The International Atomic Energy Agency (IAEA) is an international organisation working to promote the safe, secure and peaceful use of nuclear technologies. The IAEA's medical programme is led by its Nuclear Medicine and Diagnostic Imaging (NMDI) section while the Radiation Protection of Patients (RPOP) unit is dedicated to helping professionals achieve safer use of ionising radiation for patients. In addition to providing information to professionals and the public, each year a number of IAEA conferences and technical meetings bring together experts from all over the world to discuss issues relevant to radiology.
The Bonn Call for Action, issued by the IAEA and the WHO in 2012, sets out the international agenda for radiation protection, and forms the basis of the ESR EuroSafe Imaging Call for Action. The ESR is working closely with the RPOP unit in this context.
In February 2017, the ESR and the IAEA concluded a practical arrangement on capacity building, education and training in the area of diagnostic imaging including hybrid imaging, building on the longstanding cooperation between the ESR and the NMDI section.
The World Health Organization is the United Nations organisation dedicated to promoting health around the world. The ESR works with the WHO in areas like radiation protection, patient safety and education. The WHO has a dedicated programme for ionising radiation including medical radiation exposure.
The International Society of Radiology, of which the ESR is a member, is an accredited non-governmental organisation with the WHO and regularly participates in meetings at the WHO headquarters in Geneva, Switzerland.
The International Commission on Radiological Protection (IRCP), an independent international organisation established in 1928, has developed, maintained, and elaborated the International System of Radiological Protection used world-wide as the common basis for radiological protection standards, legislation, guidelines, programmes, and practice.
The ESR works closely with ICRP on all issues related to medical radiation protection, focusing on the principles of justification, optimisation, and dose limitation. ICRP is represented on the ESR Radiation Protection Subcommittee.
The Heads of the European Radiological Protection Competent Authorities (HERCA) is a voluntary association of Europe's national radiation protection authorities established in 2007. HERCA has a Working Group on Medical Applications (WG MA) dedicated to issues such as justification of medical exposures, cooperation with CT manufacturers, or the implementation of the EURATOM Basic Safety Standards Directive.
The ESR cooperates with HERCA on the issue of justification through its multi-stakeholder meetings, developing and implementing self-commitments to improve justification processes in radiology, and regularly contributing to discussion or position papers.
