Abstract
The impact on archaeology of radiocarbon dating by accelerator mass spectrometry
D R Harris
23 - 43
AMS techniques have brought significant advances in 14C dating, principally by reduction of sample size needed, but also (theoretically) by the extension of the period datable. The small sample size allows greater selectivity to both archaeologist and radiocarbon chemist, and multiple samples can be taken. The AMS laboratories at Oxford, Toronto, and Tucson have already made substantial contributions to archaeological chronologies (eg Neo-BA in Britain) and to verification/falsification dating, and the long-term effects will be profound.
Radiocarbon dating by accelerator mass spectrometry: some recent results and applications
Robert E M Hedges
57 - 73
The potential of AMS to double the timespan of the radiocarbon method of dating has not yet been realized because of sample contamination effects. However, the small sample size allows extra selectivity. The measurement of isotopic ratio to better than 1% is already being achieved. So many dates are now available that new dating runs need to be carefully selected. Technical aspects are discussed, and applications mentioned include Giants' Hills long barrows, the Sproughton points, the Hazleton chambered tomb, and a lake sediment. E T Hall sums up the discussion meeting, pp 171-2, and calls for extreme care to ensure reliable dating.
