An energy spectrum-dose measuring method and device is provided. The method includes: performing energy calibration on a spectrometer using a standard radiation source to obtain a conversion relation between a channel and an energy, where the conversion relation is represented by a calibration factor; measuring ray peaks of n radiation sources with different energies, and dividing energy of an obtained energy spectrum into n regions; performing spectrum collection on the n radiation sources according to the n regions to obtain n net energy spectra subjected to the energy calibration through the calibration factor; performing dose measurement on the n radiation sources sequentially to obtain n dose rates corresponding to the n net energy spectra; calculating a relationship between counting rates of the radiation sources in the n regions and corresponding dose rates; and calculating a full-spectrum dose rate according to a current dose rate of each region.

A nuclide identification method, a system and an electronic device are provided, which relates to the field of nuclide identification. According to statistical characteristics, a background probability density function and a Compton probability density function in a ROI are determined. An energy Bayesian factor and a time Bayesian factor are determined based on energy and time interval information in a sequence of the nuclear detection events obtained by measurement. By combining the two factors, Compton plateau can be effectively identified and distinguished.
