Effect of metal complexation on diglycolamide radiolysis: a comparison between gamma and alpha irradiation.

Radiolytic degradation is an important aspect to consider when developing a ligand or a complexant for radionuclides. Diglycolamide extractants (DGAs) have been playing an important role in many partition processes for spent nuclear fuel. In particular, the extractant ,,''-tetraoctyl diglycolamide (TODGA) has been studied intensively for the purpose of solvent extraction processes such as ARTIST, i-Sanex, EURO-GANEX and EURO-EXAM, which have been developed around the TODGA extractant.
