Systematic studies are made on the CO2- signal in tooth enamel to improve the calculation of the absorbed dose D-E. They consist of experiments oil the effect of heating on the CO2- signal and the examination of the long-term development of the signals after irradiation and after heating experiments. Oil Suitable teeth both single- and multiple-aliquot methods were used to calculate an absorbed dose D-E. The peak to peak intensity of the CO2- signal shows ail enhancement within 3 days of irradiation. Furthermore a transient increase in the signal intensity after heating tooth enamel at 120degreesC is observed, which mostly fades within 10-20 days. After artificial irradiation it is necessary to wait at least 3 days before electron spin resonance (ESR) measurements can be done. Differences in signal growth curves obtained using, various protocols, for example single- or multiple-aliquot methods with and without heating after irradiation. are presented. Results for tooth enamel are compared with analogous experiments on the CO2- signal in carbonates.
