Radiocarbon dating and thermoluminescence use
Radiocarbon Dating of Single Compounds Isolated from Pottery Cooking Vessel Residues. Stott, A W Berstan, R Evershed, P Hedges, R E M Bronk Ramsey, C and Humm, M J 2001. Age analyses of materials and sherds from several sites are shown in this work. C beta counting on associated material, accelerator mass spectrometry on carbon traces on and within the sherd, thermoluminescence studies on minerals within the sherd, and stylistic form. Should I be concerned about artificial irradiation? If the radioactivity of the pottery itself, and its surroundings, is measured, the dose rate, or annual increment of dose, may be computed. Warning about fakes using ancient materials What about airport x-rays and radiography? Thus, when one measures dose in pottery, it is the dose accumulated since it was fired, unless there was a subsequent reheating.
The age of the pottery, in principle, may then be determined by the relation Age = Accumulated dose / Dose per year Although conceptually straightforward, TL has proven to to be far from simple in practice.
From the inside out: Upscaling organic residue analyses of archaeological ceramics. A combination of at least two independent techniques is indispensable for the highest level of confidence.
Each technique has its own frequently encountered non-laboratory sources of error.
Radiocarbon dating: radioactive carbon decays to nitrogen with a half-life of 5730 years.
In dead material, the decayed 14C is not replaced and its concentration in the object decreases slowly.
