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.

The objective of present work is the estimation of Po-210 (polonium) content in the edible
grapevine leaves (Vitis vinifera, L.cv Sultana syn.) collected from Gediz plain in Western
Turkey. Alaşehir District in Gediz plain is one of the most important wineculture region of
Turkey. Grapevine leaves are important food material for Dolma in Turkish cuisine. Dolma is a
name applied to such vegetables as grapevina leaves, cabbage leaves and green peppers stuffed
groundmeat or spiked rice. Levels of Po-210 in the grapevine leaves had not been analyzed
before in Turkey.
In this study, after wet ashing of grapevine leaves, Po-210 was spontaneously plated onto a
copper disc from dilute hydrochloric acid medium and deposited activity was measured. The
results for Po-210 in the grapevine leaves are compared with the other foodstuff values in the
literature.
