| Research Abstract |
In the actual partitioning process of spent nuclear fuel, an organic extractant will be exposed to α-particles emitted from minor actinides, as well as β- and γ-rays. In this study, α-radiolysis of tetraoctyldiglycolamide (TODGA) was investigated by the irradiation with helium ions provided by accelerators. It was found that the radiation chemical yield for the degradation of TODGA by helium ions was less than that by γ-rays.
