What is radiofrequency radiation?
Radiofrequency (RF) fields are part of the electromagnetic (EM) spectrum. The EM spectrum is divided into ionizing and non-ionizing bands based on how the wave interacts with biological tissue. The non-ionizing portion, usually in the frequency range up to 300 GHz, doesn’t affect biological tissue and includes the extremely low frequency (ELF) band, radio waves and microwaves in the radiofrequency communication band, and infrared and visible light. The RF part of the spectrum is usually defined as being between 30 kHz and 300 GHz. RF radiation is mainly used in telecommunications. Mobile phones employ frequencies in the range of 800 MHz to 2GHz. Other uses of RF energy include microwave ovens and medical treatments. The ionizing portion of the EM spectrum (made up of ultraviolet light, gamma rays and X-rays that have very short wavelengths, very high frequencies, and very high intensities) does affect biological tissue. Mobile phones do not operate in this spectrum. For more on this, s
