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

A key comparison has been made between the air-kerma standards of the KRISS, Republic of Korea, and the BIPM in the low-energy x-ray range. The results show the standards to be in agreement at the level of the standard uncertainty of the comparison of 2.2 parts in 10 3 . The results are analysed and presented in terms of degrees of equivalence, suitable for entry into the BIPM key comparison database. To reach the main text of this paper, click on Final Report .
