Description

Geochemical reactions due to changed redox conditions (atmospheric oxygen, redox front migration, etc.), pH plume (cement dissolution) etc. can lead to changes in porewater composition and in mineral composition (dissolution, secondary minerals) and can therefore change sorption and solubility properties for the radioelements.
