Radiocarbon dating thermoluminescence archaeology

For example, the processes by which the technique is performed and the associated skills and knowledge required to produce accurate determinations will necessarily impact the availability of the technique, but availability (and the associated monetary cost) is not an intrinsic property of the technique itself.

In order to evaluate the technique itself, an idealised situation will be considered, whereby it is assumed that an archaeologist would have equal and otherwise unbiased access to a range of dating techniques, and it remains only to choose the one most appropriate to the situation at hand.

Inaccuracies derived from these two sources cannot be effectively dealt with by multiple readings, as in the case of inaccuracies introduced by incorrect measurement, and so must be estimated and compensated for (Ramsey 2009).

This unstable isotope of Carbon then enters the food chain, and in doing so, forms part of all organic matter (Bayliss et al. Broadly speaking, anything that was once alive can therefore theoretically have measured the levels of radiocarbon it now contains.This is especially a problem with material that has been stored sub-optimally, handled with unclean hands, or treated with organic chemicals for conservation purposes (Pohl et al. Unlike dendrochronology, which relies on multiple correspondences to provide a solid chronology (as discussed later), radiocarbon dating has no inbuilt self-test mechanism, so errors of this sort are hard to detect and hard to quantify.Radiocarbon dating is predicated on the assumption that the level of C in the atmosphere at the time and that these levels of both biosphere and atmosphere are consistent over the entire globe.For example, bone samples without enough remaining collagen had to be disregarded in a radiocarbon dating exercise targeting the Cotswold-Severn Long Barrows (Smith & Brickley 2006).Owing to the plateaux in the calibration curve (see Figure 1 below), samples with true dates on these plateaux cannot produce dates with any precision, and may return such wide ranges that the technique may not be the best approach to dating material from that time period.
