Electromagnetic fields (EMFs) produced by man-made devices are all around us. Especially with the next generation of radiofrequency EMFs, further investigations regarding EMF and possible health risks are required. In this context, the EU-funded NextGEM project will generate relevant knowledge of EMF exposure in residential, public and occupational settings. The project will design a new framework for the generation of health-relevant scientific knowledge and data on new scenarios of exposure to EMF in multiple frequency bands. Its overall aim is to provide a healthy living and working environment, under safe EMF exposure conditions.
