[en] In this study, activities of radioactive polonium and natural radionuclide concentrations in fertilizer most consumed in agricultural lands in Turkey were measured. Fertilizers containing phosphorus and potassium increase yield and quality. But, they contain some radionuclides. These radionuclides dissolve in water and first transport into plants and then transport from plants to humans. In the latest years, artificial fertilizing has replaced natural fertilizing in agriculture. Therefore, fruits and vegetables contain radionuclides those are found in artificial fertilizers. In this study, electrochemical deposition technique with alpha counting method was used for determining the radioactivity level of polonium in fertilizers. Radium, potassium and thorium concentrations were measured by gamma spectrometry. TSP, MAP, DSP,MKP, (15-15-15), (18-18-18), (20-20-20) compost fertilizers consumed at most has been analyzed and the results were evaluated with respect to human health
