IEC 61452-2021 核儀器--放射性核素r射線(xiàn)發(fā)射率的測量--鍺分光儀的校驗和應用 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.
