“…The study of the natural radioactivity levels in building materials is not only needed to assess the possible radiological hazards to human health but also to develop standards and guidelines for the use and management of these materials. 1 In recent years, there has been an increasing interest in the study of the radioactivity in various building materials, 2–25 although there are a few studies on the radioactivity of building materials used. Some cities in Turkey 26–29 require detailed information of the activity concentrations of 226 Ra, 232 Th and 40 K in building materials used but these are not available in literature.…”

In this paper, the natural radioactivity levels in a total of 117 samples of 14 different building materials collected from building construction sites and from the retailers in Adana were studied by means of gamma-ray spectrometer with HPGe detector. The mean activity concentrations of 226 Ra, 232 Th and 40 K measured in the studied building material samples ranged from 2.1 to 88.2 Bq kg À1 , 1.8 to 52.7 Bq kg À1 and 68.1 to 847.5 Bq kg À1 for 226 Ra, 232 Th and 40 K radionuclide, respectively. The external and internal index, the indoor absorbed dose rate and the corresponding annual effective dose were evaluated for potential exposure risks from the usage of the building material samples. The evaluated values of the external and internal index were below the recommended upper level. All the values of effective annual dose determined were lower than recommended exemption level of 0.3 mSv. The results suggest that the use of the studied building material samples in the construction of buildings is unlikely to give rise to any significant radiation exposure to the residents.
