Cosmic Rays: The Most Energetic Particles in the Universe

  • James W. Cronin

Abstract

Cosmic rays are a source of ionizing radiation incident on the whole earth. The intensity of this ionizing radiation varies with magnetic latitude, with altitude, and with solar activity. The attribution “cosmic rays” is misleading in that the radiation consists principally of fully ionized atomic nuclei incident on the earth from outer space.
