摘要
能谱分析是一种重要的核技术分析方法,是解决地球科学、环境科学等有关问题的重要手段。本文讨论了基于LabVIEW能谱分析系统的设计方法,借鉴小波分析的思想和高斯拟合,较好地实现了α、γ能谱曲线的平滑与寻峰,及能量刻度、辐射总量与氡气浓度计算,铀、钍、钾含量的计算与分析。采用基于LabVIEW的虚拟仪器技术,结合计算机硬件资源,提高了系统运算处理能力,节约了开发成本,同时具有人机交互界面友好直观,操作方便的特点,可被广泛应用于矿产分析,建材或环境的辐射评价等场合。
Energy spectral analysis is an important method for applications in earth science, environmental science, and other fields of research. In this paper, we introduce a new spectral analysis system based on LabVIEW. By wavelet analysis and Gaussian fitting, functions are realized to smooth, identify and scale the peaks of an α- or γ-ray spectrum. Concentrations of the radon gas, and the uranium, thorium and potassium radionuclides, are calculated. By the virtual instrument technology based on LabVIEW, one is able to make full use of computer hardware resource and improve the processing capacity of the system with reduced costs. The system, with a user-friendly interface, can be widely used in applications of mineral analysis, building material analysis, environmental assessment of the radiation, and many other occasions.
