The gamma spectrometer has been put into the sample hole see the lead going from the gamma spectrometer crystal to the control box. CS1 maint: K-feldspars optical response stimulation spectra". We then give our sand sample a range of laboratory radiation doses and measure the luminescence that each dose produces to develop a calibration curve.

Optically Stimulated Luminescence
Thomsen, K. A certain percent of the freed electrons become trapped in defects or holes in the crystal lattice of the quartz sand grain referred to as luminescent centers and accumulate over time Aitken, Usage of Cookies: Absolute dating Amino acid racemisation Archaeomagnetic dating Dendrochronology Ice core Incremental dating Lichenometry Paleomagnetism Radiometric dating Radiocarbon Uranium—lead Potassium—argon Tephrochronology Luminescence dating Thermoluminescence dating. Recent advances in OSL dating techniques for feldspar 23 may result in this becoming the preferred mineral for OSL dating of glacial sediments, although feldspars are often more severely affected by partial bleaching than quartz.
