Low concentrations and complex sample matrices have made the determination of actinide concentration in the environment a time consuming and complicated task. This paper presents three methods for actinide analyses in environmental samples using extraction chromatography: (i) for the separation of thorium (Th), U, Fu and Am in bone ash, (ii) for the separation of Fu and Am from MOX material and (iii) for the separation of Th from soil. These methods are fast and simple and give reliable results with high recoveries and pure spectra.
