The radioactivity concentrations of 40 K, 232 Th and 238 U in 20 specimens of commercial flooring materials used in Karbala governorate, were measured using (HPGe) system. The results of measurements have shown that highest value of specific activity of for 238 U which was 294.570Bq/kg (granite; Vietnamese origin), 232 Th which was 88.808Bq/kg (granite; Italian origin) and 40 K which was 284.580Bq/kg (marbles; Iranian origin), which were less than the worldwide average (UNSCEAR,2000). The various hazard indices were also calculated to assess the radiation hazard. It was found that none of the results exceed the recommended limit value. All specimens in this paper are within the recommended safety limit and do not present huge radiation dangers.
