Abstract: The measurement principle and analysis method of natural gamma-ray spectra using NalI(T1) scintillation spectrometer are briefly described first, then block diagrams of the HD-8004 Nal(Tl) gamma-ray spectrometer. Finally, sample measurements are listed and discussed. The results are quite promising. Based on the analysis of these measurements, measures to improve the accuracy of spectrum measurement are proposed. It is well hoped that these measures can contribute to the development and application of gamma-ray spectrum measurement.
