Abstract
A beta-spectroscopic method for measurement of the isotope ratios and absolute activities of Sr-90, Y-90 and Sr-89 with an organic scintilla tor is described and tested. The correction factors for absorption in the sample and the detector window are calculated. The method can be u sed for rapid estimation of ratios and absolute activities of pure bet a-emitters after a nuclear accident.
