Resumo
Green quartz is usually studied for low dose TL dosimetry of gamma and X radiation. The aim of the present work
is the dosimetric characterization of natural green quartz in the dose range of 0.47 mGy up to 1000 mGy of
gamma and X radiation. Green quartz pellets were produced by cold pressing green quartz powder. The pellets
are very sensitive to gamma and X radiation with main prominent TL peak at 230 °C. The TL sensitivity of MTS-N
(LiF:Mg,Ti) and green quartz pellets were also compared. The dose response curve presented linear behavior in
the dose range studied. The glow curve was deconvoluted. Kinetic parameters such as trap depth, kinetic order
(b) and frequency factor (s) are determined. The TL photon energy dependence was also evaluated.
