Radioactivity is mainly due to natural ones from earth and also from outside of the atmosphere so-called cosmic radiation. Although radiation sources and their dose effect on humans are known, there is still some conflict on their health effect especially on dental restoration. The limited data for radioactive dental materials and their potential risks for patient makes those materials interesting to be investigated. For this purposes, uranium, thorium and potassium activity have been measured in some dental restorative materials, such as resin composites containing silica and zirconia particles as filler loading, using gamma spectrometer system with NaI(Tl) detector.
