DESCRIPTION:An ICTP-IAEA meeting \n	Dosimetry is fundamental for radiother
 apy including brachytherapy. It has been recognised that harmonising dosim
 etry internationally is essential. The IAEA\, working with various profess
 ional societies\, has been key in writing international codes of practice 
 for dosimetry.\n	In 2023 the IAEA published TRS-492\, dosimetry in brachyt
 herapy\, which addresses SSDLs and hospitals. This is the first code of pr
 actice for brachytherapy as the IAEA had previously published an IAEA-TECD
 OC-1274 Guidelines on standardized procedures at Secondary Standards Dosim
 etry Laboratories (SSDLs) and hospitals. The TRS-398 Rev.1\, Absorbed Dose
  Determination in External Beam Radiotherapy was published in 2024. This i
 s a revision of the previous publication from the year 2000. This publicat
 ion addresses the need for a systematic and internationally unified approa
 ch to the calibration of ionization chambers in terms of absorbed dose to 
 water and to the use of these detectors in the determination of absorbed d
 ose to water for the radiation beams used in radiotherapy — namely low\,
  medium\, and high energy photon beams\, electron beams\, proton beams and
  heavier ion beams. It is addressed to users provided with calibrations in
  terms of absorbed dose to water traceable to a standards dosimetry labora
 tory. The SSDL’s also implement the formalism and code of practice discu
 ssed in this publication.Topics\n\n		The international measurement system
