[en] As the solid actinide compounds encountered in radioactive wastes have widely differing aqueous solubilities, methods are required to determine their composition. Analytical methods with the potential to characterise solid actinide compounds in equilibrium with an aqueous phase are reviewed. 'Direct', essentially non-invasive methods were sought. The most promising were identified as photoacoustic and photothermal spectroscopies. A programme is suggested for their study and exploitation. (author)
