“…The isolated "pure" dosimetric signal can be obtained by subtraction of a native reference spectrum or of a simulated native signal obtained from the original spectrum (see, e. g., Skvortzov et al, 1995;Shimano et al, 1989;Hayes et al, 1997;Sholom et al, 2000a). This method may seem more straightforward than spectrum modelling, but only at first glance.…”

When tooth enamel is exposed to ionizing radiation, radicals are formed that can be detected using Electron Paramagnetic Resonance (EPR) techniques. EPR dosimetry using tooth enamel is based on the (presumed) correlation between the intensity or amplitude of some of the radiation-induced signals with the dose absorbed in the enamel. In the present paper a critical review is given of this widely applied dosimetric method.The first part of the paper is quite fundamental and deals with the main properties of tooth enamel and several of its model systems (e.g., synthetic apatites). Considerable attention is also devoted to the numerous radiation-induced and native EPR signals, and the radicals responsible for them. The relevant EPR detection, identification and spectrum analysing methods are reviewed from a general point of view. Finally, the need for solid state modelling and the linearity of the dose response are investigated.The second part is devoted to the practical implementation of EPR dosimetry using enamel. It concerns the preparation of samples, specific irradiation problems, spectrum acquisition and it is described how the dosimetric signal intensity and dose can be retrieved from the EPR spectra. Special attention is paid to the energy dependence of the EPR response and to sources of uncertainties. Results of and problems encountered in international intercomparisons and epidemiological studies are also dealt with.In the final chapter the future of EPR dosimetry with tooth enamel is analysed.

“…The basis of retrospective EPR dosimetry techniques also originated in the 1960s with the pioneering work of Swartz and colleagues (Swartz, 1965 andBrady et al, 1968) who observed stable radiation-induced EPR signals in calcified tissues exposed to ionizing radiation doses. EPR tooth dosimetry research started to grow rapidly after the Chernobyl accident in 1986 (Aldrich and Pass, 1988, Shimano et al, 1989and Ikeya and Ishii, 1989, which resulted in maturation of the EPR technique with tooth enamel. The technique has been verified through several intercomparisons (Chumak et al, 1996, Wieser et al, 2000a and was applied for dose reconstruction of A-bomb victims (Ikeya et al, 1984 andNakamura et al, 1998), Chernobyl liquidators , the population in territories contaminated due to the Chernobyl accident (Skvortzov et al, 1995, Skvortzov et al, 2000, Ivannikov et al, 1997, Ivannikov et al, 2004band Ivannikov et al, 2014, residents near the Semipalatinsk Nuclear Test Site (SNTS, Kazakhstan) , Zhumadilov et al, 2009, Zhumadilov et al, 2011a, Zhumadilov et al, 2011b, Zhumadilov et al, 2013Ivannikov et al, 2002, Pivovarov et al, 2002and Sholom et al, 2007a, and the inhabitants of the Techa River basin affected by the operation of the Mayak Production Association , Degteva et al, 2005, Degteva et al, 2015.…”

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...

“…Separation of the contributions from diagnostic X-rays and high energy y rays to the ESR signal in dental enamel and proper account of the mass-energy attenuation coefficient were investigated by Aldrich and Pass (18) and then elaborated on by other groups (53)(54)(55). This separation uses the dependence of attenuation of absorbed dose across the width of a tooth on energy of the incident radiation.…”

Quantification of the biologically relevant dose is required to establish cause and effect between radiation detriment or burden and important biological outcomes. Most epidemiologic studies of unanticipated radiation exposure fail to establish cause and effect because researchers have not been able to construct a valid quantification of dose for the exposed population. However, no one biodosimetric technique (biophysical or biological) meets all the requirements of an ideal dosimeter. This paper reviews how the collection of biodosimetric data for victims of radiation accidents can be used to create a dosimetric "gold standard." Particular emphasis is placed on the use of electron spin resonance, a standard for radiation accident dosimetry. As an example of this technique, a review will be presented of a previously reported study of an individual exposed to a 60Co sterilization source.
