“…Although manure was shown to provide high amounts of potassium leading to an illitization of the clay fraction as in case of the KCl-plot (Pernes-Debuyser et al, 2003), the incorporation of organic matter increases the amount of negative charges, obviously favoring perennial sorption of 137 Cs. This result is however divergent with respect to many other studies which highlight the role of organic matter to favor Cs mobility (Staunton and Levacic, 1999;Chibowski and Zygmunt, 2002;Nakamaru et al, 2007). In case of the NH 4 NO 3 plot, according to work of Giannakopoulou et al (2007) the low pH (4.5) would be unfavorable to Cs sorption, in contradiction with the low k-factors observed in Fig.…”

“…have also been proposed (Faroussi et al, 2007). The convection model is basically rendered using a serial compartmental scheme, where the soil is split into a set of N horizontal and connected layers (Kirchner, 1998;Chibowski and Zygmunt, 2002). Each compartment is considered as a box characterized by its own downward transport rate, k i .…”

“…If historical 137 Cs deposition is not available, a single pulse into the surface soil horizon is sometimes considered. This simplification is reasonable in contaminated areas such as Central or Eastern Europe, where Chernobyl-derived fallout predominates over global nuclear bomb-derived inputs (Chibowski and Zygmunt, 2002;Hrachowitz et al, 2005). When studies integrate the complex history of 137 Cs fallout, continuous deposition is approximated by a series of single depositions (Hö lgye and Maly, 2000).…”

An 80-year soil archive, the 42-plot experimental design at the INRA in Versailles (France), is used here to study long-term contamination by 137Cs atmospheric deposition and the fate of this radioisotope when associated with various agricultural practices: fallow land, KCl, NH4(NO3), superphosphate fertilizers, horse manure and lime amendments. The pertinence of a simple box model, where radiocaesium is supposed to move downward by convectional mechanisms, is checked using samples from control plots which had been neither amended, nor cultivated since 1928. This simple model presents the advantage of depending on only two parameters: alpha, a proportional factor allowing the historical atmospheric 137Cs fluxes to be reconstructed locally, and k, an annual loss coefficient from the plow horizon. Another pseudo-unknown is however necessary to run the model: the shape of historical 137Cs deposition, but this function can be easily computed by merging several curves previously established by other surveys. A loss of approximately 1.5% per year from the plow horizon, combined with appropriate fluxes, provides good concordance between simulated and measured values. In the 0-25cm horizon, the residence half time is found to be approximately 18yr (including both migration and radioactive decay). Migration rate constants are also calculated for some plots receiving continuous long-term agricultural treatments. Comparison with the control plots reveals significant influence of amendments on 137Cs mobility in these soils developed from a unique genoform.

“…These results support the validity of the results of in situ experiments conducted by Nakanishi et al (2014). However, peat soil with high organic matter content exhibited a migration rate of more than 1.0 cm year À1 (Rosèn et al 1999;Chibowski and Zygmunt 2002). The soil type is related to the downward migration of 137 Cs in surface soil.…”

The Chernobyl nuclear power plant accident in 1986, the Mayak reprocessing plant accident in 1957, and the Fukushima nuclear power plant accident in 2011 have released various radionuclides. Spatial distribution of radionuclides in surface soil constitutes fundamental information related to radiation exposure and to post-accident sources for secondary dispersion of radionuclides. The spatial and vertical distributions of 137 Cs, 90 Sr, and Pu from those three nuclear accidents were reviewed to elucidate the fate of the radionuclides in the soil environment. This chapter specifically presents information about the dynamics of radiocesium ( 134 Cs and 137 Cs) in the soil of contaminated areas because of its long half-life and its major contribution to the overall external radiation dose. Along with an examination of global fallout, for soils of various types, the existence forms and geochemical behavior of radiocesium in surface soil after the Fukushima accident are reviewed, as are similar results from the Chernobyl and Mayak nuclear accidents.

“…The 137 Cs migration in soil is a complicated process and depends on many factors, e.g. the soil type and texture, its pH, physicochemical interactions with soil and sorption mechanism (Arapis et al, 1997;Chibowski and Zygmunt, 2002;NCRP, 2006). Its vertical migration in soils has a direct effect on the level of external radiation exposure to people living in contaminated areas.…”

In order to study the vertical migration of anthropogenic 137 Cs, soil inventories of this radionuclide were measured in two regions selected on the basis of a previous comprehensive survey in the northern Iranian province of Guilan located in the South Caspian region. Ten sampling stations were randomly chosen in these regions and split-level sampling was carried out to a depth of 30 cm. Sample analysis was performed using a HPGe detector system. In situ gamma measurements in both regions were also carried out with the aid of a portable germanium spectrometer. The experimental data were then compared with the solution of the convectiondispersion equation (
