Adsorption of uranyl onto ferric oxyhydroxides: Application of the surface complexation site-binding model
TLDR
In this paper, the surface complexation-site binding model of Davis et al. was used to predict uranyl adsorption from aqueous electrolyte solution onto well-characterized goethite, amorphous ferric oxyhydroxide and hematite sols at 25°C.About:

Radiological characterization of tap waters in Croatia and the age dependent dose assessment.
TL;DR: Contribution of each particular radionuclide to total doses varied among different age groups but for each group the lowest contribution was found for (226)Ra and the highest for (228)Ra, which makes them the most critical group of population.

EBS Radionuclide Transport Abstraction
TL;DR: In this article, the authors developed and analyzed the EBS RT abstraction model, consistent with Level I and Level II model validation, as identified in ''Technical Work Plan for: Near-Field Environment and Transport: Engineered Barrier System: Radionuclide Transport Abstraction Model Integration'' (BSC 2005 [DIRS 173617]).

Uranium and strontium isotopic evidence for strong submarine groundwater discharge in an estuary of a mountainous island: A case study in the Gaoping River Estuary, Southwestern Taiwan
Ruo-Mei Wang,Chen-Feng You +1 more
TL;DR: In this paper, over 50 river water samples were collected in three sampling schemes from the Gaoping River Estuary (GRE), the largest river catchment in southwestern Taiwan and were analyzed for major/trace elements, uranium (U) and strontium (Sr) isotopic compositions using multi-collector inductively coupled plasma mass spectrometry (MC-ICP-MS).

TL;DR: Combined effects of P (P-/P+ used to modulate plant physiology) and citrate (model exudate) on the solubilization of U contained in the soils were tested in closed reactors (batch) and suggested a complex combination of mechanisms and factors including desorption, resorption), precipitation, precipitation, co-sorption.

Predicting the bioavailability of sediment‐bound uranium to the freshwater midge (Chironomus dilutus) using physicochemical properties
TL;DR: In this paper, the Windermere Humic Aqueous Model (WHAM7) was used to predict sediment-associated U bioavailability using simple regressions and a geochemical speciation model.

Uranium solution-mineral equilibria at low temperatures with applications to sedimentary ore deposits
TL;DR: The Gibbs free energies, enthalpies and entropies of 42 dissolved uranium species and 30 uranium-bearing solid phases have been critically evaluated from the literature and estimated when necessary for 25°C.

Surface ionization and complexation at the oxide/water interface
TL;DR: In this article, a method for determination of intrinsic ionization and complexation constants of oxide surface sites from potentiometric titration data is reported using these experimental properties and the stoichiometry of surface reactions, surface charge, σo, adsorption density, Γi, and diffuse layer potentials, ψd, at the oxide/water interface.

Surface ionization and complexation at the oxide/water interface II. Surface properties of amorphous iron oxyhydroxide and adsorption of metal ions
James A. Davis,James O. Leckie +1 more
TL;DR: In this paper, the site-binding model for the electrical double layer of hydrous oxides reported in a previous paper is applied to the adsorption of metal ions from dilute solution and to complex heterogeneous systems, i.e., amorphous iron oxyhydroxide.
