Key comparison BIPM.RI(I)-K2 of the air-kerma standards of the BFKH, Hungary, and the BIPM in low-energy x-rays

Abstract

Main textA key comparison has been made between the air-kerma standards of the BFKH, Hungary, and the BIPM in the low-energy x-ray range. The results show the standards to agree at the level of the expanded uncertainty of the comparison of 6.8 parts in 103. The results are analysed and presented in terms of degrees of equivalence, suitable for entry in the BIPM key comparison database.To reach the main text of this paper, click on Final Report.
