In fundamental solvent extraction research at Oak Ridge National Laboratory a large number of systems have been discovered that are selective for one or a few elements. Some of these have been adapted to analytical separation and assay. To serve our own need for highly reproducible and accurate analysis of samples containing ..cap alpha.. and ..beta..-emitting nuclides, we have turned to liquid scintillation in both its familiar ..beta..-liquid scintillation (..beta..-LS) form and in a less-familiar development called Photon-Electron Rejecting Alpha Liquid Scintillation (PERALS) spectrometry. ..beta.. counting by the former and ..cap alpha.. counting by the latter combined with appropriate separation method result in powerful tools for radioassay of a wide range of sample types. 15 refs.
