Resumo
Beryl is a silicate with chemical formula Be3Al2(SiO3)6 commonly found in Brazil. It has a few
colored variations used as jewelry, like Aquamarine (blueish), Emerald (green) and Heliodor (yellow). In this
work, Heliodor pellets of 5 mm diameter and 1 mm thickness have been produced and investigated using
thermoluminescence (TL) to evaluate its potential for use as gamma ray’s dosimeter. The results show that
the pellets exhibited a prominent TL peak at 205 °C that grows linearly with dose when irradiated from 1
Gy to 1000 Gy. Deconvolution of the TL peaks was carried out using CGCD (Computerized Glow Curve
Deconvolution) method. The peak positions were determined using the Tm/Tstop method described in
McKeever (1985). Samples were stored in dark room at room temperature for 21 days to evaluate the
fading of the TL signal, the main TL peak at 205 °C did not show any decrease in intensity.
