RFexposienormen

RFexposienormen are standards and guidelines that define safe levels of exposure to radiofrequency RF electromagnetic fields for humans. They aim to protect health in everyday environments and in workplaces, covering a broad range of frequencies from low to high microwave bands.

Exposure limits are typically distinguished for occupational exposure (people working near RF sources) and general public exposure. Measurements are expressed as specific absorption rate (SAR, watts per kilogram) for localized exposure, and as field strength, power density, or whole-body SAR depending on frequency and scenario. Assessments combine measurements with computational modelling and tissue phantoms to simulate how RF energy is absorbed by the human body.

Key international references include the ICNIRP Guidelines on limiting exposure to non-ionizing electromagnetic fields, which have guided national regulations since their publication (most recently updated around 2010). National regulators, such as the FCC in the United States and European authorities, implement these guidelines through law or regulation, sometimes adapting limits for specific bands or exposure contexts. The IEC and IEEE provide standards for measurement methods, dosimetry, and related testing protocols.

Practical implications of RFexposienormen include mandatory testing of mobile devices for SAR before market release, labeling and documentation requirements, and workplace risk assessments to ensure compliance with exposure limits. The topic remains subject to ongoing research and periodic updates as new technologies and exposure data emerge, influencing how regulators translate guidelines into national rules.
