摘要

提出了一种计算高分辨率伽玛射线谱峰面积的新方法。该方法将研究光谱区域内连续背景的连续信道计数之间差异的加权平方和最小化，假设背景对能量的线性依赖。在测量信道内容的统计不确定性范围内，新方法得到的结果与“线性加权最小二乘”方法和“感兴趣区域”方法得到的结果一致，前提是峰值位于连续背景上，该背景可以很好地近似于对能量的线性依赖。由于新方法得到的总计数、峰值计数和背景计数之间的相关系数与现有方法不同，因此该方法为伽马射线谱峰分析提供了一种独立的方法。

A new method for the peak analysis of gamma-ray spectra

A new method for calculating the peak areas in high-resolution gamma-ray spectra is presented. This approach minimizes the weighted sum of squares for the differences between consecutive channel counts of the continuous background within the studied spectral region, assuming a linear background dependence on the energy. The results obtained using the new method agree, within the statistical uncertainties of the measured channel content, with those derived from both the “linear weighted Least squares” method and the “Region of interest” method, provided the peaks are on a continuous background, which can be well approximated with a linear dependence on energy. Since the correlation coefficients between the total counts, peak counts, and background counts derived with the new method differ from those obtained using existing methods, the proposed method offers an independent approach to gamma-ray spectral peak analysis.

期刊介绍： Applied Radiation and Isotopes provides a high quality medium for the publication of substantial, original and scientific and technological papers on the development and peaceful application of nuclear, radiation and radionuclide techniques in chemistry, physics, biochemistry, biology, medicine, security, engineering and in the earth, planetary and environmental sciences, all including dosimetry. Nuclear techniques are defined in the broadest sense and both experimental and theoretical papers are welcome. They include the development and use of α- and β-particles, X-rays and γ-rays, neutrons and other nuclear particles and radiations from all sources, including radionuclides, synchrotron sources, cyclotrons and reactors and from the natural environment. The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria. Papers dealing with radiation processing, i.e., where radiation is used to bring about a biological, chemical or physical change in a material, should be directed to our sister journal Radiation Physics and Chemistry.
