxygen atoms and is present in the earth's atmosphere, where it forms a protective layer known as the ozone layer. This layer helps to block harmful ultraviolet (UV) radiation from the sun, which can cause skin cancer, cataracts, and other health problems in humans. Chlorine, carbon (IV) oxide, and hydrogen sulphide are not known to be useful in protecting humans against solar radiation.
