Abstract: Thermally stimulated luminescence (TSL) of undoped and doped BaSO<sub>4 </sub>with activators such as Cu and Mn has been investigated. The polycrystalline samples of undoped and doped BaSO<sub>4</sub> are prepared by melting method. The formation of BaSO<sub>4</sub> compound is confirmed by X-ray diffraction (XRD) and Fourier transform infrared (FTIR) studies. Comparison of TL intensity of the most intensive glow peak of Cu doped BaSO<sub>4 </sub>compound with that of undoped BaSO<sub>4 </sub>shows that addition of Cu impurity in BaSO<sub>4</sub> compound enhances the TL intensity by about 9 times. However, the addition of Mn impurity to undoped BaSO<sub>4</sub> increases the TL intensity by about three times when compared with that of undoped BaSO<sub>4</sub>. Among the studied samples namely undoped, Cu and Mn doped BaSO<sub>4</sub>; Cu-doped BaSO<sub>4</sub> has been found to be the most sensitive.
