摘要：
A new neutron activation technique has been developed for the determination of uranium element concentration and U-235 isotope abundance in nuclear safeguards and reference material samples based on the activation of bare and cadmium-covered samples with different thermal to epithermal neutron flux ratios and on the combination of the two corresponding delayed-fission neutron measurements. The principle of the new technique can be applied also to improve multi-element neutron activation analysis.
