ESR dosimetry of optically bleached quartz grains extracted from Plio-Quaternary sediment: Evaluating some key aspects of the ESR signal associated to the Ti-center

Duval, Mathieu; Guilarte, Veronica


Abstract The present study aims at investigating several key aspects of ESR dose reconstruction of quartz grains based on the analysis of the Ti-center: (i) the evaluation of the ESR intensity, (ii) its impact on measurements precision, and (iii) the potential of various fitting functions to describe the behavior of the signal with the radiation absorbed dose. In contrast with the Al center, the various Ti centers have quite low ESR signal intensities. It is thus crucial to adapt the...[Show more]
