Radiocarbon dating thermoluminescence archaeology

Based on a discipline of geology called stratigraphy, rock layers are used to decipher the sequence of historical geological events.

Relative techniques can determine the sequence of events but not the precise date of an event, making these methods unreliable.

Fieldwork (within Southern England) including in-situ radioactivity measurements, sample collection and travel to and from site can be undertaken at a daily rate of £300 VAT.

We are also able to conduct sample collection outside of the UK if the client is willing to cover additional transport, accommodation and subsistence costs.

The particular advantage of luminescence dating is that the method provides a date for the archaeological artefact or deposit itself, rather than for organic material in assumed association.

In the case of OSL sediment dating, suitable material (sand or silt-sized grains of quartz and feldspar) is usually available ubiquitously throughout the site.

The half-life of C is approximately 5730 years, which is too short for this method to be used to date material millions of years old.

However, it’s well known among radiation physicists that RDRs vary with location, season, solar activity, and even time of day.The error limits on the dates obtained are typically in the range of 5 to 10%.Our standard cost for OSL dating is £550 VAT per sample but prices can vary depending on the nature and number of samples (see our schedule of charges).Both assumptions become less realistic with the passage of time.Another problem with the TMRD is the calibration of the detector, since different crystals in an artifact can contain different amounts and/or types of luminescence material.

b) Absolute These methods are based on calculating the date of artefacts in a more precise way using different attributes of materials.
