Cost of thermoluminescence dating
The typical turn-round time for providing a date is circa 3-4 months, although, rapid dating (circa 4-6 weeks or sometimes less, depending on machine time and sample type) using our fast track service can be undertaken.
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.Any remaining powder is dried and used for radioactivity measurements to complete the dating calculation. When the glue is dry, they are cut into slices 1/4mm thick with a fine diamond blade. Each slice is soaked in acetone after cutting to remove the glue. The remaining core is crushed and used for radioactive analysis to complete the dating calculation.We have 3 fully automated, computer operated Riso Minisys TL readers for measuring the TL.The total amount of The samples are heated and the data appears as a graph of TL against temperature, called a glow-curve.The samples are irradiated in the laboratory with a known radiation dose and heated to produce another glow-curve.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.
Luminescence dating (including thermoluminescence and optically stimulated luminescence) is a type of dating methodology that measures the amount of light emitted from energy stored in certain rock types and derived soils to obtain an absolute date for a specific event that occurred in the past.
The method is a direct dating technique, meaning that the amount of energy emitted is a direct result of the event being measured.
More detailed expert reporting according to specific client needs can be undertaken following prior agreement with the laboratory.
Such consultancy work which will be charged on the basis of a daily rate of £500 VAT.
The older the pottery, the more radiation it has absorbed and the brighter the pottery sample glows.
