Soil sampling was carried out during the period of May to June 2006 at different points around Es-Salam reactor facility. Four undisturbed soils, typical and representative of the studied region, have been chosen. All samples were originating from the surface layer with a depth ranging from o to 40 cm and collected at increasing distances(0.8, 10 and 20 km from the Es-Salam reactor facility. Selected points were appointed: "Site"Birine", "Hade" and"Khachem". Respectively, the first was named"Site", as it is close to the reactor site(800 m). The second point is near to the Birine city about 10 krm from the reactor to the east. The third is located 20 km southwards Finally, the last one is situated 20 km northwest. Soil samples were divided into two parts intended respectively for physi- cochemical analysis and for Cs Sr contamination. The part destined to the physicochemical analysis was air-dried, sieved through a 2 mm mesh and homogenized with manual stirring before analyses.
