EPR dosimetry of the enamel based on measurement

concentrations of stable radicals formed under the influence of

ionizing radiation. The method allows to estimate the total absorbed

radiation dose in the enamel of the teeth, accumulated over the lifetime of the donor

(before the extraction of the tooth) , including the impact of both anthropogenic

and natural radiation sources. Thus , ESR dose

necessarily contains a background component. The task of reconstruction

background doses is complicated by the fact that the background levels are close to the EPR dosimetry detecting limit , so the uncertainty of each

individual measurement is comparable to the variability of individual

doses in the population. The report is based model, which allows to reconstruct the basic parameters of background doses from measurements of radionuclide content in the enamel of the teeth donors.
