Electromagnetic fields are omnipresent in daily life. They can arise as a by-product of the generation, transport and use of electricity. They can also be deliberately generated to heat materials or transmit information. RIVM conducts scientific research on exposure to electromagnetic fields, their possible health effects and risk perception and communication. RIVM also provides scientific advice and support to policy makers, mainly at the ministries responsible for public policy on sources of electromagnetic fields and their inspectorates (Infrastructure and Environment, Social Affairs and Employment, Economic Affairs, Health). RIVM also participates in international scientific organisations that evaluate the risks of electromagnetic fields.
