Abstract: | Summary The possible correlation between the self-attenuation correction in gamma-spectrometric assay of uranyl nitrate samples and
spectral line intensity ratios was investigated experimentally and simulated numerically using MCNP code. The characteristic
gamma- and X-lines of uranium were measured using a low energy Ge gamma-spectrometer. The simulation results agreed with the
experimental data and showed obvious correlation between the self-attenuation correction and the intensity ratios (185.7
keV)/(143.8 keV), (98.44 keV)/(185.7 keV) and (185.7 keV)/(63.23 keV)]. This correlation greatly simplifies the determination
of the self-attenuation correction and reduces the troublesome traditional procedures used to determine this coefficient. |
