The thermoluminescence technique was employed to study bioglass matrix prepared using the traditional of glass making. synthesized were investigated X-ray diffraction (XRD), and differential thermal analysis (DTA) has been studied. highest thermoluminescent intensity found for composition 26.91 % CaO, 45.68 SiO2, 2.50 P2O5, 25.094 %Na2O (mol%), with only one glow peak at 460 k.
