DESCRIPTION OF THE INTERACTIONS AND PROCESSES THAT ARE INVOLVED IN TC-99 MOVEMENT AND CYCLING

Objective


The biogeochemical cycle of technetium-99 has been studied and uncertainties associated with predictions have been investigated.

Research activities have been developed along 2 lines. Firstly, the study of bacterial growth as influenced by pertechnetate at different concentrations. Complementary to this approach, the search and identification of bacterial strains with properties of reducing and/or accumulating technetium 99 have been undertaken. Secondly, in order to describe quantitatively the movement of technetium 99 as pertechnetate through soils, the calibration of experimental method to study its sorption to soils has been investigated.
