N′-tetrabutyl-3-oxa-pentanediamide (TBOPDA) presents excellent extraction abilities for the actinide and lanthanide elements and exhibits a high irradiation stability. In this paper
the effects of irradiation on extraction of TBOPDA have been studied. It is found that TBOPDA has better radiation stability. When irradiation dose reached 1000 kGy and 100 kGy respectively
the distribution ratios of U and Eu declined remarkably. The addition of diluents resulted in a decline of radiation stability.
