Abstract:
This contribution reviews the sources of primary and secondary particles as background, which is important in underground environments used as laboratory for rare processes predicted by the Unification Theories in high energy and astroparticle physics. The mechanisms of production of hadrons and other secondary particles, as well as long-lived isotopes generated by cosmic-ray interactions are discussed. Characteristics of these particles, compiled from experiments and calculations from literature are presented and could be used as a reference for further studies.
