Abstract: Remote beam output audit results from the Australian Clinical Dosimetry Services (ACDS), the International Atomic Energy Agency (IAEA), the Imaging and Radiation Oncology Core (IROC), and Radiation Dosimetry Services (RDS) were compiled and evaluated from 2010 to the present. The failure rate (i.e., beam output was outside the +/-5% tolerance) was evaluated for photon and electron beams as a function of the year of irradiation as well as the nominal beam energy. Finally, examples of confirmed calibration errors were compiled to provide guidance to clinical physicists as well as auditing bodies.
