Laboratory of Archaeometry (Carbon-14)

Researcher in charge: Y. Maniatis

The Laboratory of Archaeometry uses the gas (CO2) counting technique for C-14 measurements of archaeological and environmental samples. Each sample is combusted and the CO2 produced is measured inside cylindrical gas proportional counters. The laboratory possesses 8 such counters, four with a capacity of 4 litres and four with 3 litres. These counters are identical to those used in the Radiocarbon Laboratory of the Institute of Environmental Physics, University of Heidelberg and were built and tested there. In 1998 an integrated counting system consisting of six counters inside a common guard counter was installed together with a data logger which monitors the meteorological parameters affecting the intensity of the cosmic radiation flux and consequently the counters background. This new counting system combined with the pre-existing counters has improved significantly the precision of the radiocarbon dates obtained as well as the speed with which results are produced and delivered.
