P-3a-211 1 Interlaboratory Comparison of EPR Dose Reconstruction Results for Russian Nuclear Workers

Electron paramagnetic resonance (EPR) in human tooth enamel is a powerful tool for individual dose reconstruction. This method is based on EPR measurements of the concentration of stable (~107 yr.) radiation induced radicals in the mineral component of tooth enamel. In spite of the growing number of the publications devoted to this method (see, for example, [1-5]) there are still some uncertain issues regarding its performanc
