Radioactivity of some domestic and imported building materials from South Eastern Europe
چکیده انگلیسی

Radioactivity of some building materials, gypsum, ceramic, marble, granite, etc., imported from some neighbour countries of South Eastern Europe (Macedonia, Greece and Bulgaria) or produced in Serbia is presented in this paper. Measurements were done with HpGe detector and multichannel analyser. Activity concentration index, II, defined in [EC 1999, 1999. European Commission. Radiation Protection Unit, Radiological protection principles concerning the natural radioactivity of building materials. Radiat. Prot. 112] was calculated for each investigated sample. The ranges of II are 0.0297–1.2545 and 0.0376–0.1521 for Macedonian and Bulgarian gypsum, respectively. The ranges of II for marble are 0.0124–0.6245, 0.0104–1.2089 and 0.0162–0.6747 for Macedonian, Greek and Bulgarian, respectively. The range of II for Greek ceramic and granite are 0.3508–1.0152 and 0.0438–1.0062, respectively.Concentration of natural radionuclides (226Ra, 232Th and 40K) are in usual range (except few exceptions) and below maximal permitted values, so that examined materials could be used for construction of new buildings (for interior and external works) as well as for covering of pavements, floors, etc.
