Modelling multiple dispersion of radionuclides through the environment

Particulate Phases Possibly Conveyed from Nuclear Waste Repositories by Groundwater

“…Since they are living organisms they migrate in the subsurface porous medium, being subject to a complex of biological, physical and chemical processes. Those micro-organisms act as pseudo-colloids, since their surfaces are often negatively charged, thus having the ability to bind and carry radionuclides through the subsurface environment (Johnsson et al, 2008;Luk'yanova et al, 2008;Seiler et al, 2011;Singer, Farges & Brown Jr, 2009;Wilkins et al, 2006;2010).…”

“…The role played by the colloidal phase is intensely investigated not only for groundwater, but also for terrestrial surface water, namely for streams and lakes (Aleksandrova et al, 2010;Bondareva, 2011;Matsunaga et al, 2004;Monte, 2010;Monte et al, 2009;Ollivier et al, 2011;Semizhon et al, 2010), for estuarine water (Barros et al, 2004;Eyrolle & Charmasson, 2004;Porcelli et al, 1997), for sea water (Bowie et al, 2010;Otosaka et al, 2006;Scholten et al, 2005) or for soil water Maity et al, 2011;Matisoff et al, 2011;Rachkova et al, 2010;Seliman et al, 2010;Xu et al, 2011). The colloid-radionuclide interaction is important not only from the perspective of their migration.…”

“…Radionuclide migration with groundwater colloids through porous media (e.g., Bradford & Bettahar, 2006;Delos et al, 2008;Ilina et al, 2008;Kretzschmar et al, 1997;Li et al, 2010;Panfilov et al, 2008;Santos & Barros, 2010), or across fractured rock systems (e.g., Hu & Mori, 2008;Jeong et al, 2011;Kosakowski, 2004;Kurosawa & Ueta, 2001;Malkovsky & Pek, 2009b;Schindler et al, 2010;Tang & Weisbrod, 2009;2010;Yamaguchi et al, 2008) are intensely investigated topics. At the same time, extensive research is conducted for assessing the humic and fulvic colloids effect on the radionuclides migration across the underground environment (e.g., Geraedts & Maes, 2008;Joseph et al, 2011;Pshinko, 2009;Pshinko et al, 2009;Schmeide & Bernhard, 2010;Singh et al, 2009;Singhal et al, 2009;Yoshida & Suzuki, 2006).…”
