Summary:

This publication by the International Atomic Energy Agency provides an international code of practice for dosimetry in external beam radiotherapy. It focuses on standards of absorbed dose to water, crucial for accurate radiation therapy treatments. The document outlines methodologies for calibrating ionization chambers and determining absorbed doses for various radiation beams, including photon, electron, proton, and heavier ion beams. It aims to ensure consistency and accuracy in dosimetry across global healthcare facilities, reducing uncertainties in treatment delivery. The work is endorsed by professional societies and targets professionals in radiotherapy and dosimetry. Generated by AI.
