The 'CONCERT - European Joint Program for the Integration of Radiation Protection Research' under Horizon 2020 aimed to contribute to the sustainable integration of European and national research programs in radiation protection. CONCERT as a co-fund action strived to achieve the attraction and pooling of national research efforts in radiation protection with EURATOM research programs in this field in order to make better use of public R&D resources and to tackle common European challenges in radiation protection more effectively by joint research efforts in key areas. In order to rise to this challenge CONCERT was operating as an umbrella structure for the research initiatives at the start jointly launched by the European radiation protection research platforms MELODI, ALLIANCE, NERIS and EURADOS and later supplemented by EURAMED and SHARE. Given the limited, indeed even diminishing resources available nationally, in Europe and globally for research on radiation effects in humans and the environment and for radiation protection, and the loss of scientific as well as professional competence in recent years, every opportunity needs to be taken to tailor research activities to the needs of society, authorities and stakeholders, to develop synergies and economies of scale between national competent institutions in this field, particularly to link access to research infrastructures to international research efforts, and to optimize the impact of the EURATOM RTD program by further integrating the radiation protection related education and training activities across Europe. CONCERT strove to stimulate the contribution of Member States to the development of a joint European strategic research agenda (SRA) in the field of radiation protection. This research agenda has to be multidisciplinary in science, tailored to societal needs, make full use of newly gained knowledge in all disciplines of life sciences and humanities and to fully integrate education and training especially for the young generation to build up and maintain competencies needed for a successful, harmonious and sustainable radiation protection regime in Europe today and in the future. Furthermore, CONCERT stimulated the contribution of all national and European actors to it development of a European Joint Research Roadmap (JRM) in the field of radiation protection to lead the way to a sustainable research landscape for radiation protection in Europe. The work of CONCERT was also of importance for society. CONCERT had the mission to address and further reduce uncertainties in the assessment and management of radiation risks humans and to the environment by targeted science. The promotion of joint national and European research and other co-funded integration activities will ensure that human health risks and possible impacts on the environment are better understood and quantified and that radiation protection strategies are optimized. This was achieved by an open exchange of knowledge and information between scientists, regulators, stakeholders involved and society as a whole. Excellence in research is indispensably linked with fair and open competition for research resources. From the beginning, CONCERT was designed around the central idea of ​​organizing open research and development calls as well as calls for activities in education and training. These calls were open to research partners from within and outside the CONCERT consortium. To promote open and fair competition between the research proposals to CONCERT calls, a peer review process with scientists not involved in CONCERT and largely from outside Europe were organized to avoid conflicts of interest influencing the scientific rating of the research proposals.
