The most likely process that can lead to the release of radionuclides from radioactive waste repository in a geological media is transport by groundwaters. Research in this field has led to the experimental determination of distribution coefficients. The influence of distribution coefficients was studied in detail for uranium and radium adsorption on clay. Therefore, with batch tests, the influence of sorption and desorption coefficients in rock/groundwater systems of the Ciudanovita site was investigated. Results for corresponding studies with radium and uranium in clay-groundwater systems are given, which point to the possibility of transferring laboratory batch data to field conditions by mathematical model. The present work is based mainly on this research direction: optimization and improvement of the performances obtained from the geo-chemical processes investigation methods in the waste dumps and the surrounding geological structures to isolate them in order to reduce the negative environmental impact. Measurements of the two radionuclides concentrations in particles with different dimensions were made to supply accurate information regarding the selection of remediation strategies for the dumpsite in study.
