The half-life of the nucleus C-10 has been determined by detecting its decay positrons in an E-Delta E fast scintillator telescope and recording the data in event mode. Care was taken to exclude the effects of possible contaminant activities and of pileup in the linear electronic systems. A value of 19.282(11) s has been obtained, which is in good agreement with two of the three previous measurements, but not with the most recent.
