“…In such situations, a quick and simple sampling method followed by a fast identification of the absorbed dose is needed for the triage of the victims and for planning an appropriate medical treatment of those exposed (Trompier et al 2017). Human tissues, such as tooth enamel and bone, already proved to be useful in ex vivo EPR dosimetry (Trompier et al 2009b; Fattibene and Callens 2010; Krefft et al 2014; Kaminska et al 2016; Kinoshita et al 2018). However, their applicability is limited due to the obvious difficulty in sample acquisition.…”

In this study, samples of smart phone touch screen glass sheets and tempered glass screen protectors were examined with respect to their potential application in the dosimetry of ionizing radiation. The glass samples were obtained from various phones with different types of glass. Electron paramagnetic resonance (EPR) spectra of the radiation-induced signals (RIS) are presented and their dose dependence within a dose range of 0–20 Gy. Despite the observed fading with time of the dosimetric components of the signal, the remaining RIS turned out to be strong enough for a reliable dosimetry even 18 month after irradiation. The study also shows that crushing of the glass sheets and water treatment of the samples have no effect on the background and dosimetric EPR signals.

“…The radiation-induced signal is stable and has the form of singlet, which shows axial symmetry features (g ┴ = 2.003 and g ║ = 1.997) both in X and Q-band EPR measurements (Strzelczak, Sadło, Danilczuk, Stachowicz, Callens, Vanhaelewyn, Goovaerts & Michalik, 2007). The linear RIS dependence on the absorbed dose was observed up to 180 Gy (Krefft, Drogoszewska, Kaminska, Juniewicz, Wołąkiewicz, Jakacka & Ciesielski, 2014).…”

The electron paramagnetic resonance measurements of dosimetric signals originating from radicals generated under the influence of ionizing radiation allow to determine the dose absorbed by the casualties of radiation accidents. The study material can consist of victim’s teeth, bones or nails. Also human hair and mineral glass from personal electronic devices, that people had in the moment of accident, are considered to be useful in dosimetry. Although X-band (9.4 GHz) spectrometers predominate, Q-band devices (34 GHz) enable to increase the sensitivity of measurements and reduce the size of specimens, whereas L-band machines (1.1 GHz) are suitable for in vivo dosimetry. The EPR tooth enamel dosimetry has been used many times to assess the cumulative radiation dose and health risk in people living in areas contaminated due to the radiation accidents and to determine the unknown absorbed doses in patients after the overexposures during radiotherapy treatment.

“…EPR techniques have been applied to bone for the dosimetry of patients undergoing radiotherapy (e.g., Krefft et al, 2014) but it has also been used to assess the radiotherapy doses received in cases of accidental overexposure. An example of the latter application was described by Trompier et al (2007a) in which the authors examined pieces of rib bone removed from breast-cancer patients who had each experienced over-exposure (60-80 Gy) during radiotherapy, caused by faulty equipment.…”

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...
