The concentrations of 226Ra, 232Th, and 40K are measured in the material collected from two locations. The collected materials are analyzed using gamma-ray spectrometry. The activity concentration of the naturally occurring radionuclides 226Ra, 232Th, and 40K in building material varies from 12.6 to 121.4, 13.6 to 142, and 69.5 to 620.6 Bq kg−1, respectively. The radium equivalent activity, absorbed dose rate, annual effective dose, and hazard index are also calculated.
