- Abstract
In this study, natural (226Ra, 232Th and 40K) and artificial (137Cs) radionuclide activity concentrations were determined seasonally in soil and sediment samples from the extension of the Tunca River in Edirne province of Turkey. Samples were analyzed using a gamma spectrometer system with a high-purity germanium detector (HPGe). The average 226Ra, 232Th, 40K and 137Cs activity concentrations for soil samples were found to be 39.94±0.95 Bq/kg, 55.42±1.02 Bq/kg, 688.21±8.12 Bq/kg and 7.67±0.44 Bq/kg, respectively. The average 226Ra, 232Th, 40K and 137Cs activity concentrations for sediment samples were determined as 40.32±1.39 Bq/kg, 46.90±1.11 Bq/kg, 651.43±7.95 Bq/kg and 7.92±0.41 Bq/kg, respectively. In order to determine the radiological effect; radium equivalent activity, terrestrial absorbed gamma dose rate, annual effective dose equivalent and external hazard index were calculated. The average radium equivalent activity, terrestrial absorbed gamma dose rate, annual effective dose equivalent and external hazard index for soil samples were calculated as 172.19 Bq/kg, 80.86 nGy/h, 99.16 µSv/y and 0.47, respectively. The average radium equivalent activity, terrestrial absorbed gamma dose rate, annual effective dose equivalent and external hazard index for sediment samples were determined as 157.55 Bq/kg, 74.36 nGy/h, 91.19 µSv/y and 0.43, respectively. The obtained values were evaluated in terms of world averages and recommended values.
