1.   But because ultraviolet radiation is a constant feature of solar radiation, the ozone layer is maintained.

2.   If ozone deterioration persisted, they warned, solar ultraviolet radiation would flood Earth.

3.   Indeed, infra-red light is chiefly responsible for the general warming effect of solar radiation.

4.   It is thought that a black hole absorbs any solar radiation that reaches it.

5.   Read in studio Scientists monitoring the level of solar radiation have warned people not to sunbathe without protection for more than forty minutes.

6.   They grow long tails as material streams away from their rocky cores driven by solar radiation.

7.   How can solar radiation be directly trapped and used?

8.   The use of solar collectors which can concentrate solar radiation sufficiently to generate the high temperatures needed for the thermochemical conversion of water is also a long-term possibility.
