The superimposition interferences of fission nuclides and spectral interferences from uranium in neutron activation analysis of La
Lu
Sm
Ce
Nd
Mo
Zr
Ba
Br etc. in geological samples have been studied systematically. The uranium fission coefficiints
by
thermal and epithermal neutron activation and spectral peaks of
239
Np and
147
Nd have been determined experimentally. The control of key experimental conditions is described with a discussion about correcting uranium interference in the determination of REE for different geological samples.
