Concentrations of Natural Radionuclides in Imported Zirconium Minerals
Апстракт
The natural radioactivity in imported zircon samples used as glaze for ceramic tiles in the ceramics industry has been presented in this paper. The measurements were made by gamma spectrometry with a high purity germanium detector. The average activity concentrations of (238)U and (232)Th determined in the measured samples (3250 Bq/kg, and 556 Bq/kg, respectively) are much higher than the concentrations found in the Earths crust. The activity concentration of (226)Ra is also high in all analyzed samples, while (40)K was not detected. The gamma index, I, the external hazard index, H(ex), the internal hazard index, H(in), and the radium equivalent activity, Ra(cg), were calculated. Due to relatively high activity concentration level of uranium in imported zircon samples, specific regulations are necessary for zircon compound used in ceramic industry. It can be concluded that the investigated samples can be used as the component of ceramic glaze in the concentrations not above 3%.
