Disposal of Smooth γ Spectrum on Matlab Process

College of Naval Architecture and Power, Naval University of Engineering, Wuhan, 430033, China

摘要: 利用NaI(Tl)闪烁探测器得到的γ能谱数据,可能因统计涨落而产生误差。为了降低这一误差提出了γ能谱的平滑方法;根据平滑原理,在Matlab上编程实现谱数据的处理,并对结果进行数学评价;结果表明平滑后的能谱比未平滑的能谱误差要小。

Abstract: Errors may be caused by the statistical fluctuation in the γ spectrum data acquired from NaI（Tl） glitters detector.In order to mitigate this error,the γ spectrum smooth method is proposed in this paper.The process of spectrum data is realized on Matlab according to the smooth principle and the results are as-sessed in mathematics.The results indicate that the errors of the smoothed spectrum are less than those of the non-smoothed spectrum.
