The European Radiological Data Exchange Platform (EURDEP) is a network for the exchange of radiological monitoring data between most European countries. The participation of the EU member states is regulated by the Council Decision 87/600 and the Recommendation 2000/473/ Euratom. The participation of non-EU countries is on a voluntary basis. There is however a gentlemen's agreement that participating to EURDEP automatically means that data delivery will continue during emergency.

EURDEP is developed and maintained by the Joint Research Centre of the European Commission.

Data Exchange

Data exchange

The EURDEP network is currently used by participating countries for the continuous exchange of data from their national radiological monitoring networks in almost real-time. Continuously (routine and emergency) each organization makes data available on an hourly basis. 

Data Exchange

Data is collected from the national data servers through dedicated channels. Collected national datasets get distributed among several mirrored file servers to ensure a higher data availability especially during a radiological accident.

All incoming data-files are checked and aggregated into the common database before being given back to the data providers. The participating organizations can subscribe to various notification queues to automatically receive the aggregated dataset with latest monitoring data.

Public maps and services

Public maps and services

Freely accessible public maps allow viewing the monitoring data in a simple, intuitive way.

The Simple real-time monitoring map shows the latest measurements of environmental radioactivity in the form of gamma dose rate averages and maxima for the last 24 hours. It utilizes a modern responsive web design, which allows this map to be viewed on variety of desktop, tablet and smartphone browsers.

For more detailed information we operate the Advanced map, where users can find more specific, detailed information needed to explain various phenomena of environmental radioactivity. The general public and scientists are a target auditorium.

In addition we provide a number of free services which can be used by the website visitors. Detailed information about how to use maps and services can be found in the section Services of this website.

Some countries however impose a delay (between 0-999 hours) before the data becomes available to the public.

International collaboration

International collaboration

EURDEP is also a standard format for radiological data submission and exchage between monitoring systems. The latest release of the format is version 2, which is in use since the beginning of 2002. The data-format is applied for participation to the EURDEP network, but also for other national and international systems such as CBSS, MODEM, ARGOS, RODOS etc.

Since 2013 the platform is compliant with the requirements of the International Radiological Information Exchange (IRIX) format, developed by IAEA. The European Commission takes an active part in the development of the IRIX format and its propagation to exchange radiological monitoring data at regional and world-wide scales.

In 2014 EURDEP started the submission of the European radiological data to the International Radiation Monitoring Information System (IRMIS) under provisions given by the Conventions on Early Notification and Assistance in the case of a nuclear accident or radiological emergency (ENAC). In this way EURDEP assures the role of European Regional HUB for IRMIS.
