Based on the concept of relative detection efficiency

some experiments have been conducted to measure the isotopic abundance and the age of the plutonium material in a sealed container by a high-resolution γ-ray spectrometer. The PC/FRAM software analyzes the spectra. The study shows that the analysis precision of the isotopic abundance and the age will rise as the spectral measurement precision increases

and that if the spectral measurement precision is not high enough

the analyzed results by the PC/FRAM software might be unsatisfactory. Hence

the study suggests that a spectral peak should be monitored to shed light on the spectral measurement precision during the spectrum acquisition process.
