Concentrations of natural radionuclides (226Ra, 232Th and 40K) content and its radiological hazards were presented in this paper for variety of commonly used building materials soil, sand, redbrick, clay brick, limestone and cement. Measurements were done by using gamma spectrometry (NaI (Tl) 3”x 3”). The radiation hazard indices like: Radium equivalent (Raeq), external hazard index (Hex), activity concentration index (Iex), the specific dose rates in door (D), and the annual effective dose (DE) due to gamma radiation were calculated and compared with internationally recommended values.
