英文摘要	aSoil erosion is a global environmental problem, and anthropogenic fallout radionuclides offer a promising tool for describing and quantifying soil redistribution on decadal time scales. The Cs-137 technique for investigating rates and patterns of soil erosion has now been successfully applied in a wide range of environments. This radionuclide strongly adheres to soil particles and therefore can be used as a tracer in soil movement studies. In this work we document the Cs-137 redistribution in an agricultural area, to assess the soil erosion and sedimentation zones. 77 samples were collected from the small Sidi Mohamed Cherif watershed extends over a surface area of 9.45 km(2) located in Oued Isser River in Northwest Algeria. The preparation of soil samples required drying, crushing and sieving to finally <= 2mm diameter. The sample analysis was undertaken by gamma spectrometry, using a high resolution HPGe semi-conductor detector with (1.8 keV for Co-60 1332.5 keV line), after soil characterization with Wavelength Dispersive X-Ray Fluorescence (WDXRF). The spectra were analyzed using the Genie 2000 software dedicated to the processing of gamma spectra. The specific activities of Cs-137 measured ranged from 0.37Bq kg(-1) to 7.8Bq kg(-1). These Cs-137 measurements were used to estimate the spatial distribution of soil erosion in the study watershed.
