EP-1308 IAEA support to national audit networks for radiotherapy dosimetry.

Abstract

The IAEA has along-standing history providing support and assistance for radiotherapy dosimetry audits in various countries. It has supported the development of methodology and establishment of several national TLD-based QA audit networks for radiotherapy dosimetry. The main objective was to extend the availability of radiotherapy dosimetry audits to as many radiotherapy centres as possible throughout the world. The overall radiotherapy dosimetry audit approach established and developed throughout these CRPs is based on a process of increasingly complex steps and parameters being checked. The first CRP focused on the basic beam calibration audits. The basic programme was extended to audits in non-reference conditions through a second CRP.
