Video Tutorials to Determine the Absorbed dose to Water for High Energy Photon Beams

Interactive tutorials are made available to help users apply the recommendations contained in TRS 398, to determine the absorbed dose to water for high energy photon beams.

The tutorials are intended to be used by clinically qualified medical physicists (CQMPs) and presupposes underlying knowledge in the field of radiotherapy. IAEA relevant publications include: IAEA TRS No. 398, also available in Spanish and Russian, IAEA TRS No. 469, Radiation Oncology Physics: A Handbook for Teachers and Students and relevant slides.
