Validating dose rate calibration of radiotherapy photon beams through IAEA/WHO postal audit dosimetry service.
In external beam radiation therapy (EBRT), the quality assurance (QA) of the radiation beam is crucial to the accurate delivery of the prescribed dose to the patient. One of the dosimetric parameters that require monitoring is the beam output, specified as the dose rate on the central axis under reference conditions. The aim of this project was to validate dose rate calibration of megavoltage p...
متن کاملAppendix to Iaea Calibration Certificate Well Type Chamber and Electrometer Calibration Procedure at the Iaea Dosimetry Laboratory
At SSDLs the recommended detector for the calibration of all brachytherapy photon sources, as well as for the calibration of intravascular beta sources, is an appropriately calibrated well type chamber. For SSDLs the preferred method for traceability in the source calibrations is to have the well type chamber calibrated against the primary standard at the PSDL. However, due to practical reasons...
متن کاملQA networks for radiotherapy dosimetry
Several national and international organizations have developed various types and levels of external audits for radiotherapy dosimetry, either based on on-site review visits or using mailed dosimetry systems. Three major TLD (thermoluminescent dosimetry) networks make available postal dose audits to a large number of radiotherapy centres on a regular basis. These are the IAEA/WHO TLD postal dos...
متن کاملSkin in vivo Dosimetry in Radiotherapy
Introduction: Due to the prevalence of skin problems in patients after radiotherapy, skin dose measuring is importance. Content: Skin in vivo dosimetry means measuring the patient's (or phantom) skin dose during radiotherapy. According to the ICRP 59, the dose at the depth of 0.07 mm is known as a skin dose. The most radiosensitive epidermis cells are located...
متن کاملThe IAEA/WHO TLD postal programme for radiotherapy hospitals.
BACKGROUND AND PURPOSE Since 1969 the International Atomic Energy Agency (IAEA), together with the World Health Organization (WHO), has performed postal TLD audits to verify the calibration of radiotherapy beams in developing countries. MATERIALS AND METHODS A number of changes have recently been implemented to improve the efficiency of the IAEA/WHO TLD programme. The IAEA has increased the n...
