Abstract

In this study, a practical method for the determination of 63Ni in radwaste samples was established. The results showed that the condition of duplicate elution with the Ni-resin column and the presence of the carrier Mn can effectively remove unwanted interfering radionuclides with decontamination factors of >104 for 60Co. The highest activity of 63Ni in radwaste samples was determined to be 2.86 ± 0.04 Bq/g, whereas the minimum detectable amount was approximately 0.04 Bq/g. The established separation technique can be used for the practical determination of 63Ni in radwastes and for the classification of radwastes.
