Abstract
We have previously demonstrated that the increased response of optically stimulated luminescence (OSL) compared to thermoluminescence (TL) following high ionization density (HID) alpha irradiation is naturally explained via the identification of OSL with the ”two-hit” F2 or F\(_3^+\) center, whereas the major component of composite TL glow peak 5 is believed to arise from a ”one-hit” complex defect. This discovery suggested that near-total discrimination between HID radiation and low ionization density (LID) radiation using combined OSL and TL measurements may have significant potential in mixed-field radiation dosimetry In this paper we discuss and compare the potential application of combined OSL/TL measurements using 6LiF:Mg,Ti (TLD-600) or 7LiF:Mg,Ti (TLD-700) and TLD-100 natural isotopic composition) detectors.
