| Zusammenfassung | An intercomparison of the absorbed dose rate in tissue, Dt(0.07), at radiation protection levels for beta dosimetry was performed between two national metrology institutes, the D I Mendeleyev Institute for Metrology (VNIIM) in St. Petersburg (russia) and the Physikalisch-Technische Bundesanstalt (PTB) in Braunschweig (Germany), from 2009 to 2010. For this comparison, radiation sources of both institutes were calibrated using the primary standard measuring devices (extrapolation chambers) of both institutes, i.e. no transfer instrument was used as both primary standards were directly compared. The values of the absorbed dose rates in tissue agree within 1.2 % for two different 90Sr/90Y sources, within 1.0 % for one 85Kr source and within 1.5 % and 4.2 % for two different 147Pm sources. All these deviations are within 1 to 2 times the corresponding standard deviations. |
