It is especially conceived for dating application in thermoluminescence analyses.Hi Vo is a device especially conceived to furnish an adjustable elevated voltage up to 2.000V.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.Luminescence dating is particularly appropriate when radiocarbon dating is not possible (either where no suitable material is available or for ages beyond the radiocarbon age limit) or for applications affected by radiocarbon plateau effects ( 1700 AD, early Iron Age contexts, late glacial timescales) and when the relationship between the organic materials and the archaeological context is uncertain.

When we receive your sample we must first prepare it for measurement.During its lifetime the pottery absorbs radiation from its environment and it is this which creates thermoluminescence.The older the pottery, the more radiation it has absorbed and the brighter the pottery sample glows.Radiocarbon WEB-info Provides a large international listing of laboratories that do radiocarbon dating; information on radiocarbon dating; publications and references; and educational materials. The Smithsonian Institution, Museum Conservation Institute (MCI), gives no endorsements for any products, materials or services mentioned in this pamphlet and is not responsible for problems from their use or misuse.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.
