Resumo
Radiation dosimetry demands a continuos innovation in materials development. Yttria (Y2O3) exhibits intrinsic
lattice features that enable doping with other rare-earth ions, resulting in improvement of its solid state characteristics. This work aims to evaluate thulium (Tm) effect on promotion of dose-response behaviour of yttria
(YTm) rods by Electron Paramagnetic Resonance (EPR). YTm rods were irradiated with gamma (
60Co) doses from
0.001 to 150 kGy and evaluated by EPR, with an X-band EPR, and at room temperature. According to results,
YTm rods exhibited a linear dose-response behaviour in a range of dose from 0.001 to 1 kGy. In addition, the
fading of EPR signal during 288 h was achieved up to 88 %. These findings indicate that thulium-yttria is a
promising material for radiation dosimetry.
