Enrichment analysis of uranium in uranium oxide by gamma-ray spectrometry without using calibration standards

摘要

An analytical method for the determination of uranium enrichment in uranium oxide without using any calibration standards is described. Very good agreement between the measured and certified values was obtained in the analysis of a Standard Reference Material. Precise energies and emission probabilities were derived for two weak gamma-rays of Pa-234m: at 258.227 +/- 0.003 keV, (0.076 +/- 0.002)% and 742.813 +/- 0.005 keV, (0.106 +/- 0.002)%.
