Show affiliationsA key comparison has been made between the air-kerma standards of the NIM and the BIPM in the medium-energy x-ray range. The results show the standards to be in general agreement at the level of twice the stated relative standard uncertainty of 3.1 × 10-3, although there is evidence of a trend in the results at different radiation qualities. The results are analysed and presented in terms of degrees of equivalence, suitable for entry in the BIPM key comparison database.
