Aliko Biología NORMs Kosovo Fly Ash Exposure Concrete Kosovo thermal power plants (TPP) produce annually more than 1 million tons of fly ash as a byproduct of lignite combustion. The focus of this study was the characterization of activity concentration of natural radionuclides of hardened concrete specimens. The measurements were done with Hyper Pure Germanium gamma-ray spectrometry (HPGe). Concrete mixtures with different content of fly ash as cement replacement were prepared. Four concrete mixes with 15, 20, 25 and 30% fly ash replacing the respective content of cement were tested for activity concentration of 40K, 226Ra and 232Th, activity concentration index, indoor specific and annual absorption dose rate. The obtained results were compared to reference concrete mixtures without fly ash-standard concrete. The results of measurements in six concrete mixtures showed that the activity concentrations of 40K, 226Ra and 232Th were very low in all concrete specimens. 2018 artículo científico 2319-0612 https://www.redalyc.org/articulo.oa?id=722280820002 en http://www.redalyc.org/revista.oa?id=7222 Brazilian Journal of Radiation Sciences application/pdf Sociedade Brasileira de Proteção Radiológica - SBPR Brazilian Journal of Radiation Sciences (Brasil) Num.1 Vol.6 |
