Separation of Americium in High Oxidation States from Curium Utilizing Sodium Bismuthate

Electrochemical Separation of Curium and Americium

The objective of this project is to develop a method for the separation of Am from Cm based on electrochemical techniques. Electrochemical systems that allow the thermodynamics of actinide and lanthanide complexes to be systematically evaluated and tuned will be examined. The influence of complex formation on the ability to selectively isolate a given species electrochemically will be evaluated...

Separation of Americium and Curium by Chromatographic Technique Using Tertiary Pyridine Type Resin

The group separation of trivalent actinides and lanthanides and the mutual separation of americium and curium are necessary for the transmutation of americium. We have proposed the separation system based on the chromatography using the tertiary pyridine-type resin. In this separation system, the complete separation method of the trivalent actinides and lanthanides are already established using...

Transfer of plutonium, americium and curium from fallout into reindeer after the Chernobyl accident

Several reindeer tissue samples were analysed for transuranium elements following the Chernobyl accident in 1986. Pu, Am and Cm were separated using coprecipitation and anion exchange steps, and measured with alpha spectrometry. The activity concentrations of Pu in reindeer liver found in this study (0.0094–0.062 Bq kg d.w. [= dry weight]) are low compared to the concentrations found in the 196...
