1.   Because natural radiation nowhere reaches the barest fraction of this level, Battista believes that Deinococcus evolved to withstand conditions of extreme dryness.

2.   Neither the British nor the Irish government denies that radiation is reaching these shores from the complex.

3.   Scientists elsewhere are not so sure, concerned that radiation could reach the ocean through a porous layer of limestone.

4.   Their radiation therefore reaches us as visible blue light rather than invisible ultraviolet rays.

5.   Uranium is far more mobile than cesium, and Brodeur said the newfound radiation might have reached the groundwater.

6.   Organizers say that ozone depletion has reached unprecedented levels, allowing more harmful UV-B radiation to reach the earth.

7.   Since radiation can reach complex geometrical shapes compared to the ability of gas fumigation to do so, it gives more uniform results throughout the product being irradiated.
