Abstract:
Underground physics laboratories offer an option for the investigations of rare processes as proton decays, neutrinoless double-beta decay, direct measurements of the mass of neutrino, or processes initiated by neutrinos or dark matter components. A good understanding of the natural radioactivity background is essential for the success of all types of experiments.Two classes of sources for radioactive background in underground are investigated in this contribution: a) self-radioactivity and radioactivity induced by reactions of cosmic rays (neutrinos/antineutrinos, muons) in the sodium and chlorine isotopes in the rocks of the cavern; b) unwanted reactions produced directly in the detector material, considering the liquid argon option.All estimations were carried out for the case of depths bellow 1000 m.w.e, but a discussion of the differences in the case of deeper underground laboratory is done.
