Neutron activation analysis of ceramic tiles and its component and radon exhalation rate

Abstract： The concentrations of 20 trace elements in several ceramics tiles and ceramic composites used in Egypt were elementally analyzed by neutron activation analysis(NAA) technique. The samples and standard were irradiated with reactor for 4 h( in the Second The gamma-ray spectra obtained were measured for several times by means of the hyper pure germanium detection system( HPGe).Also a solid state nuclear track detector(SSNTD) CR-39, was used to measure the emanation rate of radon for these samples. The radium concentrations were found to vary from 0.39-3.59 ppm and the emanation rates were found to vary from (0.728-5.688) x 10-4The elemental analysis of the ceramic tiles and ceramic composites have a great importance in assigning the physical properties and in turn the quality of the material. 作 者： A.El-Shershaby    A.Sroor    F.Ahmed    A.S.Abdel-Haleem    Z.Abdel   作者單位： A.El-Shershaby,A.Sroor,Z.Abdel(Nuclear Physics Laboratory, Faculty of Women, Ain-Shams University, Cairo, Egypt)
