Vertical distribution of the natural and artificial radionuclides in various soil profiles to investigate soil erosion

Vertical distributions of Cs-137 and Ph-210 in soil profiles were examined to study their availability in soil erosion at Gokova region where there exists intensive agricultural activities on sloppy fields. Since the mobility of these radionuclides depend on soil characteristics, soil samples were analyzed also for their physical and chemical properties. From Cs-137 inventories measured, erosion rates for cultivated and disturbed (no cultivation) soils were calculated to range from 79.1 to 6.5 t.ha(-1).y(-1) and from 79.9 to 3.5 t.ha(-1).y(-1), respectively. the Pb-210 technique is found to be not suitable for erosion determination for this area, presumably due to the coal-fired power plants operating in the region.
