Uptake of¹³⁴Cs by plants from three different types of soil

Abstract

In¹³⁴Cs uptake by the roots of orchard grass and beans planted in three different lands of soil has been studied. For this purpose, a¹³⁴Cs radionuclide solution having 0.3086 μCi/pot radioactivity was added to Ando, Serpentine and Alluial and Clay soil which were fertilized by Standard, −K, +Ca, Water limited and Control for both orchard grass and bean groups. Thus, the above mentioned groups have been harvested and left to dry. The contamination levels these plants have been detected and measured by using an HPGe detector interactively working with MCA. Finally, it has been determined that the¹³⁴Cs uptakes depend primarily on soil characteristics. Besides the decrease in the¹³⁴Cs activity for the plants grown in soils to which the stable cesium or potassium was added 0.011–1.38 per cent activity for the root of plants grown in free K soils was observed. Moreover, highest¹³⁴Cs activity has been determined for the plants grown in −K fertilized soil with respect to the other soil samples.
