The introduction of novel technologies such as 5G and 6G communication systems or the installation of new high tension lines cause concerns about possible health effects by the public, governments, and authorities. Therefore, in this project, electromagnetic field (EMF) exposure assessment in real environments will be investigated. Spatial and temporal monitoring of telecommunications (5G) and of extreme low frequency (ELF) exposure of high tension lines will be realized. EMF monitoring nodes will be designed and will be installed in real environments. For future 6G technologies, hybrid numerical approaches combining propagation and bioelectromagnetics will be realized to assess both fields and absorptions in realistic 3D environments.
