Preliminary report on the development of a virtually nondestructive additive dose technique for EPR dosimetry

We propose a new approach to the additive dose method in EPR dosimetry stud ies for tooth enamel specimens. We outline a specialized routine whereby th e sample may be left for the most part unirradiated, while only a small ali quot of the sample will be additively irradiated to relatively large doses. The routine is done in such a way so as not to significantly compromise ei ther precision or accuracy of the dose reconstruction. It is also demonstra ted that the overall throughput of the dose reconstruction is not appreciab ly compromised. With this potential ability, the utility of an internationa l dose/sensitivity standard for EPR dosimetry of teeth is considered. (C) 2 000 Published by Elsevier Science Ltd. All rights reserved.
