A process combining liquid–liquid extraction with ion exchange for strontium traces removal in the presence of an excess of sodium concentrations is described. In this continuous process, strontium is extracted from acidic (0.9 M) solution using a

The radiolytic products of the DCH18C6 obtained after γ-irradiation have been determined, and the seven main structures have been separated and analyzed. The radiolytic product yields range from about 0.01 to nearly 0.3 molecules per 100 eV absorbed
