Description

The effects of N-, P-, and K- fertilizers on availability of 85Sr, 60Co and 54Mn added to the soil were measured in an open field experiment. The uptake of 85Sr, 60Co and54Mn by tomato and phaseolus was lower in fertilized treatments than in unfertilized ones. The radionuclide availability under fertilized condition depends on soil and element properties. Solubilization of Ca-ions following nitrification of nitrogen in ammonium salts and the presence of stable Strontium, Cobalt and Manganese in the acidifying fertilizers are the main factors giving rise to the reduced radioisotopes uptake by plants. The relative order of uptake of the investigated radionuclides by plants appeared to be as follow 54Mn> 60Co> 85Sr. The distribution pattern of the total absorbed radionuclides in the two plants shows that the shoots contained the highest percent of these radionuclides. Transfer factors for phaseolus plants were higher than those of tomato plants
