Development of high sensitive LiNaSO4:Cu,Mg phosphor for TLdosimetry

► Mg co-doped LiNaSO4:Cu is found to be a very sensitive TL material for gamma-rays irradiation. ► The glow peak around 160 °C in LiNaSO4:Cu,Mg is well defined as a dosimetric peak. ► LiNaSO4:Cu,Mg has been found to have simple and sharp glow peak. ► LiNaSO4:Cu,Mg has good linearity in TL vs. dose response, excellent TL sensitivity.
