Tritium was extracted from the meteorites by melting samples with high- frequency heating in chambers with tritium-free hydrogen as carrier. The hydrogen obtained was oxidized to H/sub 2/O and separated from CO/sub 2/. This oxidation and separation was repeated three or four times. The tritium was then measured in a proportional anticoincidence counter. An isotopes analysis of helium was made with a 30-cm 60 deg mass spectrometer without source magnet. The results of the measurement are tabulated. Radiation ages of three chondrites were of the order of magnitude of 10/sup 7/ years, in agreement with previous measurements. (J.S.R.)
