Description
Metabolites of microbes may form complexes with some radioelements. Dissolved in the porewater these metabolites may therefore decrease sorption and increase solubility of the radioelements concerned. Microbial activity in clay rocks is usually restricted. Microbial activity is not considered any further (second order effect).
