“…Among them, radioactive cesium is particularly problematic because of the large quantity released, its relatively long half-life (30.2 yr for Cs-137), and its emission of gamma-rays with high energy. The adsorption and desorption of cesium are strongly dependent on the host materials and the surrounding environment (Kim and Kirkpatrick, 1997;Dumat and Staunton, 1999;Takahashi et al, 1999;Giannakopoulou et al, 2007;Bellenger and Saunton, 2008). Hence, to understand the state and fate of radioactive cesium in the environment at present and in the future, it is essential to determine which types of materials are sorbing radioactive cesium in Fukushima.…”

Radioactive particles of around 50 µm size were collected from highly contaminated soil in the Fukushima Prefecture, Japan, and characterized using micro X-ray diffraction with synchrotron radiation (SR-µ-XRD). Two-dimensional diffraction patterns from individual particles rotated during X-ray irradiation were recorded on a flat imaging plate and a one-dimensional diffraction profile, as a function of 2θ, was derived from the pattern. Weathered biotite (WB) particles with plate-like morphology showed a broad peak corresponding to a basal reflection with d = 10-14 Å, indicating various degrees of vermiculitization. Another peak of~7 Å was also detected in these WB particles, suggesting the parallel growth of kaolinite in the biotite particles. These characteristics were also found in the WB collected from an Abukuma granitic body, which is widespread in the eastern part of Fukushima. SR-µ-XRD of radioactive soil particles consisting of fine minerals or of those rich in organic matter indicated that these particles contain very fine 2:1 type clay minerals alongside detrital rockforming minerals such as quartz and feldspar.

“…The use of a pH buffer was avoided to eliminate possible complexation and competitive sorption. Previous tests have shown the value of K d (Cs) to increase with pH over the range pH 3 to pH 8 (Bayülken et al 2010) but to decrease between pH 8 and pH 10 (Giannakopoulou et al 2007). Values of K d (Ba) on humic acid was seen to increase between pH 2 and pH 4, remain nearly constant between pH 4 and pH 8, and then decrease between pH 8 and pH 10 (Celebi et al 2009).…”

“…They reported that the clay and cesium solution follows the Freundlich type of isotherm. Another group F. Ginannakopulou , C. Haidouit and team have worked on cesium and sandy loam , clay loam, clay systems and concluded that the linear adsorp tion isotherms governs the equi librium relations between the solution and the solid phases [ 12] . Again it is very uncerta in to predic t the adsorption isotherm without experiments.…”

Surface complexation models describing solu tion and surface-phase reactions h ave been used for 30 years. Data for these m odels are derived from experimental techniques with recent advances enabling in vestigation of com plex surfaces. Efforts are directed at un derstanding sorption an d desorption behavior o f contam inates from mineral surfaces, as effected by m icrobial modifications, em ploying isolates obtained from Nevada Test Site deep alluvium as a m odel system. The contam inants will be rad ionuclides with em phasis on actinide elem ents. Characterization of sedim ents will include bulk an alysis by surface are a m easurements, partic le size distribution, X-ray diffracti on, microprobe analysis, chem ical extractions, and molecular and cultivation-based m icrobial comm unity structu re asses sments. Studies on surface interactio n includes: XPS; XAFS; X-ray em ission spectroscopy; TEM analysis ; and SEM charact erization. Non-radioactive isotopes of cont aminants will be used when ne cessary. Collaborators include UNR, UNLV, and DRI. Outcom es will enh ance ba sic sc ientific und erstanding of contam inant behavior on surfaces with significant implications to management of DOE sites.
