Tooth enamel as a detector material for retrospective EPR dosimetry

Different methods of spectra evaluation and dose reconstruction in retrospective EPR dosimetry with tooth enamel have been compared in this study. Experiments with teeth irradiated with known doses have shown that dosimetry above 1 Gy using a dose effect curve is, with a standard deviation of 10%, the best method. As a second result it is shown that dosimetry down to 100 mGy with a standard deviation of 15% is possible.
