DOIAbstract
Building materials of different brands were assessed for the concentrations of 226Ra, 232Th and 40K using HPGe detector. The activity concentrations in the measured samples ranged from 27 ± 8 to 82 ± 8 Bq kg−1 for 226Ra, 41 ± 4 to 101 ± 8 Bq kg−1 for 232Th and 140 ± 8 to 940 ± 19 Bq kg−1 for 40K, respectively. The Radium equivalent (Raeq) activity from the samples was found to be <370 Bq kg−1 as the recommended value for construction materials. This study will set a baseline data for significant standards on radiation exposure of the measured radionuclides in the selected building materials used in Nigeri
