For cements radioactivity estimation obtained by refinement of electrofilter ashes due to thermal power station from Oltenia coalfield was elaborated an estimation method. The method is based on radioactive index (RI) calculation for every component used at cement fabrication. The radioactive index was obtained by measurements of activities concentrations for 226Ra, 232Th and 40K radionuclides, using gamma spectrometry, according with EU recommendations. It is found that for cements obtained with addition of thermal power station ash RI varies between 0.16 and 0.38, with an average value by RImed=0.24, namely smaller than maximum value admitted by Romanian’s legislation (RI≤0.5). |
