Neutrino oscillation experiments have proved that neutrinos are massive particles but the assessment of their absolute mass scale is still an outstanding challenge in today particle physics and cosmology.The laboratory dedicated to effective electron-neutrino determination ones based on study single beta decay or electron capture (EC) decay.Exploiting only energy-momentum conservation, this kinematic measurement one which permits estimate neutrino masses without theoretical assumptions nature it truly modelindependent.To date most competitive isotopes for a calorimetric 187 Re 163 Ho.While first decays beta, latter via capture, both Q-value around 2.5 keV.The Ho EC appealing alternative because few nuclei needed self-calibrating measurement.In context MARE project, rhenium thermal detectors has been born.We report here status Milan with Rhenium activity concerning production radioactive isotope framework MARE.
