Abstract
The first step in a spectrum analysis is the determination of peak areas, which form the basis for all subsequent steps of the analysis aimed at activity determination. To maintain reliability of the final results the analysis checks the peak areas results for consistency. This is done by repeating the peak analysis with three different peak search programs, by comparing their results and by calculating the best estimate. When a disagreement is found, the uncertainty of the peak analysis result is increased to accommodate the disagreement.
