| Summary: | The materials characterization based on gamma measurements is one of the main
features for verifying the radioactive materials for safeguards purposes.
This work focuses on the optimization approach in order to find solutions
that include some influence parameters, which should be taken into
consideration during measurements. The considered samples in our work are
certified reference nuclear materials of chemical composition (U3O8) with
different enrichment ratios ranging from 0.31 wt.% to 4.46 wt.%. The gamma
spectrometer based on a planar high-purity germanium detector of
high-resolution was used in the current study. The study of various setups
was experimentally carried out for different cans at different positions for
different energy lines. The verified parameters influencing the
characterization of the measured samples have been estimated. This approach
for the measurement setup of the measured gamma spectra has been successfully
explored to be very affected by different parameters such as the source to
detector position and the various enrichment ratios. Consequently, the
verified and characterized samples could be estimated based on this
optimization approach. |
