Tata Institute Radiocarbon Date List V

The C 14 dates presented here were obtained by counting methane, using the technique described earlier (Agrawal et al. , 1965a). In accordance with the decision of the Sixth Pullman Conference (Internat. Gonf., Pullman, 1965) and the editors’ advice we continue to give dates based on τ 1/2 = 5568 years. For converting dates to A.D./B.C. scale, 1950 has been used as reference year. Ninety-five per cent activity of N.B.S. oxalic acid has been used as modern standard.
