| Résumé : | In view of the potential geochronological value of the natural radioactivity of Lu-176, three quantitative methods have been developed for the measurement of lutetium in minerals: neutron activation based on radiochemical separation and beta-counting of Lu-176 m; non-destructive neutron activation analysis by gamma counting Lu-177 on a Ge-Li detector; stable isotope dilution and mass spectrometry. The three methods give concordant results for a gadolinite sample. © 1969. |
