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 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 map shows measurements of environmental radioactivity in the form of gamma dose rate averages and maxima for the last 24 hours. These measurements originate from some 5000+ stations.

The map utilizes a responsive web technology that allows it to be displayed on variety of phone and tablet browsers.

The Advanced map shows measurements of environmental radioactivity in the form of hourly gamma dose rate averages going back up to 35 days. The measurements originate from approximately 5000 stations.

The map displays essential information to explain various environmental radioactivity phenomena, and offers more options for data filtering and analysis. Due to the large amount of displayed data, this map is not suitable for phone browsers.

Web Widget

A widget is a stand-alone application that can be embedded into third party sites by any user on a page where they have rights of authorship, e.g. a webpage, blog etc.

For instance, the widget could be hosted in a page of a website belonging to a national data provider or a national authority, see this example.

Although the widget looks like it is running on the hosting website, it actually loads all the markup, code and data from our services. The maintenance of the widget remained on our side while you simply display the data.


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