The activity concentrations of 238U, 232Th and 40K in brick, cement and sand samples used as building materials in Manisa province were analysed by a gamma-ray spectroscopy coupled with a NaI (Tl) detector. Doses received by the citizens living in Manisa due to these building materials were also calculated. The highest activity concentrations of 238U, 232Th and 40K found in the sand samples were 1559.10Bq·kg -1 , 142.48Bq·kg -1 and 1711.47Bq·kg -1 , respectively. The maximum mean of radium equivalent activity Ra eq was 945Bq·kg -1 calculated for levels in sand, gravel and stone samples.
