Precise 210Pb determination with high-efficiency gamma spectrometry for dating of marine sedimentary cores

[EN]In order to establish the chronology of deep-sea sediments from high-resolution 210Pb-dating, the determination of 210Pb and 226Ra activity concentrations needs to be improved. Gamma spectrometry allows determining simultaneously both radionuclides. However, spectrum background is still an issue...
