Assessment of Dose with CaF₂ OSL Detectors for Individual Monitoring in Radiodiagnostic Services Using a Developed Algorithm Based on OSL Decay Curve

OSL and TL are luminescent techniques used for individual monitoring for the assessment of doses. Calcium fluoride (CaF₂) detectors are successfully applied for personal dosimetry combined TL technique. Studies published in the last years highlight the dosimetric properties of this material with the OSL technique. Considering the advantages of OSL in personal dosimetry and luminescent properties of CaF₂ detectors, in this work we developed an algorithm method for evaluation of operational quantity H_p(10) with CaF₂ detectors used by workers exposed to radiation energy range find in radiodiagnostic services. A blind test with CaF₂ detectors was performed. The analysis of H_p(10) results using the trumpet curve criteria was performed for both setups of energy range of x-ray photon beam. In both blind tests, the criteria of the trumpet curve were fulfilled, demonstrating the applicability of CaF₂ detectors with the OSL technique, as the developed algorithm, in radiation monitoring for workers at diagnostic imaging services.
