Characterization of lithium diborate, sodium diborate and commercial glass exposed to gamma radiation via linearity analyses

Abstract

The linearity characteristic in radiation dosimetry presents a growing interest in medical physics. In this work, the lithium diborate, sodium diborate and commercial glass were irradiated with doses from 10 Gy to 10 kGy using a 60Co Gamma-Cell system 220, and then they were evaluated with the UV-Vis technique. The linearity analyses were applied through four methodologies, which the objetive to find linear regions in their response. The results show that all four analyses indicate linear regions for the studied radiation detectors. The samples with higher linearity range, in descending order, were lithium diborate, sodium diborate and commercial glass. In conclusion, the materials may be promising in dosimetry for intermediate and high doses of radiation.
