This Joint Emergency Management Plan of the International Organizations (Joint Plan) describes the inter-agency framework of preparedness for and response to an actual, potential or perceived nuclear or radiological emergency independent of whether it arises from an accident, natural disaster, negligence, nuclear security event or any other cause.
The following international organizations cosponsor the Joint Plan: the Comprehensive Nuclear-TestBan Treaty Organization (CTBTO), the Euro-Atlantic Disaster Response Coordination Centre (EADRCC), the European Commission (EC), the European Police Office (EUROPOL), the Food and Agriculture Organization of the United Nations (FAO), the International Atomic Energy Agency (IAEA), the International Civil Aviation Organization (ICAO), the International Labour Organization (ILO), INTERPOL, the International Maritime Organization (IMO), the Nuclear Energy Agency of the Organisation for Economic Co-operation and Development (OECD NEA), the Pan American Health Organization (PAHO), the United Nations Development Programme (UNDP), the United Nations Environment Programme (UNEP), the United Nations Office for the Coordination of Humanitarian Affairs (OCHA), the United Nations Office for Outer Space Affairs (OOSA), the World Health Organization (WHO) and the World Meteorological Organization (WMO). In addition, the Joint Plan has been developed in cooperation with the International Federation of Red Cross and Red Crescent Societies (IFRC) and the secretariat of the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR).
The IAEA is the main coordinating body for development and maintenance of the Joint Plan. The Joint Plan is intended to support and underpin the efforts of national governments and seeks to ensure a coordinated and harmonized international response to nuclear or radiological emergencies. It is not intended to interfere with or replace the emergency preparedness and response arrangements of international organizations (or States).
