1.   Large areas, including the United States, continue to get increasingly harmful ultraviolet radiation.

2.   Substantially smaller amounts of shielding will undoubtedly admit much larger fluxes of harmful radiation.

3.   VDUs are suspected by some of causing eye strain, postural problems and even of spreading harmful radiation across the room.

4.   Sun creams work by blocking harmful ultraviolet radiation.

5.   And the magnetic type would not use chlorofluorocarbons, which eat away ozone in the upper atmosphere that protects Earth from harmful ultraviolet radiation.

6.   In the process many expose their skin and eyes to a heavy dose of harmful ultraviolet radiation.

7.   It is designed to measure potentially harmful radiation near Mars as a critical factor in planning any future exploration by humans.

8.   Scientists hope to learn whether meteor storms degrade the ozone shield protecting life on earth from harmful ultraviolet radiation.

9.   Separately, ozone is formed high in the stratosphere, where it shields the planet from harmful radiation.

10.   That atmospheric layer protects the earth from harmful ultra violet radiation that can cause skin cancer.
