The most important international partners of the NEOC are:
- Neighbouring countries (Germany, France, Austria and Italy)
- International Atomic Energy Agency (IAEA) in Vienna
- European Union (EU)
- Nuclear Energy Agency (NEA)
- European Space Agency (ESA)
- Partnership for Peace (PfP)
On the basis of bilateral agreements, the NEOC is part of an international warning and information system via the emergency operations centres of its neighbouring countries and the International Atomic Energy Agency (IAEA) in Vienna.
The NEOC is the national contact point and competent authority for the notification agreement concerning nuclear accidents (EMERCON alarms). Parallel to this, the European Union has established an alarm system ECURIE (European Community Urgent Radiological Information Exchange), for which the NEOC has also assumed the role of national contact point and competent authority. In accordance with the UNECE convention, the NEOC is also the national contact point for chemical accidents with cross-border consequences.
The Nuclear Energy Agency, which is a subdivision of the OECD, is concerned with radiation protection issues at governmental level. It produces a series of publications and carries out international exercises, in which the NEOC also participates.
In addition, the NEOC is also in regular contact with the emergency operations centres of other countries. These contacts are growing in importance as a result of the greater speed with which information can be exchanged worldwide.
The large international organisations involved in radiation protection are primarily responsible for the exchange of information at a scientific level. One of the most important of these is the International Radiation Protection Association (IRPA), which has around 16,000 members from 42 countries and 37 national or regional organisations. The Association of German and Swiss Radiation Protection Specialists (FS) is the IRPA member organisation for these two countries.
