Abstrakt: This paper presents an update of the recommended half-lives published in X- and gamma-ray standards for detector calibration (IAEA, 1991 and 2007) performed as part of the Coordinated Research Project under the auspices of the IAEA. The half-lives of 61 radionuclides were updated during the years 2018-2020 using a well-established methodology to select the dataset. The recommended half-lives were obtained using weighted or unweighted sample means and the consistency of the results was investigated and discussed based on the chi-square test.
