Abstract
The measurements reported in this list were made in the Louvain C14 Dating Laboratory in 1968 with the 0.6L CH4 proportional counter. The counter generally operates at 3 atm pressure. Samples too poor to provide 2 L methane are measured at 1000 mm Hg pressure. Ages are calculated on the basis of a C14 half life of 5570 yr and are quoted with 1σ counting error. The description of each sample is based on information provided by the submitters.
