Özet

Indoor radon survey and gamma activity measurements in soil samples were carried out in the Giresun province (Northeastern Turkey). The result of analysis of variance showed a relationship between indoor radon and radium content in soil (R-2=0.54). It was found that indoor radon activity concentration ranged from 52 to 360 Bq m(-3) with an average value of 130 Bq m(-3). A model built by BEIR VI was used to predict the number of lung cancer deaths due to indoor radon exposure. It Was found that indoor radon is responsible for 8% of all lung cancer deaths occurring in this province. (CS)-C-137 activity concentration was measured 21 years after the Chernobyl accident. The results showed that Cs-137 activity concentration ranged from 41 to 1304 Bq kg(-1) with an average value of 307 Bq kg(-1). The indoor radon results and the geology of the studied area were discussed. Annual effective doses to the both radionuclides of natural origin and (CS)-C-137 were estimated. (C) 2008 Elsevier Ltd.
