UPTAKE OF CS-134 BY PLANTS FROM 3 DIFFERENT TYPES OF SOIL

In Cs-134 uptake by the roots of orchard grass and beans planted in th ree different lands of soil has been studied. For this purpose, a Cs-1 34 radionuclide solution having 0.3086 muCi/pot radioactivity was adde d to Ando, Serpentine and Alluial and Clay soil which were fertilized by Standard, - K, + Ca, Water limited and Control for both orchard gra ss and bean groups. Thus, the above mentioned groups have been harvest ed and left to dry. The contamination levels these plants have been de tected and measured by using an HPGe detector interactively working wi th MCA. Finally, it has been determined that the Cs-134 uptakes depend primarily on soil characteristics. Besides the decrease in the Cs-134 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 plant s grown in free K soils was observed. Moreover, highest Cs-134 activit y has been determined for the plants grown in - K fertilized soil with respect to the other soil samples.
