| The decaying atoms emit positrons, which encounter electrons and are annihilated, releasing pairs of gamma rays. |
| High-frequency energy, such as X rays, gamma rays, and cosmic rays, occupies the other end of the spectrum. |
| This energy is often in the form of ionizing radiation like x-rays or gamma rays. |
| But the very same atmosphere is opaque in most frequencies of far infrared, ultraviolet, x-rays and gamma rays. |
| The burst of gamma rays and X-rays even disturbed the Earth's ionosphere, causing a sudden disruption in some radio communications. |
| The frequency of gamma rays is far too high and that of radio waves is far too low to interact with these kinds of vibrations. |
