With support from the National Science Foundation, the University of Washington luminescence dating laboratory headed by Dr.James Feathers will purchase a Riso automated TL/OLS reader with automated processor which permits single grain luminescence determinations.We are open to suggestions of scientific collaboration as well as applications for funding for joint projects.Optically Stimulated Luminescence Dating precision accuracy in the optically stimulated luminescence dating sedimentary quartz.We perform OSL dating research using single aliquot regenerative (SAR) protocol on aeolian, fluvial, colluvial, and lacustrine sand.The ISGS OSL dating lab is equipped with a Risø TL/OSL-DA-20 Reader; Gamma Spectrometers; two amber light prep labs with fume hoods, shatter box, auto-grinding mortal, dry oven, and furnaces. Above Right: ISGS Risø TL/OSL-DA-20 Reader in dark lab Above Left: ISGS Gamma Spectrometry Lab.Including fieldwork and radioactivity measurements, sample collection.The typical turn-round time for providing a date is circa 2-6 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.
Age range and precision The age range for pottery and other ceramics covers the entire period in which these materials have been produced.
For artworks, it may be sufficient to confirm whether a piece is broadly ancient or modern (that is, authentic or a fake), and this may be possible even if a precise date cannot be estimated.
Radiation Exposure Dating Methods: Absolute dating by electron spin resonance (ESR), thermoluminescence (TL) , and optically stimulated luminescence (OSL) methods is widely applicable in geology, geomorphology, palaeogeography and archaeology.
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.
