Abstract

Traditional γ-ray spectrum processing software uses full-spectrum stabilization, which can make it difficult to correct peak positions of nuclides after significant nonlinear spectral drift occurs. Additionally, the nuclide activity must be calculated through a complex peak searching process after stabilization. To address these challenges and correct spectral line drift caused by environmental changes in γ-ray spectrum measurements, we propose a Local software Processing method based on Multi-Energy Windows. Our method involves fitting the γ-ray spectrum, dividing it into multiple nuclide energy windows and comparing the fitted peaks within each energy window with standard peaks to correct the spectral lines, which brings each local single peak back to its standard position after stabilization. Simulation experiments show that our method has a stabilization error of less than ±1 channel and provides a significant correction effect for severe nonlinear spectral drift. Furthermore, the corrected fitted peaks can be used directly to calculate the peak area without the need for further peak searching, simplifying the process of nuclide analysis.
