IEC 61452-2021 核仪器--放射性核素r射线发射率的测量--锗分光仪的校验和应用 Nuclear instrumentation – Measurement of activity or emission rate of gamma- ray emitting radionuclides – Calibration and use of germanium-based spectrometers

This document establishes methods for the calibration and use of high purity germanium spectrometers for the measurement of photon energies and emission rates over the energy range from 45 keV to approximately 3 000 keV and the calculation of radionuclide activities from these measurements. Minimum requirements for automated peak finding are stated. This document establishes methods for measuring the full-energy peak efficiency with calibrated sources.
