Modifications in the synthesis procedure of calcite involve statistically significant changes in the relative intensities of the EPR lines of the irradiated samples. Of the 6 (or 8) paramagnetic centres produced by γ- (or α-) irradiations, four are

L-band (similar to 1 GHz) EPR has the potential to measure the absorbed radiation dose in human teeth inside the mouth (in vivo analyses). One crucial point in the development of the method is to know if dosimetry evaluation carried out in vivo after

L-band EPR measurements were done in vitro on extracted human teeth with the objective to evaluate the feasibility of retrospective in vivo EPR dosimetry. In a recent study, the relative contributions of individual tooth components (enamel, crown den

Regarding in vivo L-band dosimetry with human teeth, a number of preliminary experiments were carried out that were linked to the resonators response and the relative contribution of enamel to the EPR signal intensity of irradiated whole teeth. The s

Recently, we have participated in 'The 2nd International Intercomparison on EPR Tooth Dosimetry' wherein 18 laboratories had to evaluate low-radiation doses (100-1000 mGy) in intact teeth (Wieser et al., Radiat. Meas., 32 (2000a) 549). The results of

The detection of glass particles in glass-induced injuries is often difficult. Most commercial glasses contain iron (Fe3+) centers which present a characteristic electron paramagnetic resonance (EPR) spectrum nearg = 4.3. The detection of small glass

A natural monohydrocalcite sample from Australia was submitted to gamma -irradiations and analysed by TL and ESR. Spurious TL signals are observed, probably due to the presence of water and organic impurities. TL and ESR dose response curves are pres

Enamel from 6 different positions in a well preserved elephant tooth from the Karlich-Seeufer site in Germany has been irradiated up to 32 kGy. The X-band (v = 9.5 GHz) ESR spectra of two subsamples have been decomposed into three real components wit
