The influence of clay mineralogy on the mobility of radiocaesium in upland soils of NW Italy

Export of <sup>134</sup> Cs and <sup>137</sup> Cs in the Fukushima river systems at heavy rains by Typhoon Roke in September 2011

“…All samples include clay minerals such as chlorite, vermiculite, smectite, mica, and kaolin. Clay mineral types in the fixation of radiocesium have been widely claimed (e.g., Facchinelli et al, 2001;Korobova et al, 2007). For example, an increase in 137 Cs-specific activity was observed in floodplain soil with increased smectite content in clay fractions (Korobova et al, 2007).…”

Removal of Radioactive Cesium (134Cs plus 137Cs) from Low-Level Contaminated Water by Charcoal and Broiler Litter Biochar

“…Radioactive cesium fallout on soil is commonly contained within the upper 5 cm of the soil layer associated with clay, and only a small portion of radioactive cesium is considered mobile (Facchinelli et al, 2001;Matsunaga et al, 2013;Sanderson et al, 2001). However, radioactive cesium may slowly be redistributed due to uptake of mobile cesium by plants and by repartitioning in the ecosystem through equilibration with non-radioactive cesium (Sanderson et al, 2001;Yoshida et al, 2004).…”

Properties of 137Cs in marine sediments off Yangnam, Korea

“…He and Walling (1996) found that the concentration of 137 Cs adsorbed to different size fractions is closely related to the specific surface areas of the fractions. The relationship between 137 Cs concentration and particle size or organic matter content has been extensively studied in an effort to better understand the distribution properties and behavior of 137 Cs in soil (Fawaris and Johanson, 1995;Hird et al, 1995;He and Walling, 1997;Lee et al, 1997;Takenaka et al, 1998;Lee and Lee, 2000;Facchinelli et al, 2001;Rigol et al, 2002).…”
