IEC has recently published a new edition of IEC 61452:2021, Nuclear instrumentation – Measurement of activity or emission rate of gamma-ray emitting radionuclides – Calibration and use of germanium-based spectrometers, (https://iss.rs/sr_Cyrl/project/show/iec:proj:102452).
This standard defines the methods for calibrating and using germanium-based spectrometers that measure photon energies and emission rates as well as calculate radionuclide activities based on these measurements. With this standard, it is possible to have a basis for the routine calibration and use of germanium semiconductor detectors. It provides a unified approach to evaluate their performance characteristics, which ultimately improves the quality and accuracy of the instrumentation systems.
