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

A key comparison has been made between the air-kerma standards of the NPL, UK and the BIPM in the low-energy x-ray range. The results indicate a progressive drift of the NPL standard, now lower than the BIPM standard by around 1 part in 102. The expanded uncertainty (k = 2) of the comparison is 4.2... Full description

520 |a A key comparison has been made between the air-kerma standards of the NPL, UK and the BIPM in the low-energy x-ray range. The results indicate a progressive drift of the NPL standard, now lower than the BIPM standard by around 1 part in 102. The expanded uncertainty (k = 2) of the comparison is 4.2 parts in 103. The results are analysed and presented in terms of degrees of equivalence, suitable for entry in the BIPM key comparison database. [Copyright IOP Institute of Physics Publishing.
