“…Due to the operations of Mayak PA, the environment around the plant, and especially around the near Techa River, became contaminated (Degteva et al, 1994;Balonov et al, 2006). It is estimated that more than 25,000 residents of the region might have been exposed to radiation due to discharges of radioactive waste into the Techa River.…”

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.

“…External exposures to g-radiation were primarily from 137 Cs, with some additional exposure from 106 Ru, 95 Zr. Internal exposures largely resulted from use of river water contaminated with 137 Cs, 89 Sr, and 90 Sr for drinking, cooking and other domestic needs (Degteva et al, 1994). Details of the Techa River Dosimetry System (TRDS-2000) used to reconstruct external and internal doses are published elsewhere (Degteva et al, 2000a, b;Jacob et al, 2003).…”

“…About 95% of the total activity was released into the Techa River from March 1950 through November 1951. The primary radionuclides released were 137 Cs and the bone-seeking isotopes of strontium ( 89 Sr and 90 Sr), which accounted for 12.2 and 20.4% of the total discharge, respectively (Degteva et al, 1994).…”

Breast cancer incidence following low-dose rate environmental exposure: Techa River Cohort, 1956–2004

In the 1950s, the Mayak nuclear weapons facility in Russia discharged liquid radioactive wastes into the Techa River causing exposure of riverside residents to protracted low-to-moderate doses of radiation. Almost 10 000 women received estimated doses to the stomach of up to 0.47 Gray (Gy) (mean dose ¼ 0.04 Gy) from external g-exposure and 137 Cs incorporation. We have been following this population for cancer incidence and mortality and as in the general Russian population, we found a significant temporal trend of breast cancer incidence. A significant linear radiation dose -response relationship was observed (P ¼ 0.01) with an estimated excess relative risk per Gray (ERR/Gy) of 5.00 (95% confidence interval (CI), 0.80, 12.76). We estimated that approximately 12% of the 109 observed cases could be attributed to radiation.

“…This correct dose was computed as an average of the collective biological dosimetry, with weights based on variances of the measurements for each technique. In this regard, the present study works toward the goal of collective dosimetry for dose reconstruction (16,27,29,82,83). However, comparisons in the scientific literature between biological and physical methods of radiation dosimetry remain infrequent (80,(84)(85)(86).…”

“…However, it provides no information about biological impact; it is not a direct measure of whole-body dose; and it is subject to confounding factors such as the effect of ingested P-emitters (28)(29)(30). The problem of intersample variability in sensitivity to radiation must also be addressed (31).…”

Collective Radiation Biodosimetry for Dose Reconstruction of Acute Accidental Exposures: A Review

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.
