FEP Effects

Description of FEP Effects

Depending on their size, colloids may be transported at different rates than fully dissolved species. Colloids may retard radionuclide transport by sorption of dissolved radionuclides onto colloids and subsequent filtration or sorption of the colloids by the EBS or natural materials; colloids may also enhance radionuclide transport by sorption of dissolved radionuclides and colloid transport with flowing groundwater through fractured media in channels where velocities are greatest.
