Turnaround time is several weeks to several months and very dependent on the time taken to prepare the samples, with organic rich samples taking the longest. All sediments contain trace minerals including uranium, thorium and potassium.
These slowly decay over time and the ionising radiation they produce is absorbed by other constituents of the sediments such as quartz and feldspar.
The basic cost is £550/sample plus reporting time based on your requirements.
The report will contain OSL results calibrated for sample water content and salinity.
Luminescence Dating Laboratory Department of Geography University of Georgia GGY Building, Room 3AS Athens, GA, 30602-2502 Phone : 706-542-2322/2354 FAX : 706-542-2388 Director: George A. Brook WEBSITE: University of Georgia Luminescence Dating Laboratory began operations in early 2002.
The lab has produced more than 300 OSL ages (from 140 years to 120,000 years) for aeolian, fluvial, lacustrine, and marine sediments, as well as pottery, artifacts and secondary carbonate.
The error limits on the dates obtained are typically in the range of 5 to 10%.
Commercial dating service For over 15 years the laboratory has undertaken luminescence dating of archaeological materials and sediments on a commercial basis or research basis.
Our standard cost for TL or OSL dating is 650 euro VAT per sample but prices can vary depending on the nature and number of samples.
Including fieldwork and radioactivity measurements, sample collection.
Stimulating samples using infrared light causes luminescence, the intensity of which varies depending on the amount of radiation absorbed.
Exposure to sunlight resets the luminescent signature and so the time period since the sediment was buried can be calculated.
Age range and precision The age range for pottery and other ceramics covers the entire period in which these materials have been produced.
