基于幂次方法的快速核素识别应用分析

便携式γ能谱分析仪的数字分析模块是核素定性分析的载体,算法是核心。本文对22Na源测量数据(γ能谱)进行Matlab仿真,在数学处理过程中采取不同平滑次数,然后进行幂次处理,对比分析幂次方法和传统方法的核素识别效果,发现幂次方法的核素识别能力明显优于传统方法。

The digital analysis module of the portable γ ray spectrometer is the carrier of the qualitative analysis, and the algorithm is the core . In this paper, it studies the22Na source Matlab simulation measurement data (γ spectrum). Process with different smoothing times in the process of mathematical treatment and then with power of the method . Compare results by radionuclide identiifcation power of the method and the traditional methods, power of the method is better than traditional methods to improve the radionuclide identiifcation speed.
