“…A factory-produced metering container containing 20 dosimeters per batch was used for the calibration and determination of the TL response per m rad (Kellerer, Hahn, & Rossi, 1992). A full batch of dosimeters was annealed for 1 h at 400 degrees Celsius, followed by 2 h at 100 0 C (Al-Salihi et al, 2021;Alfahed et al, 2019;Bdran et al, 2020;Bujdosó, 1987;Ramadhan, Al-Salihi, & Khalaf, 2020). This treatment also improves the dosimeter's sensitivity.…”
