摘要：
Measurement conditions were selected and a procedure was proposed for determining the U-234/U-238 and Th-230/Th-232 isotope ratios using an ELEMENT single-channel double-focusing inductively coupled plasma mass spectrometer. The procedure was tested in analyzing bottom sediments from Lake Baikal with the extraction preconcentration of uranium and thorium. The accuracy of the procedure was verified using certified reference materials and a model solution by comparing the results obtained with the data of alpha spectrometry.
