Jan 13, 2020 In experiments carried out with quartz in the sand grain size, the OSL sensitivity calculation applied normalization by dose and aliquot mass (photon cts Gy −1 mg −1). In the first experiment, OSL sensitivity was also calculated as a percentage of the initial 1 s of light emission in relation to the total OSL emission (%BOSL).
