Abstract:
In our work we have investigated the radioactive metals 226Ra (238U) series, 232Th series, 40K and 137Cs radionuclides) and the heavy metals (Zn, Fe, Mn, Ni, Cu, Pb and Cd.) were determined in the collected samples. In The 1st part of the thesis includes results of the radiation hazard indices for shore sediment samples have the values of 50.74±2.04, 29.07±1.09, 0.14±0.01 and 186.51±6.91 for radium equivalent activity (Raeq) in (Bq/Kg), absorbed dose rate in nSv/h in air (D), external hazard index (Hex) athe mean concentrations of Zn, Fe, Mn, Ni, Cu, Pb and Cd ions are 137.8,862.44, 70.75, 23.51, 24.5, 25.54 and 11.15 μg/kg dry weight, respectively. For the shore sediment samples, it was found that the mean concentrations of Zn, Fe,
