Abstract
A key comparison has been made between the air-kerma standards of the NIST and the BIPM in the low-energy x ray range. The results show the standards to be in general agreement at the level of the combined standard uncertainty for the comparison of 4.1 parts in 103, although the results for the different radiation qualities show variations that are larger than would be expected. The results are analysed and presented in terms of degrees of equivalence, suitable for entry in the BIPM key comparison database.Citation
