Addressing challenges in diagnostic X-ray dosimetry: uncertainties and corrections for AlO:C-based optically stimulated luminescent dosimeters.

The use of AlO:C-based optically stimulated luminescent dosimeters (OSLDs) in diagnostic X-ray is a challenge because of their energy dependence (ED) and variability of element sensitivity factors (ESFs). This study aims to develop a method to determine ED and ESFs of Landauer nanoDot™ OSLDs for clinical X-ray and investigate the uncertainties associated with ESF and ED correction factors. An area of 2 × 2 cm at the central axis of the X-ray field was used to establish the ESFs.
