The European Radiological Data Exchange Platform (EURDEP): 25 years of monitoring data exchange

Abstract

Abstract. During the early phase of an accident with the release of radioactive material to the environment at the local or transboundary scale, a rapid and continuous system of information exchange, including real-time monitoring data to competent authorities and the public, is critical for setting up countermeasures. This information and data exchange must be carried out in a harmonized and consistent manner to facilitate its interpretation and analysis. After the Chernobyl accident in 1986, and in order to avoid the competent authorities being unprepared again for a similar event, the European Commission (EC) defined and put in place a directive (Council Decision 87/600/EURATOM, 1987) which essentially obliges a member state that decides to implement widespread countermeasures to protect its population to notify the European Commission without delay. The same Council Decision also specifies that the results of radiological monitoring must be made available to the European Commission and all potentially affected member states. Over the past 30 years, the European Commission has invested resources in developing and improving a complete system to carry out this delicate task, currently composed of two platforms: the European Community Urgent Radiological Information Exchange (ECURIE) and the European Radiological Data Exchange Platform (EURDEP). This paper aims to increase knowledge of the latter system as a valuable tool for understanding and analysing the radioactivity levels in Europe. Commencing with background information, in this paper, we will describe the EURDEP system in detail, with an emphasis on its status, data availability, and how these data are diffused depending on the audience. Within the scope of this publication, we describe an example of measurements available in the EURDEP system, which to be used for scientific purposes. We provide two complete datasets (air-concentration samples – https://doi.org/10.2905/23CBC7C4-4FCC-47D5-A286-F8A4EDC8215F; De Cort et al., 2019a; and gamma dose rates – https://doi.org/10.2905/0F9F3E2D-C8D7-4F46-BBE7-EACF3EED1560; De Cort et al., 2019b) for the recent radiological release of 106Ru in Europe, which occurred between the end of September and early October 2017. Records stored are publicly accessible through an unrestricted repository called COLLECTION belonging to the JRC Data Public Catalogue (https://data.jrc.ec.europa.eu, last access: 1 July 2019).

Advancing Building Assessment Tools: Achieving Sustainable Development Goals through the Fusion of Internet of Things Occupant-Centric Principles and Sustainable Practices

“…According to [20], KPIs are the most efficient way of measuring building performance indicators. For instance, at the building level, the 2010 EPBD recast [46], European Commission [47], and Building Performance Institute Europe (BPIE) [48] supported the move forward to smart buildings (SBs). The EPBD has introduced SRI in buildings to measure the performance of SBs.…”

Emergency Decision Support Techniques for Nuclear Power Plants: Current State, Challenges, and Future Trends

“…Beyond the aforementioned nations, the development of emergency DSSs for NPPs has seen the emergence of key institutions. There are two such entities in accident management and radiological data exchange: CEDIM (https://www.cedim.kit.edu/english/index.php (accessed on 15 May 2024) [235]) and EURDEP (https://remon.jrc.ec.europa.eu/About/ Rad-Data-Exchange (accessed on 15 May 2024) [236]). CEDIM, the Center for Disaster Management and Risk Reduction Technology, prioritizes the advancement of technologies for disaster management and risk mitigation.…”

Analysing the Performance of Radiological Monitoring Network During Nuclear Accidents

“…The arrangement and spatial density of networks dealing with atmospheric nuclear and radiological releases varies from country to country according to the needs and criteria defined by national authorities. An example of this variability is easily seen by visiting the European Radiological Data Exchange Platform (EURDEP), which is the near-real-time exchange system for unvalidated radiological monitoring data from most European countries (Sangiorgi et al, 2020). These networks must be able to detect gradual changes, background patterns and extreme values affecting the population and/or environment during an emergency.…”
