Investigation of radionuclides in soil, ash and coal samples collected around yumurtalik sugözü and afşin elbistan power plant

In this study, the radiological characterization of soil, fly ash, bottom ash, slag and coal samples around Afşin-Elbistan thermal power plant and only soil samples near Su gözü thermal power plant were investigated. Natural radionuclide activity concentrations in soil samples which are collected between 0 and 5000 meters from the gates of thermal power plants. All the samples were measured by HPGe gamma spectrometry system. The average activity concentrations of 226Ra, 232Th, 40K in soil samples around Afşin-Elbistan and Su gözü power plants were found to be much higher than limit value of UNSCEAR(United Nations Scientific Committee On The Effects Of Atomic Radiation) report for 226Ra, on the other hand for soil samples of Su gözü power plants does not exceed the limit value. 226Ra, 232Th, 40K activity values were determined for fly ash, bottom ash, slag and coal samples of Afşin-Elbistan power plants. In addition, the values of the radium equivalent activity (Raeq), activity concentration of the index (I ? ), alpha index (I?), gamma dose rate (DR) and the effective dose rate (HR) were calculated.
