New life sciences findings from Institute of Radiochemistry published

Current study results from the report, 'X-ray absorption and photoelectron spectroscopy investigation of selenite reduction by FeII-bearing minerals,' have been published. "The long-lived radionuclide 79Se is one of the elements of concern for the safe storage of high-level nuclear waste, since clay minerals in engineered barriers and natural aquifer sediments strongly adsorb cationic species, but to lesser extent anions like selenate (SeVIO4(2-)) and selenite (SeIVO3(2-)). Previous investigations have demonstrated, however, that SeIV and SeVI are reduced by surface-associated FeII, thereby forming insoluble Se0 and Fe selenides," scientists in Dresden, Germany report.
