Abstract:Air-kerma calibration coefficients were compared at the radiotherapy level for orthovoltage x-ray beams in the SIM.RI(I)-K3 comparison for members of the Sistema Interamericano de Metrología (SIM). Five SIM laboratories participated in the comparison: NIST, NRC, ININ, CNEA and LNMRI, the NIST being the pilot laboratory. Results from the comparison are linked to the BIPM.RI(I)-K3 key comparison reference value through the NIST-BIPM comparison made in 2003 and will meet requirements of the Mutual Recognition Arr… Show more
