- Abstract
α-Radiation effect on the solvent extraction of Am using the solution of N,N,N′,N′-tetraoctyldiglycolamide was investigated by means of the external and internal irradiation systems. In contrast to the internal irradiation system using an actinide radionuclide as an α-particles emitter, the external irradiation with He ions provided by an accelerator can be carried out in a reasonable timescale and without contamination with radionuclides. No significant decrease in distribution ratio was observed even after irradiation over 200 kGy in both systems. It was also confirmed that the external irradiation system could be a useful alternative to the internal irradiation.
