| Abstract:: |
| Objective To study the influences of different sample preparation methods on tooth enamel ESR signals in order to reduce the effect of dentine on their sensitivities to radiation. Methods The enamel was separated from dentine of non_irradiated adult teeth by mechanical,chemical,or both methods.The samples of different preparations were scanned by an ESR spectrometer before and after irradiation. Results The response of ESR signals of samples prepared with different methods to radiation dose was significantly different. Conclusion (The selection) of sample preparation method is very important for dose reconstuction by tooth enamel ESR dosimetry,especially in the low dose range. |
