“…The possibility to use table sugar for retrospective EPR dosimetry was investigated by Nakajima (1988), Nakajima and Otsuki (1990), Trivedi and Greenstock (1993), Fattibene et al (1996) and others. Tchen et al (1993) examined different binders for sucrose pellets production and determined that 40% of sucrose in an inert silicone elastomer allow to measure doses in the range 0.5-10 Gy with a standard uncertainty 74%.…”

“…Several efforts have examined the EPR signal from various sugars and quite an extensive literature exists (e.g., Trevedi and Greenstock, 1993, Fattibene et al, 1996, Yordanov and Georgieva, 2014, Da Costa et al, 2005, Hervé et al, 2006and Desrosiers and Wadley, 2006. However, as pointed out by Trompier et al (2010a), the availability of sugar as a personal emergency dosimetry material is limited due to the unlikelihood that individuals would routinely carry such materials.…”

“…Trevedi and Greenstock (1993) attempted to use the EPR signals from hair in this manner but the radiation-induced signals were confounded by a high non-radiation induced background, possibly related to mechanical effects similar to those observed by Chandra and Symons (1987), but also possibly related to melanin (Çolak and Özbey, 2011). Melanin, as has been shown by Strzelczak and others (Strzelczak et al, 2013) generates an EPR signal following exposure to sunlight.…”

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...

“…Hair is composed mainly of alpha keratin same like fingernails, however its use as accidental dosimeter is limited because of the melanin pigments (Trivedi, A., and Grenstock, C., 1993). Some attempts were performed to study different hair types, with different pigments, but it was found that hair EPR signal exhibit some complexities that limit its use in dose evaluation.…”
