Abstract Objective To analyze the national quality control intercomparison of radionuclides γ-energy spectrum analysis in 2014 and verify the reliability of the analysis method of radioactive nuclide. Methods Based on the national standard, we analyzeds the content of radionuclide such as 208Tl、137Cs、228Ac and 40K by using γ spectrometry. Results The deviation between our measured value and the calibration value provided by the organizer is lower than 10%. Both the accuracy and the precision of each radionuclide comparison results meet the requirements; the determination result is "qualified". Conclusion It has proved that the quality guarantee system and quality control technology of our γ-spectrum system are perfected and effective up to now,the measurement method、analysis method and data processing method are reliable.
