| Zusammenfassung | A first key comparison has been made between the air-kerma standards of the PTB and the BIPM in mammography x-ray beams. The results show the standards to be in agreement at the level of the combined standard uncertainty of 3.7 parts in 103. A comparison of the standards has also been made in simulated mammography x-ray beams. The standards agree at the level of the combined standard uncertainty of 3.5 parts in 103. The results are analysed and presented in terms of degrees of equivalence for entry in the BIPM key comparison database. |
