Abstract

This paper presents the characterization and TL properties of dysprosium (Dy) doped calcium sulfate (CaSO 4 ) TL material produced by co-precipitation technique with 0.5mol% concentration of dopant. The morphology of the produced TL material was studied using scanning electron microscope (SEM) and the micrograph shows that rectangular parallelepiped shaped crystal with the average of 150 μm in length were produced. The crystallinity of the produced powder was studied using x-ray powder diffraction (XRD). The XRD spectra show that the TL material produced is high purity anhydrite CaSO 4 with average crystallite size of 74 nm with orthorhombic crystal system. The TL behavior of produced CaSO 4 : Dy was studied using a TLD reader after exposure to gamma ray by Co 60 source with the doses of 1,5 and 10 Gy. The glow curve shows linear response with glow peak around 230°C which is desired development in the field of radiation dosimetry.
