Key Points Standards are set to protect our health and are well known for many food additives, for concentrations of chemicals in water or air pollutants. Similarly, field standards exist to limit overexposure to electromagnetic field levels present in our environment.
Countries set their own national standards for exposure to electromagnetic fields.
This non-governmental organization, formally recognized by WHO, evaluates scientific results from all over the world. These guidelines are reviewed periodically and updated if necessary. Electromagnetic field levels vary with frequency in a complex way. Listing every value in every standard and at every frequency would be difficult to understand. These guidelines were last updated in April 1998.
