Ceramic tiles are one of the commonly used decorative building materials. Body of ceramic tiles is a mixture of\uddifferent raw materials including clays, quartz materials and feldspat, and may be glazed or left unglazed. Due\udto the presence of zircon in the glaze, ceramic tiles can show natural radioactivity concentration significantly\udhigher than the average values for building materials. This study presents a summary of results obtained by a\udsurvey which was consisted of measurements of activity concentrations of natural radionuclides in imported\udceramic tile samples used in Serbia using a gamma spectrometer with HPGe detector. Based on the obtained\udconcentrations, gamma index, radium equivalent activity, the indoor absorbed dose rate and the corresponding annual effective dose were evaluated to assess the potential radiological hazard associated with these\udbuilding materials
