The ozone layer
The ozone layer is an important filter of ultraviolet radiation. As the thickness of ozone layer decreases there is an increase in ultraviolet radiation reaching the ground. Many experts worry that this could lead to more skin cancer. Ultraviolet radiation in the UVA, UVB and UVC wavelength bands all penetrate our atmosphere in differing amounts, however our ozone layer blocks the UVC rays and most of the UVB rays. |
