Comparative Determination of Uranium In Silicates by Delayed Neutron Activation Analysis

Abstract

Results of the measurement of uranium in silicate reference materials on the same samples at two different facilities, both using delayed neutron activation analysis, are compared. Good agreement was observed between the results of our two laboratories. Discrepancies have been observed occasionally between different laboratories which utilize delayed neutron activation analysis. On the basis of the results observed in this work, we conclude that discrepant results are not due to variations in the physical facilities of the laboratories.
