Abstract: Barium sulphate doped with Pr (0.27 mol%) has been synthesized by chemical methods. Thermoluminescence (TL) glow curves of BaSO4:Pr sample annealed at different temperatures 620, 670, 720, 770 and 820 K, respectively have been recorded after irradiation with X-rays. The observed TL glow curves show a prominent peak at Tm (=436-440) K and two daughter peaks at temperatures (388-399) and (469-477) K, respectively. The dose response curves of the sample annealed at 770 K for 1 h after Tc=450 K is also recorded. Trapping parameters of observed glow curves can be calculated by conventional techniques.
