| cosmic radiation |
Cosmic rays can loosely be defined as energetic particles originating outside of the Earth. The composition includes electrons, protons, gamma rays, and atomic nuclei from a large region of the periodic table. The kinetic energies of these particles span over fourteen orders of magnitude, with the flux of cosmic rays on the Earth's surface falling approximately as the inverse cube of the energy. The wide variety of particle energies is reflected in the wide variety of sources. ...
