摘要:
A comparison of the dosimetry for accelerator photon beams was carried out between the Laboratoire National de Metrologie et d'Essais - Laboratoire National Henri Becquerel (LNE-LNHB) and the Bureau International des Poids et Mesures (BIPM) in March 2012. The comparison was based on the determination of absorbed dose to water for three radiation qualities at the LNE-LNHB. The comparison result, reported as a ratio of the LNE-LNHB and the BIPM evaluations, is 0.995 at 6 MV and 12 MV; 0.994 at 20 MV, with a combined standard uncertainty of 5 parts in 10(3) at all three energies. This result is the fourth in the on-going BIPM. RI(I)-K6 series of comparisons.
