Abstract
A key comparison has been made between the air-kerma standards of the MKEH, Hungary and the BIPM in the low-energy x-ray range. The results show the standards to be in agreement within the expanded uncertainty for the comparison of 4.1 parts in 103. No significant trend with radiation quality is observed. The results are analysed and presented in terms of degrees of equivalence, suitable for entry in the BIPM key comparison database.
