International audience; In 2009, the European Commission published the report of the high-level expert group that had been mandated to consider the scientific challenges posed by the issues of low dose effects of ionising radiation, and to formulate proposals for research policy evolution in this field at European level. This report formulated a first draft of a strategic research agenda. International scientific cooperation and an integrated approach are essential for the further development and enhancement of the international framework of radiation protection. This paper reflects on the results which have been gained through this integration approach strategic research agendas have been established, policies and action plans have been developed for infrastructures and training education, several ambitious research projects have been launched, and a first draft of a European ‘joint road map’ for radiation protection research will be published. Reflecting on the challenges that lie ahead, this paper also presents the initiatives that the five European research platforms (MELODI low dose research; ALLIANCE radioecology; EURADOS dosimetry; NERIS emergency preparedness; EURAMED radiation protection in medical applications) have jointly presented to the European Commission and Euratom member states to further enhance radiation protection research. © 2018, The International Society for Prosthetics and Orthotics.

MELODI is the European platform dedicated to low-dose radiation risk research. From 7 October through 10 October 2013 the Fifth MELODI Workshop took place in Brussels, Belgium. The workshop offered the opportunity to 221 unique participants originating from 22 countries worldwide to update their knowledge and discuss radiation research issues through 118 oral and 44 poster presentations. In addition, the MELODI 2013 workshop was reaching out to the broader radiation protection community, rather than only the low-dose community, with contributions from the fields of radioecology, emergency and recovery preparedness, and dosimetry. In this review, we summarise the major scientific conclusions of the workshop, which are important to keep the MELODI strategic research agenda up-to-date and which will serve to establish a joint radiation protection research roadmap for the future.

- Abstract
Objectives: To assess information reflecting radiation dose and define diagnostic reference levels (DRL) on a European basis for four interventional radiology (IR) procedures considering clinical indication, anatomical region, and procedure., Methods: A prospective European study was performed to provide data on the IR procedures percutaneous recanalization of iliac arteries, percutaneous recanalization of femoropopliteal arteries, transarterial chemoembolization of hepatocellular carcinoma, and percutaneous transhepatic biliary drainage. Hospitals were asked to complete a questionnaire giving information on procedure, equipment, and protocol. Patient size and weight, experience of the operator graded in number of procedures performed, and complexity level of each procedure were reported. Sixteen hospitals from 13 countries could be surveyed. The percentiles of the kerma-area product, fluoroscopy time, cumulative air kerma at the interventional reference point, and number of images were determined. The impact of equipment, year of installation, and complexity level of the procedure on dose were analyzed., Results: DRLs based on clinical indication were defined. Dose values varied considerably within hospitals, between them, and within each subgroup of complexity level. The use of state-of-the-art equipment reduced dose significantly by 52%. Although dose also varied within each subgroup of complexity level, for transarterial chemoembolization of hepatocellular carcinoma and percutaneous transhepatic biliary drainage, dose significantly correlated with complexity., Conclusions: This was the first study reporting exposure practice and defining DRLs based on clinical indication for four IR procedures on a European basis. These DRLs can serve as a baseline for comparison with local practice, the study as a guideline for future surveys., Key Points: • The use of state-of-the-art angiographic equipment reduces dose significantly. • A significant correlation between radiation dose and complexity level is found. • Dose values vary considerably, both within and between individual hospitals, and within each complexity level of interventional radiology procedure., (© 2021.

- Abstract
Objectives: The objective of this study was to investigate the feasibility of defining diagnostic reference levels (DRLs) on a European basis for specific clinical indications (CIs), within the context of the European Clinical DRLs (EUCLID) European Commission project., Methods: A prospective, multicenter, industry-independent European study was performed to provide data on 10 CIs (stroke, chronic sinusitis, cervical spine trauma, pulmonary embolism, coronary calcium scoring, coronary angiography, lung cancer, hepatocellular carcinoma, colic/abdominal pain, and appendicitis) via an online survey that included information on patient clinical, technical, and dosimetric parameters. Data from at least 20 patients per CI were requested from each hospital. To establish DRLs, a methodology in line with the International Commission on Radiological Protection (ICRP) Report 135 good practice recommendations was followed., Results: Data were collected from 19 hospitals in 14 European countries on 4299 adult patients and 10 CIs to determine DRLs. DRLs differ considerably between sites for the same CI. Differences were attributed mainly to technical protocol and variable number of phases/scan lengths. Stroke and hepatocellular carcinoma were the CIs with the highest DRLs. Coronary calcium scoring had the lowest DRL value. Comparison with published literature was limited, as there was scarce information on DRLs based on CI., Conclusions: This is the first study reporting on feasibility of establishing CT DRLs based on CI using European data. Resulting values will serve as a baseline for comparison with local radiological practice, national authorities when DRLs are set/updated, or as a guideline for local DRL establishment., Key Points: • First study reporting on the feasibility of establishing CT diagnostic reference levels based on clinical indication using data collected across Europe. • Only one-fourth of the hospitals had CT machines less than 5 years old. • Large dose variations were observed among hospitals and CT protocols were quite different between hospitals.

- Abstract
Background: In August 2017, the European Commission awarded the "European Study on Clinical Diagnostic Reference levels for X-ray Medical Imaging" project to the European Society of Radiology, to provide up-to-date Diagnostic Reference Levels based on clinical indications. The aim of this work was to conduct an extensive literature review by analysing the most recent studies published and the data provided by the National Competent Authorities, to understand the current situation regarding Diagnostic Reference Levels based on clinical indications for computed tomography., Results: The literature review has identified 23 papers with Diagnostic Reference Levels based on clinical indications for computed tomography from 15 countries; 12 of them from Europe. A total of 28 clinical indications for 6 anatomical areas (head, cervical spine/neck, chest, abdomen, abdomen-pelvis, chest-abdomen-pelvis) have been identified., Conclusions: In all the six anatomical areas for which Diagnostic Reference Levels based on clinical indications were found, a huge variation of computed tomography dose descriptor values was identified, providing evidence for a need to develop strategies to standardise and optimise computed tomography protocols.

- Abstract
The paper presents, from a European point of view, the combined scientific and sociological rationale for further development of research into the biological effects and risks related to population exposures to low dose/low dose rate ionizing radiation. It further explains how this rationale led to the constitution, at European level, of the MELODI Association, to foster innovative and multidisciplinary research programs dedicated to this objective, and driven by a consensus-based Strategic Research Agenda (SRA). Finally, the paper suggests that this evolution towards a more integrated and multi-disciplinary approach to research in the field of low dose/dose rate radiation exposure effects and related risks could lead to new research opportunities also at an international level.

- Abstract
Purpose: This paper provides an update and summary on the organization of European research in the field of low dose risk and radiation protection. To address declining resources and competence in radiation protection and related research across European countries, a High Level and Expert Group (HLEG) was established in 2007. The HLEG identified key policy and scientific questions to be addressed through a strategic research agenda for low dose radiation risk. This initiated the establishment of a European Research Platform, called MELODI (Multidisciplinary European Low Dose Research Initiative). Dr Bill Morgan closely followed the European low dose programme and chaired the international Advisory Boards of DoReMi Network of Excellence and the MELODI platform., Conclusion: The MELODI research platform is dedicated to low dose ionizing radiation risk. In 2010, MELODI was founded as a registered association with 15 members. As of September 2016, the association´s membership increased to 46. A major activity of MELODI is the establishment and updating of a long-term Strategic Research Agenda (SRA) for research on low dose risk in Europe. The SRA is intended to guide the priorities for national and European research programmes and the preparation of competitive calls at the European level. A key priority for radiation protection research is to improve health risk estimates for exposures corresponding to the dose limits for occupational exposures and to reference levels for the exposure of the population in emergency situations.

- Abstract
The importance of low-dose risk research for radiation protection is now widely recognised. The European Commission (EC) and five European Union (EU) Member States involved in the Euratom Programme set up in 2008 a 'High Level and Expert Group on European Low Dose Risk Research' (HLEG) aimed at identifying research needs and proposing a better integration of European efforts in the field. The HLEG revised the research challenges and proposed a European research strategy based on a 'Multidisciplinary European LOw Dose Initiative' (MELODI). In April 2009, five national organisations, with the support of the EC, created the initial core of MELODI (http://www.melodi-online.eu) with a view to integrate the EU institutions with significant programmes in the field, while being open to other scientific organisations and stakeholders, and to develop an agreed strategic research agenda (SRA) and roadmap. Since then, open workshops have been organised yearly, exploring ideas for SRA implementation. As of October 2014, 31 institutions have been included as members of MELODI. HLEG recommendations and MELODI SRA have become important reference points in the radiation protection part of the Euratom Research Programme. MELODI has established close interactions through Memorandum of Understanding with other European platforms involved in radiation protection (Alliance, NERIS and EURADOS) and, together with EURADOS, with the relevant medical European Associations. The role of Joint Programming in priority setting, foreseen in the forthcoming EU Horizon 2020, calls for keeping MELODI an open, inclusive and transparent initiative, able to avoid redundancies and possible conflicts of interest, while promoting common initiatives in radiation protection research. An important issue is the establishment of a proper methodology for managing these initiatives, and this includes the set-up of an independent MELODI Scientific Committee recently extended to Alliance, NERIS and EURADOS, with the aim of identifying research priorities to suggest for the forthcoming Euratom research calls., (© The Author 2015.
