All existing "positive" results on two-neutrino double-beta decay in different nuclei were analyzed. Using procedure recommended by Particle Data Group weighted average values for half-lives of 48Ca, 76Ge, 82Se, 96Zr, 100Mo, 100Mo-100Ru (0+ 1), 116Cd, 150Nd and 238U were obtained. Existing geochemical data were analyzed and recommended values for half-lives of 128Te and 130Te are proposed. We recommend to use these results as the most precise and reliable values for half-lives at this moment.
