“…where ARa is the activity concentration of 226 Ra in Bqkg −1 and if this value exceeds 200 Bqkg -1 in the building material, inhalation of radon from this material may cause the indoor radon concentration to exceed 200 Bqm -3 [10].…”

Natural radionuclides from the uranium ( 238 U) and thorium ( 232 Th) families, as well as the radioactive isotope potassium, are present in varying concentrations in building materials and other construction products obtained from rock and soil. In Italy, in historical monuments, natural building materials have been largely employed for decorative and structural purposes. In this study the natural radioactivity content in six different materials (grey tuff, basalt lava stone, lava stone, sandstone, magmatic rock and travertine) was measured. The activity concentrations were determined by high purity germanium (HPGe) detector-based gamma spectrometry. The radium equivalent activity (Raeq), indoor absorbed gamma dose rate (Din), the annual effective dose (De), and the internal and external hazard indexes were evaluated to assess the radiation hazard according to the international recommendations.

In this study, the activity concentrations of 226 Ra, 232 Th and 40 K in twenty cement samples of four types (CEM, CEM II, CEM III, and CEM IV) collected from building material suppliers in Senegal were measured using a low-background digital gamma-ray spectrometer equipped with broad energy germanium detector. The activity concentrations of 226 Ra, 232 Th and 40 K varied from 7.1-150.3 Bq kg −1 , 3.7-16.1 Bq kg −1 , and 48.7-133.9 Bq kg −1 , respectively. Also, possible radiological risks from the usage of these materials were assessed by estimating external and internal index, indoor absorbed gamma dose rate and the corresponding annual effective dose, effective dose rate to different body organs and tissus, and excess lifetime cancer risk. The estimated radiological hazard indices were revised in light of the relevant national and international legislation and guidance. The values of the radiological hazard indices were found to be within relevant all limit values for structural building materials.
