In the work arguments are provided in favor of using tritium as an (anti)neutrino source in experiments on research of neutrino electromagnetic properties. It is described the evolution of the tritium (anti)neutrino source design with the intensity of 40B MCi with respect to experiments on defining the neutrino magnetic moment. The physical experiment particulars are discussed with account for physical, chemical and radiational properties of tritium. In continuation of work [1] on the research of neutrino coherent scattering at atoms and nuclei of liquid helium present in the superfluid state, as well as and on the research of neutrino electromagnetic properties, it is proposed using a tritium source with the intensity of 10B MCi. Specifics of such experiments are discussed.
Keywords: neutrino, (anti)neutrino tritium source, magnetic moment, electromagnetic properties.

The cosmic silence of the underground Gran Sasso laboratory together with the exceptional radio purity of the liquid scintillator, has allowed Borexino to investigate the radiogenic heating of the Earth's interior and to contribute to various fields of experimental neutrino astronomy. This contribution is aimed to summarize the results obtained by Borexino on geo-neutrinos and on possible extra-terrestrial sources of antineutrinos such as supernovae explosions and solar flares.
Keywords: geoneutrino, Borexino, neutrino physics.
