11.   Alpha radiation is the least pentrating of the three.

12.   Anxiety in the region runs so high that many researchers say they think it is causing more illness than the radiation is.

13.   As it was, the radiation was so intense that it overloaded gamma-ray sensors on at least seven scientific satellites, causing them to automatically shut down.

14.   Because the sensor is far more sensitive than regular film, less radiation is required.

15.   Also, try to schedule outdoor activities in the early morning or late afternoon, when UV radiation is much less intense.

16.   But radiation is indiscriminate.

17.   Could it be that it came from somewhere in space where radiation is much higher?

18.   For these men, he said, a combination of anti-hormone therapy and radiation is the standard approach.

19.   Haavisto said that even though the radiation was low-level, the debris should be removed.

20.   He pointed out that RF radiation is non-ionizing, meaning that it generates heat but does not damage the genetic material DNA, as nuclear fallout would.
