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!

Man-made radio frequency fields

While low frequency alternating fields are mainly generated as a side effect of the transmission and use of electrical energy, radiofrequency electromagnetic fields are usually produced intentionally for transmitting information. In addition, low frequency and radiofrequency fields are also used for therapeutic and diagnostic applications. On the earth, also occur, on a small scale natural radiofrequency electromagnetic fields (Natural radio frequency fields).
