radio frequency

Synonyms:
  • RF
Electromagnetism. Any frequency in the range 1 MHz - 300 GHz.
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, neurons and sensory receptors may occur. Above 1 MHz only thermal effects have been scientifically proven yet.
In other context, radio frequency refers to the frequency range 100 kHz - 300 GHz.
