In this research work, hydroxyapatite samples doped with cerium, gadolinium, and a combination of these two dopants were synthesized through the hydrothermal method. MAUD code, a material diffraction analysis software based on the Rietveld method, was used to investigate the formed crystal phases in synthesized samples. The thermoluminescence dosimetry response of the samples was investigated, and the results showed that the thermoluminescence response of the sample doped with the compound dopants is the median level of the thermoluminescence response of the samples doped with one dopant. It was found that adding cerium dopant could improve the thermoluminescence response of the sample doped with gadolinium. Also, the results of Rietveld refinements showed that the formed phases of hydroxyapatite could affect the thermoluminescence dosimetry response.
