UV Radiation Emanating From the Sun is a Big Risk Factor For Cancer

Radiation is a risk factor for cancer and we have to take steps against ultra violet (UV) radiation from sun. This is of serious concern because we are now exposed to more of this radiation due to the depletion of the ozone layer by the chlorofluorocarbons (CFCs)-substances. CFC substances are present in aerosol sprays, air conditioners, and most refrigerant systems.
