Research on possible health implications of EMF exposure is currently active in Europe, with research programmes and activities at both the national and European Commission level. The coordination action EMF-NET, established by the European Commission in 2004, in the framework of the 6th EC Framework Programme, aims to produce the interpretation of the research results on electromagnetic field and health. These will then be used as building blocks by policy and health authorities, starting with the European Commission. This paper will provide an overview of EMF-NET activities.
