摘要

Building materials of different brands were assessed for the concentrations of Ra-226, Th-232 and K-40 using HPGe detector. The activity concentrations in the measured samples ranged from 27 +/- 8 to 82 +/- 8 Bq kg(-1) for Ra-226, 41 +/- 4 to 101 +/- 8 Bq kg(-1) for Th-232 and 140 +/- 8 to 940 +/- 19 Bq kg(-1) for K-40, 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 Nigeria
