An investigation into the role of colloids at a low-level waste repository site

To assess the possible effect of colloids on radionuclide transport in and around the BNFL owned low-level radioactive waste site at Drigg near Sellafield in Cumbria, UK, samples of groundwaters were extracted from the near-field, i.e. from the trenches and from the far-field, i.e. outside the trenches to determine the properties of the groundwaters with respect to the physical characterisation of the waters, colloid population, colloid characterisation and radionuclide loading of colloids.
