Abstract

The concentrations of 226 Ra, 232 Th, and 40 K 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 226 Ra, 232 Th, and 40 K 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.
