Louvain Natural Radiocarbon Measurements VII

Abstract

The following list comprises selected measurements made during 1967–68. The method is essentially the same as previously described. A 0.6 L proportional gas-counter at 3 atm CH 4 pressure is used. Ages are given relative to A.D. 1950 and half-life of 5570 yr has been assumed. The quoted error is the experimental standard deviation and includes the uncertainty on the unknown sample, the modern standard and the background.
