Cosmic Radiation

Cosmic radiationradiationcosmic (high-altitude radiation) consists mainly of fully ionized atomic nuclei (approx. 98%). In addition, significant components are electrons (approx. 2%). The origin of cosmic radiation is not precisely known. It is assumed that a very large proportion comes from the Milky Way. Active galactic nuclei, radio galaxies, and gamma-ray bursts are considered as extragalactic sources. The detection is predominantly indirect. The formation and acceleration of cosmic primary particles is a very active field of research.radiationcosmiccomposition  radiationcosmicorigin
