DIRAC (DIrectory of RAdiotherapy Centres)


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.


The on-line edition of DIRAC contains data collected since 1995 on radiotherapy resources worldwide. This is updated regularly and features the most current information available to the IAEA, based on replies to the questionnaires circulated. The IAEA makes no warranties, either expressed or implied, concerning the accuracy, completeness, reliability, or suitability of the information. The mention of names of specific companies or equipment does not imply any intention to infringe proprietary rights, nor should it be construed as an endorsement or recommendation on the part of the IAEA. Extracts from the material contained in DIRAC may be freely used provided acknowledgement of the DIRAC database is made.
