“…The first 10cm of topsoil was taken as most of the 137 Cs is stored in these layers (Schimmack et al, 1989;Owens et al, 1996;Schoorl et al, 2004); foreign bodies were removed and the remaining soil samples were set for laboratory preparation. The samples were dried at room temperature to a constant weight.…”

“…Artificial radionuclides can also be present such as 137 Cs is resulting from fallout from weapons testing and some other human activities involving the use of these radionuclides (Walling & Quine, 1991;Wu & Tiessen, 2002;Schoorl et al, 2004;Heckrath et al, 2005). The radiological implication of these radionuclides is due to the gamma-ray exposure of the body and irradiation of lung tissue from inhalation of radon and its progenies.…”

Natural radioactive materials under certain conditions can reach hazardous radiological levels. Therefore, it becomes necessary to study the natural radioactivity levels in soil to assess the dose to the population in order to determine the health risks and to obtain a baseline for future changes that may occur due to human activities.The motivation for this study was the devastating civil war that took place in Nigeria from 1967 to 1970, in which the study area was one of the battle fields. Th and 40 K ranged from 15.42±1.10 to 40.99±1.36 nGy/h. The radium equivalent activity (R eq ) and the annual effective dose rates were also calculated and found to vary from 33.39±2.44 to 85.07±2.96 Bq/kg and from 18.91±1.35 to 50.27±1.69 µSv/y respectively. These values were found to be within the same range as recommended values . The study also indicated that 137 Cs detected at three locations is an indication of the presence of artificial radionuclides which can be linked to the war that took place in the ancient town of Ore.

“…137 Cs was analyzed in soil samples of a depth of 10 cm as most of the 137 Cs is stored in this section (Schimack et al, 1989, Owens et al, 1996, Schoorl et al, 2004). Five to nine samples were taken at each hillslope section during summer seasons 2006 and 2007.…”

Abstract. Soil erosion has been discussed intensively but controversial both as a significant source or a significant sink of atmospheric carbon possibly explaining the gap in the global carbon budget. One of the major points of discussion has been whether or not carbon is degraded and mineralized to CO 2 during detachment, transport and deposition of soil material. By combining the caesium-137 ( 137 Cs) approach (quantification of erosion rates) with stable carbon isotope signatures (process indicator of mixing versus degradation of carbon pools) we were able to show that degradation of car-
