abstract = {In this study we performed microscopic characterization of
mineral particles that were collected in the thorium-rich
Fen Complex in Norway and identified and isolated based on
autoradiography in function of their radioactivity. For this
we combined information obtained with X-ray absorption
$μ$-CT, $μ$-XRF and $μ$-XRD, both in bi- and in
three-dimensional (tomographic) mode. We demonstrate that
radionuclides and metals are heterogeneously distributed
both within soil samples and within individual Th-enriched
aggregates, which are characterised as low-density mineral
bulk particles with high density material inclusions, where
Th as well as several metals are highly concentrated. For
these sites, it is important to take into account how these
inhomogeneous distributions could affect the overall
environmental behaviour of Th and progeny upon weathering
due to human or environmental factors. Moreover, the
estimated size of the Th-containing inclusions as determined
in this work represents information of importance for the
characterization of radionuclides and toxic metals exposure,
as well as for assessing the viability of mining for Th and
rare-earth metals in the Fen Complex and the associated
environmental impact.},
