Radionuclide Migration Studies in the Laboratory

Abstract

Laboratory radionuclide migration studies form an essential link between static sorption studies and field migration studies, and provide valuable information for the validation of radionuclide transport models. Results are presented for a number of small-(< 10 cm) and medium-scale (10 to 30 cm) migration experiments in fractured granite, using 137cs, 75Se, 237Np, and 241Am, as well as results for migration experiments using conservative, inactive tracers in large-scale laboratory experiments (30 to 100 cm).
