AB  - In this study, we report results of the impact of the natural heterogeneity of sandy facies of the Opalinus clay (OPA-SF) on 226Ra uptake in drill core (BAD 1) samples from the Mont Terri underground rock laboratory. The samples were carefully characterized with respect to mineralogy and chemistry using, e.g., XRD and SEM/EDS. The uptake behaviour of 226Ra is evaluated using batch sorption experiments. This dataset contains experimental data on a) 226Ra sorption kinetics and 226Ra sorption on sandy Opalinus Clay as a function of the S/L ratio, b) the characterization of the mineralogical composition of rock samples and the different pore-waters in equilibrium with each clay sample, c) a representation of the mineralogical composition of rock samples in a ternary diagram QFM (quartz, feldspar, and mica), and d) calculated speciation of 226Ra and saturation indices (SI) for Ra-phases in synthetic Opalinus Clay pore water and predicted mole fractions of BaSO4 and SrSO4 in (Sr,Ba)SO4 celestine solid solutions.
