Particle size determinations of six sand and alluvium samples from Dounreay, Caithness, Scotland

This report describes particle size analysis of six soil samples from Dounreay, Caithness,
Scotland, provided by Clive Auton in October 2006. It is part of the work under a United
Kingdom Atomic Energy Authority (UKAEA) contract to characterise the Quaternary deposits
from the Dounreay site and also includes bulk mineralogy, clay mineralogy, particle size
distribution, cation exchange capacity (CEC), total organic carbon (TOC) and total inorganic
carbon (TIC) data presented elsewhere. These materials were collected using a window sampler
during June and July 2006 at the Dounreay site. This data was required by UKAEA to provide
background mineralogical, geochemical and physical properties information to enable the
evaluation and modelling of the transport radionuclide contamination in the geosphere. This
report presents the results of the BGS analyses. The report consists of factual data only.
