Uranium and thorium in high purity Nb_2O_5 were determined by neutron activation analysis followed by radiochemical separation(RNAA). A separation procedure combined with anion exchange, solvent extraction with TBP and coprecipitation with LaF_3 was developed and proved to have quantitative yields for the activation products of ^<239>Np and ^<233>Pa. The decontamination factors of major impurities were determined. The detection limit for both elements was less than several ppts when a high flux reactor such as JMTR was available for activation. The method is useful to the other composition materials containing niobium as a matrix element.activation analysishigh purity niobium oxideradiochemical analysis
