IAEA audits

IAEA has a long history of radiotherapy audits. Various types and levels exist: • Comprehensive or clinical audit – QUATRO (review of the whole radiotherapy practice: structure, process and outcome) • Partial audit, e.g. dosimetry or TPS only • One-off or routine audits on regular basis, e.g. TLD audits of beam calibration • Investigation in response to suspected or reported incident/accident (reactive audit)
