Determination of the isotope ratio234U/238U with a scintillation α-spectrometer

A method has been developed for the determination of the isotope ratio²³⁴U/²³⁸U. The preparation of the radiation source and a procedure based on the scintillation measurement of the α-spectrum are described. The results obtained are compared with data of the α-β method used earlier. By way of example, a few isotope ratios obtained in the examination of natural waters are presented for comparison. The results show the advantages of the application of the simple scintillation α-spectrometer and the justification of its use for²³⁴U/²³⁸U serial measurements.
