摘要: In an inter-laboratory measurement comparison study, four laboratories determined 230Th–234U model ages of uranium certified reference material NBL U050 using isotope dilution mass spectrometry. The dates by the participating range from 9 March 1956 to 19 October 1957, and are indistinguishable given associated uncertainties. These concordant with slightly older than known production age U050.
