About EURDEP

Legal basis

Legal basis

EURDEP (EUropean Radiological Data Exchange Platform) is a network for the exchange of radiological monitoring data between 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 38 European 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 submission statistics can be found HERE.

Data aggregation

Data Aggregation

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, if necessary converted from EURDEP 2.1 to IRIX 1.0 or backwards, and aggregated into the common database before being given back to the data providers.

The participating organizations can subscribe to various data queues to automatically receive the aggregated dataset with newest European monitoring data.

Authorized users can do more such as access all European monitoring data through various web-services and other secure channels.

Data visualization

Data visualization

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

The Simple 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, e.g. air concentration measures. The general public and scientists are a target auditorium.

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

Data formats

Data Formats

Triggered by its Member States the European Commission (EC) created the EUropean Radiological Data Exchange Platform (EURDEP)  in 1994. The resulting EURDEP 2.1 data format is used by European countries to exchange their radiological monitoring data in almost real-time.

The IAEA has recently released the International Radiological Information Exchange (IRIX) as the recommended standard to exchange information among emergency response organizations at national and international levels during a nuclear or radiological emergency. Version 1.0 of the IRIX format was issued on 31 March 2013.

Since 2013 EURDEP is fully compliant with both data formats, EURDEP 2.1 and IRIX 1.0

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.

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. 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.
