| description: | 1. Investigation of regularities in the types and concentration of radiation defects in tooth enamel with thermal treatment. 2. Distinguishing of processes caused by diffusion of defects over the activation barrier. 3. Describe selected processes seen in the spectra with an Arrhenius type plot. 4. Improve the reliability of the EPR method in geological dating based on tooth enemel and other bone artefacts. |
