“…The luminescent material in tooth enamel and dentin is hydroxyapatite and in order to eliminate the chemiluminescence effect the material has to be deproteinated, for example using NaOH (Kolberg et al, 1974). The difficulties with chemiluminescence and the necessity for deproteination, however, led GodfreySmith and Pass (1997) to try a non-heating method, namely OSL.…”

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...

“…ESR can be used to measure the absorption of electromagnetic (microwave) radiation by these free radicals. The magnitude of this absorption is proportional to the number of free radicals and thus gives a measure of absorbed dose (4,5,7,8,10,39 is not destroyed by ESR measurements, as is the case with thermoluminescence (TL) dosimetry (40)(41)(42).…”

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.
