Abstract

Constraints on the Earth’s composition and on its radiogenic energy budget come from the de- tection of geoneutrinos, i.e. electron antineutrinos produced in beta decays along the the decay chains of 238U and 232Th existing in the interior of our planet. The KamLAND and Borexino experiments recently reported the geoneutrino flux and other experiments are starting or planning in different countries of the world. We report here the main available results and the future per- spectives about these special probes of the Earth’s interior. Since reactor antineutrinos represent the main source of background in geoneutrinos detection, we also report updated evaluation of reactor antineutrino signals for the different experimental sites in the world, taking into account the most recent reactors operational data.
