| Description: |
Results of wide-scale dose reconstruction with the use of EPR spectroscopy of tooth enamel are presented for the population living in the radioactive contaminated territories of Bryansk region of Russia. The population of radiation-free territories of neighboring Kaluga region was examined as the control group. The excess doses caused by radiation contamination were determined after subtraction of the contribution into EPR signal in tooth enamel due to the action of the natural background radiation during the lifetime of teeth. The average excess doses were determined for the groups of population formed according to the place of residence. The average values were determined with accuracy ranging from 4 to 25 mGy depending on the number of individuals included into the groups and on the scattering of individual results. The average excess doses highly varied for different places of residence and ranged up to 70 mGy. In general, the average doses of external exposure of the population obtained with EPR spectroscopy of teeth enamel were found to be consistent with the results based on other methods of direct dosimetry and retrospective dose reconstruction methods. Essential exceeding of the individual doses above the average level within the population groups was observed for some persons. That gave a possibility to detect the individuals with overexposure and to include them into groups of increased radiation risk for medical monitoring. |
