  • Determination of Caesium and its Isotopic Composition in Nuclear Samples Using Isotope Dilution-Ion Chromatography-inductively coupled Plasma Mass Spectrometry


As the natural isotopes of Ba give isobaric interference's on the radioactive isotopes of Cs at nominal masses of 134, 135 and 137, a chemical separation of Cs from Ba has been necessary for the determination of the isotopic composition of Cs by mass spectrometric techniques in highly active nuclear wastes, dissolved spent nuclear fuels or radioactively contaminated environmental samples.
