Two aspects of cosmic rays and cosmology are considered here. Firstly, the relevance of extragalactic cosmic rays to the radiation – and magnetic – fields in the Universe and secondly the contribution of Galactic cosmic rays (or other entities allied to them) to the 'foreground' in analysis of the cosmic microwave background (CMB).

Gas-phase chemistry in the interstellar medium is driven by fast ion-molecule reactions. This, of course, demands a mechanism for ionization, and cosmic rays are the ideal candidate as they can operate throughout the majority of both diffuse and dense interstellar clouds.

This book is not a book on high energy physics and particle interactions. We have, however, to give the reader some information on the structure of matter and the interactions between its building blocks, because these are necessary for the understanding of the phenomena of cosmic ray acceleration, propagation in the Universe, and detection.

As we discussed in the previous chapter, primary cosmic rays interact with the atmosphere and produce fluxes of secondary, tertiary, etc. particles. All these particles together create a cascade, called an air shower. In principle, measurements of air shower particles can be interpreted in terms of the energy spectrum and the composition of the primary

Primary cosmic rays almost never reach sea level. Secondary particles do. Hadrons, electrons and γ-rays interact immediately with the rock and are quickly absorbed. 10 meters of rock provide two to three times more column depth than the whole atmosphere. Only very high energy muons (E > 500 GeV) can penetrate deep underground where they can be detected
