Since 1959, the IAEA has maintained a register of radiotherapy hospitals and clinical institutions having radionuclide and high-energy teletherapy machines. The Directory of Radiotherapy Centres (DIRAC) was first published in book form in 1968. The present electronic version of the Directory is a continuous update, based on replies to questionnaires circulated by the IAEA among its Member States. It includes data not only on teletherapy machines, but also on sources and devices used in brachytherapy, and on equipment for dosimetry, patient dose calculation and quality assurance. Staff strength at the installations (radiation oncologists, medical physicists, technicians, etc.) is included as well.
DIRAC (DIrectory of RAdiotherapy Centres) contains data collected since 1995 on radiotherapy resources worldwide. This on-line edition is updated regularly and features the most current information available to the IAEA. Data are institution based and updated at different time intervals. The source of individual datasets and the date of last update are available by request.
The IAEA makes no warranties, either expressed or implied, concerning the accuracy, completeness, reliability, or suitability of the information.
