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. This effect was explained by Christiaan Huygens 1629 1695 Dutch physicist as double refraction of what he called an ordinary and an extraordinary wave With the help of a polarizer we can easily see what these ordinary and extraordinary beams are Ob 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.
