Analysis of factors affecting the measurement accuracy of high-purity germanium gamma spectrometer

The accuracy of radionuclide detection results is affected by many factors under the condition of using high-purity germanium gamma spectrometer, the selection of spectrometer, calibration of spectrometer, sample preparation, sample measurement, result correction and other aspects were analyzed, and a series of targeted suggestions were put forward. The research shows reasonable detection can improve the accuracy of detection results. (authors)
