“…Property of the TL signal shows that the sample is bent of producing high stability free radicals by radiation under room temperature. However, it is necessary to carry out additional research to investigate whether the deproteinization treatment with hydrazine preserves the radiation-induced TL signal [10,21]. In addition, annealing may be performed on the sample.…”

In this study; Thermoluminescence(TL) properties of tooth enamel which was obtained from health teeth in the Faculty of Dentistry Ege University was investigated. The tooth enamel was exposed to X-ray and TL spectra were taken with different heating rates (β) (2-10 o C/s). It was observed that there is a broad TL peak approximately at 210 o C for tooth enamel in the range of 50-400 o C. The dependence of heating rate and exposed X-ray dose (dose response) of the 210 o C peak were investigated, as well as kinetic parameters were calculated using peak shape and heating rate methods for tooth enamel.

“…Yukihara et al (2007) followed up this observation using a high-sensitivity OSL reader and were able to measure IR-, greenand blue-light-stimulated OSL from undeproteinated teeth, with a minimum detection limit of 4-6 Gy. Further developments by Godfrey-Smith, 2008and Yüce et al (2010 pushed the MMD to as low as 1.5-4 Gy, approaching the limits required for triage. However, these results were only obtained on extracted, deproteinated teeth using high-sensitivity apparatus and blue stimulation.…”

HIGHLIGHTSReview of the use of luminescence and electron paramagnetic resonance in retrospective and emergency dosimetry.Optically stimulated luminescence (OSL), thermoluminescence (TL) and Electron Paramagnetic Resonance (EPR) results on biological and physical materials.Descriptions of use in emergency and retrospective dosimetry, following large-scale radiological events.http://www.sciencedirect.com/science/article/pii/S1350448716302359 ABSTRACTThis paper reviews recent research on the application of the physical dosimetry techniques of electron paramagnetic resonance (EPR) and luminescence (optically stimulated luminescence, OSL, and thermoluminescence, TL) to determine radiation dose following catastrophic, large-scale radiological events. Such data are used in dose reconstruction to obtain estimates of dose due to the exposure to external sources of radiation, primarily gamma radiation, by individual members of the public and by populations. The EPR and luminescence techniques have been applied to a wide range of radiological studies, including nuclear bomb detonation (e.g., Hiroshima and Nagasaki) nuclear power plant accidents (e.g., Chernobyl), radioactive pollution (e.g., Mayak plutonium facility), and in the future could include terrorist events involving the dispersal of radioactive materials. In this review we examine the application of these techniques in 'emergency' and 'retrospective' modes of operation that are conducted on two distinct timescales. For emergency dosimetry immediate action to evaluate dose to individuals following radiation exposure is required to assess deterministic biological effects and to enable rapid medical triage. Retrospective dosimetry, on the other hand, contributes to the reconstruction of doses to populations and individuals following external exposure, and contributes to the long-term study of stochastic processes and the consequential epidemiological effects. Although internal exposure, via ingestion of radionuclides for example, can be a potentially significant contributor to dose, this review is confined to those dose components arising from exposure to external radiation, which in most studies is gamma radiation.The nascent emergency dosimetry measurement techniques aim to perform direct dose evaluations for individuals who, as members of the public, are most unlikely to be carrying a dosimeter issued for radiation monitoring purposes in the event of a radiation incident. Hence attention has focused on b...

Abstract:In this paper, the infrared stimulated luminescence (IRSL) property of naturally corroded aluminum and its possible applications in retrospective dosimetry have been briefly studied. Results are interesting, in particular with regard to the efforts of finding new and widely available materials for accident dosimetry. For aluminum corrosion, the dose response was found to be approximately linear between 2-80 Gy and to reach saturation before 300 Gy. The signal also showed good reproducibility without significant fading over storage durations of up to four mounts at room temperature. In addition to the luminescence, the corrosion samples were also analysed by X-ray Fluorescence (XRF) and X-ray Diffraction (XRD), but conclusive identification of the luminescent phase could not be made. It is concluded that the IRSL signals of this material can be favourable for dosimetry research.
