摘要：During the early phase of an accident with the release ofradioactive material to the environment at the local or transboundary scale, arapid and continuous system of information exchange, including real-timemonitoring data to competent authorities and the public, is critical for settingup countermeasures. This information and data exchange must be carried outin a harmonized and consistent manner to facilitate its interpretation andanalysis. After the Chernobyl accident in 1986, and in order to avoidthe competent authorities being unprepared again for a similar event, the EuropeanCommission (EC) defined and put in place a directive (Council Decision87/600/EURATOM, 1987) which essentially obliges a member state that decides toimplement widespread countermeasures to protect its population to notify theEuropean Commission without delay. The same Council Decision also specifiesthat the results of radiological monitoring must be made available to theEuropean Commission and all potentially affected member states. Over the past 30years, the European Commission has invested resources in developing andimproving a complete system to carry out this delicate task, currentlycomposed of two platforms: the European Community Urgent RadiologicalInformation Exchange (ECURIE) and the European Radiological Data Exchange Platform (EURDEP). This paper aims to increase knowledge of the lattersystem as a valuable tool for understanding and analysing the radioactivity levelsin Europe. Commencing with background information, in this paper, we willdescribe the EURDEP system in detail, with an emphasis on its status, dataavailability, and how these data are diffused depending on the audience.Within the scope of this publication, we describe an example of measurementsavailable in the EURDEP system, which to be used for scientific purposes. Weprovide 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, whichoccurred between the end of September and early October 2017. Records storedare publicly accessible through an unrestricted repository calledCOLLECTION belonging to the JRC Data Public Catalogue (https://data.jrc.ec.europa.eu, last access: 1 July 2019).
