摘要

Novel building materials were manufactured and analyzed for ~(226)Ra, ~(232)Th and ~(40)K using an HPGe gamma-ray spectrometer. The results show that the highest value of ~(40)K was 4530 Bq per kg which was measured in a sample containing fly ashes from olive stones. The highest values of ~(226)Ra and ~(232)Th activities were 181 and 185 Bq per kg, which were measured in a sample with fly ashes from the co-combustion of coal and coke, respectively. On the other hand, the lowest values of ~(40)K, ~(226)Ra and ~(232)Tb activities were obtained for samples incorporating mussel shells. The radiological health hazard parameters, such as radium equivalent activity (Ra_(eq)), activity concentration index (I), absorbed and effective dose rates, associated with these radionuclides were evaluated. These values are within the EU recommended limits in building materials, except for samples of concrete containing fly ashes from olive stones, coal and coke. This study has contributed to the inclusion of industrial wastes that have not been collected previously in the Naturally Occurring Radioactive Material (NORM) databases on radioactivity of building materials.
