ASPECTS OF RETROSPECTIVE ESR DOSIMETRY

A review is given on the major technological and methodological aspect s of retrospective ESR dosimetry with tooth enamel. Topics include the collection and preparation of samples, the evaluation, treatment and interpretation of the ESR signals, and the procedure of dose-reconstru ction, Two pathways are described to differentiate between doses from different internal and external sources. They are based on dose compar isons as evaluated from different tooth tissues or from dose vs age de pendencies obtained by ESR dosimetry from populations with different e xposure conditions. The concepts given are illustrated by recently ach ieved ESR doses that were reconstructed from teeth of radiation worker s and members of the public of the Southern Urals region, Russia.
