“…The migration of the Cs-137 radionuclide through soil was observed in the Goiâ nia accident (IAEA, 1988), and also surrounding the Hanford plant (Flury et al, 2004) where high levels of Cs-137 caused by seepage were detected in sediments and in other studies (McKinley et al, 2001;Bostick et al, 2002;Flury et al, 2002;McKinley et al, 2004;Todorović et al, 1992;Chowdhury et al, 2004). Several studies have assessed the factors that cause adsorption of Cs-137, and the type and location of Cs + ion adsorption in the inner layers and the frayed edge sites (FES) of phyllosilicate minerals, such as vermiculite, illite, kaolinite, muscovite, and others (Figueira & Cunha, 1998;Flury et al, 2004;McKinley et al, 2001;Nyarko et al, 2011;Dion et al, 2005;Bostick et al, 2002;Flury et al, 2002;Lujanienė et al, 2005;McKinley et al, 2004;Todorović et al, 1992;Chowdhury et al, 2004;Komarneni, 1985;Kanai et al, 2013;Rajec et al, 1999;Sawhney, 1970;EPA, 1999;Wahlberg & Fishman, 1962). McKinley et al (2004) reported that the absorption of Cs + ions by phyllosilicate minerals, such as illite and kaolinite, is favorable.…”
