| The activity concentration of 226Ra, 232Th and 40K in seven cement types from different factories and grinding plants were measured using a gamma ray spectrometry with HPGe detector. The average activity concentrations observed in the studied cement samples (all from 141 samples) were 40.0 ± 27.1, 28.0 ± 20.9 and 248.3 ± 95.0 Bq kg-1 for 226Ra, 232Th and 40K, respectively. The radium equivalent activity (Raeq), the representative level index, the indoor absorbed dose rate and the corresponding annual effective dose were estimated for the potential radiological hazard of the cement. The Raeq values were compared with the corresponding values for cement of different countries. The mean indoor absorbed dose rate (87.4 ± 48.5 nGy h-1) is slightly higher than the population-weighted average of 84 nGy h-1, whereas the corresponding effective dose rate (0.4 ± 0.2 mSv y-1) is lower than the dose criterion of 1 mSv y-1. The obtained results indicate no significant radiological hazards arise from using Turkish cement in building construction. © The Author 2007. Published by Oxford University Press.
