abstract = {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.},
