摘要：
Recently, Mg-phosphate ceramics have represented good biocompatibility and bioresorbability which made them promising materials in the biomedical applications. A different application was suggested for the use of these ceramics as a thermoluminescent dosimeter. This study was aimed at the investigation of thermoluminescence (TL) properties of Mg-phosphate bioceramic and discussed the feasibility of this material for radiation dosimetry applications in a high dose. The synthesized ceramic was investigated using XRD, HR-TEM and FTIR. The results showed that the prepared Mg-phosphate ceramic particles were in the nanoscale, and the main formed crystalline phases were farringtonite, (Mg-3(PO4)(2)), and periclase (MgO). Moreover, TL measurements demonstrated that TL-glow curve of Mg-phosphate showed three peaks at 387 K, 478 K and 560 K. Dose-response investigations showed that magnesium phosphate has a linear dose-response from 5 Gy up to 1 kGy. No significant fading was observed after 60 days of normal storage.
