Due to a lack of financial resources, we unfortunately have to suspend the import of any new radio frequency and mobile phone-related articles as of now (November 27, 2017). We apologize for this inconvenience and will keep you informed.

Because we received a large number of inquiries, we set up a bank account to accept donations. With their aid, we hope to resume, at least partly, the import of newly published articles to the RF archive of the EMF-Portal. Any contribution is greatly appreciated. Thank you for your kind support!

low frequency

  • LF
Electromagnetism. Any frequency in the range of 0 Hz - 100 kHz.
The classification of non-ionizing electromagnetic fields into low frequency and radio frequency is made according to scientifically documented interaction with the organism. Below a threshold of 1 MHz stimulation or excitation effects of nerves, muscles, and sensory receptors may occur. Above 1 MHz only thermal effects have been scientifically proven yet.
In other context, low frequency refers to the frequency range 0 - 100 kHz.
