In this paper, standardization of the activity concentration of gaseous beta-emitting radionuclide 85Kr is introduced. The measurement was performed at the recent-established primary standard at the National Institute of Metrology of China (NIM), which consists of a set of internal gas proportional counters of different length. Samples suitable for High Purity Germanium gamma-ray spectrometry measurement were also prepared, and efficiency calibration at an energy of Eγ = 514 keV with standardized 85Kr source in a given geometrical container is presented.
