“…The measurements were conducted with a 50 mL sample, the uranium concentration in the solution was 10 mg L -1 , the activation time was 1 hour, the measurement time varied from 300 to 6000 s with an interval of 300 s. For each of the spectra, LQ was calculated using formula (9). The calculation results are presented in Table 1 and fig.…”

“…Currently, for the determination of uranium, various versions of this method are accepted, including analysis for short-and medium-life radionuclides using thermal and epithermal neutrons [6][7][8]. Analysis on epithermal neutrons using medium-living radionuclides allows one to reach a minimum threshold for the determination of uranium, but requires a reactor as a neutron source [6], while when performing instrumental neutron activation analysis on short-lived isotopes, simpler and more mobile radionuclide neutron sources can be used as a source, for example based on 252 Cf [9]. This work is aimed at developing a method for determining the content of 238 U in solutions using the method of instrumental neutron activation analysis on thermal neutrons, using a radionuclide neutron source based on 252 Cf.…”

“…Reactor sources, or spallation neutron sources, are ruled out for their high construction and operating costs. Isotopic neutron sources cannot provide the necessary high-yield neutron beam, and some suffer from the short half-lives 15 . Therefore, only the accelerator-driven neutron sources can be considered.…”

“…Of these, the two more commonly used, due to their easy ap plicability and efficiency, are the fusion reactions of light nuclei, D D or deuterium tritium (D T). The two main advantages of compact neutron generators over isotopic neutron sources [Vega Carrillo and Martinez Ovalle (2016)] are their high neutron emission intensity, and that neutron generators can be turned off at any time, thus stopping the neutron emission [Chichester (2009)] and reducing the safeguards and radiation protection requirements.…”
