Effects of ionizing radiation of different types of optically stimulated luminescence

Optically Stimulated Luminescence (OSL) is the luminescence emitted by an irradiated insulator or semiconductor during exposure to visible light. The OSL intensity is a function of THA radiation dose absorbed by the sample and this can be used as the basis of a radiation dosimetry system.Al2O3:C is one of the materials that is used widely in dosimeter applications. In this study, the dose reactions of Al2O3:C which is used as an OSL dosimeter commonly to various nuclear radiation ranges are examined. Al2O3:C tablets were exposed to alpha, beta particles and gamma photons and blur light-emitting diode (LED); then, the stimulated luminescence counts were absorved. In experiments of alpha (226Ra) and gamma (137Cs) the point sources were used. In x-ray experiments, Linac at the Department of Radiotheraphy at Atatürk Chest Surgery Training and Research Hospital was used and 90Sr-90Y sources were used in experiments of beta particles. The measured luminescence decay curves were analyzed by comparing.?
