title: Determination of yttrium in rocks by neutron activation and a simple group separation.
abstract: A neutron-activation method is proposed for the determination of yttrium in rocks by separation of the rare-earth group and beta-counting. Interferences from rare-earth nuclides and the necessary corrections are discussed, and results for some standard rocks are presented. The method is suitable for combination with rare-earth determinations by group separation and Ge(Li) gamma-spectrometry.
