Archeology radiocarbon dating

Regardless of the particular 14C technique used, the value of this tool for archaeology has clearly been appreciated.

Desmond Clark (1979:7) observed that without radiocarbon dating "we would still be foundering in a sea of imprecisions sometime bred of inspired guesswork but more often of imaginative speculation." And as Colin Renfrew (1973) aptly noted over 30 years ago, the "Radiocarbon Revolution" transformed how archaeologists could interpret the past and track cultural changes through a period in human history where we see among other things the massive migration of peoples settling virtually every major region of the world, the transition from hunting and gathering to more intensive forms of food production, and the rise of city-states.

Probably the most important factor to consider when using radiocarbon dating is if external factors, whether through artificial contamination, animal disturbance, or human negligence, contributed to any errors in the determinations.

If your project requires access to radiocarbon dating facilities, you must apply for access to the NERC Radiocarbon Facility (NRCF), which is funded by the AHRC and NERC.

For further details on how to apply please see the NRCF website.

You may only request radiocarbon dating costs from AHRC through your grant application if confirms that they are not able to provide a suitable service.

Using conventional decay or beta counting, sample sizes ranging from about 0.5 to 10 g of carbon are typical.

Is radiocarbon dating accuracy indeed more reliable to determine Bible chronology than traditional dating methods that rely on archaeological evidence that looks at strata context? The material’s period of growth might be many decades from the era in which it was used or reused, say, in building construction.Radiocarbon dating was the first chronometric technique widely available to archaeologists and was especially useful because it allowed researchers to directly date the panoply of organic remains often found in archaeological sites including artifacts made from bone, shell, wood, and other carbon based materials.In contrast to relative dating techniques whereby artifacts were simply designated as "older" or "younger" than other cultural remains based on the presence of fossils or stratigraphic position, 14C dating provided an easy and increasingly accessible way for archaeologists to construct chronologies of human behavior and examine temporal changes through time at a finer scale than what had previously been possible.However, as with any dating technique there are limits to the kinds of things that can be satisfactorily dated, levels of precision and accuracy, age range constraints, and different levels of susceptibility to contamination.Radiocarbon dating is especially good for determining the age of sites occupied within the last 26,000 years or so (but has the potential for sites over 50,000), can be used on carbon-based materials (organic or inorganic), and can be accurate to within ±30-50 years.With isotopic enrichment and larger sample sizes, ages up to 75,000 years have been measured (Taylor ).
