Fast radiochemical separations for neutron-deficient short-lived nuclides

Simple and exotic radiochemical techniques used for the separation purification and analysis of neutron-deficient short-lived nuclides are reviewed. These range from classical wet-chemical methods to automated and instrumental techniques. Special attention is given to chemical adjuncts of the He-jet recoil-transport technique and to high-resolution mass spectrometry. Recent developments in biological applications, including 13N production and use are overviewed. (author) 38 refs.; 10 figs
