PPT-Optically Stimulated Luminescence (OSL)

Measures time since mineral grains were buried last exposed to sunlight Trace amount of radioactive isotopes K U Th Rb slowly decay over time Produced ionizing radiation absorbed by mineral grains usually quartz as charge called electron trap. wallingairitudelftnl Phone 31 015 278 1056 Fax 31 015 278 9011 Abstract Abstract Abstract Abstract Abstract Optically stimulated luminescence OSL dating is a quantitative dating method to determine the time of last exposure of sand and silt to sun li Based on optically stimulated luminescence OSL technology InLight dosimeters can be reanalyzed many times at your discretion because they retain dose information after analysis LANDAUER also makes available to you our exclusive automatic annealer 10.3.6.3.1 Classification of luminescence parametersThe luminescence property of an analyte as measured by the appropriate instrument will often be distorted by instrumental and sample effects, and th Luminescence Scienceand Display Materials Luminescence is Del neD BROADLY As THe γeneRATiOn OF LiγHT in eXcess OF THAT RADiATeD THeRmALLY.

As sediment [quartz] is transported by wind, water, or ice, it is exposed to sunlight (“bleached”) and zeroed of any previous luminescence signal. Once this sediment is deposited and subsequently buried, it is removed from light and is exposed to low levels of natural radiation from the surrounding . stemler. , Andy . Barrus. , Sean . Osinski.
