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.When a small sample of ancient pottery is heated it glows with a faint blue light, known as thermoluminescence or TL.
Although it is mainly used to supply photomultipliers, Hi Vo can be employed with any device needing high voltage and low current supply.
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 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).
