2026-05-18 Raw Gamma-Ray Spectra Dataset of Five Radionuclides doi:10.57760/sciencedb.j00186.01032 en This dataset contains the original gamma energy spectrum data of five radioactive nuclides: 241Am, 133Ba, 60Co, 137Cs, and 152Eu. The data were obtained through measurement using a portable NaI(Tl) detector and are saved as the raw energy channel count spectra directly collected by the detector, without undergoing energy calibration conversion, interpolation, normalization, or any other preprocessing. The experiment set different source-detector distances ranging from 5 to 10 cm, and repeated sample collection under different measurement times, while also collecting the environmental background energy spectrum. This dataset can be used for gamma energy spectrum preprocessing, nuclide identification, low-count energy spectrum analysis, and training of deep learning models, among other research purposes.
