The Rb-Sr method is based on theβ-decay of8 7Rb which decays to8 7Sr with a half life of 48.8 × 109years. This half-life corresponds to the recommended decay constant (Steiger and Jäger, 1977) of 1.42 × 10−11/y. In the last years two different decay constants have been used.:λ(8 7Rb) = 1.39 × 10−11/y andλ(8 7Rb) = 1.47 × 10−11/y.
