The EMF-Portal | Technology section offers comprehensive information on electromagnetic fields, sources, and their effects. It covers static, low, intermediate, and radio frequency fields, including applications like mobile communications, MRI, and therapeutic uses, facilitating scientific research and risk assessment.
The EMF-Portal provides an extensive, scientifically structured overview of electromagnetic fields (EMF) and related technologies. It covers various types of fields including static fields (0 Hz), low frequency (0.1 Hz–1 kHz), intermediate frequency (1 kHz–10 MHz), and radio frequency (10 MHz–300 GHz). Each frequency range is further divided into natural and man-made sources. The portal addresses key technologies such as power generation and distribution (including overhead lines, underground cables, substations, and traction power systems), high-voltage direct current (HVDC) converter stations, magnetic resonance imaging (MRI), induction hobs, electric vehicles, wireless chargers, and mobile communication systems including 5th generation mobile communications (5G) and broadcasting transmitters. The EMF spectrum is discussed historically and in detail, emphasizing both electric and magnetic fields. It also catalogs exposure sources relevant in both industrial and domestic environments. Additionally, the portal references population and experimental studies analyzing various biological effects, including genotoxicity, electromagnetic hypersensitivity, neurodegenerative diseases (e.g., Parkinson’s, Alzheimer’s, ALS), cancer including childhood leukemia, modifications of brain waves, cardiovascular impacts, melatonin secretion, and cognitive functions. Therapeutic applications and indirect effects are also presented. A comprehensive glossary and links to national and international EMF-related institutions support the evaluation of limit values and risk assessment procedures. These include limit values for public and occupational exposure, background information, and international comparisons. The portal also addresses risk communication strategies and injury mechanisms related to electric currents. Overall, the EMF-Portal serves as a multifaceted resource integrating scientific literature, technology descriptions, health effect evaluations, and regulatory frameworks relevant to electromagnetic field exposure and technology.
