What are the effects of RadioFrequency (RF) on the human body ?
Radio frequency (RF) fields transfer energy to tissues primarily in the form of heat, resulting in what is known as thermal effects. This is particularly prominent in the microwave region, which falls between the upper range of radio waves and infrared radiation. The microwave region spans from approximately 1 GHz (or 1000 MHz), corresponding to a wavelength of 30 cm, to about 300 GHz, which corresponds to a wavelength of 1 mm. In this frequency range, the energy is mainly converted into heat in the tissues.
On the other hand, low-frequency fields (ELF), which have a slowly varying frequency, induce currents within the human body. These currents are a result of the interaction between the body and the ELF fields.
In addition to the thermal effects caused by radio frequency electromagnetic fields, there has been a growing awareness of non-thermal biological effects resulting from these fields in recent decades. These effects include the potential to induce carcinogenesis, among others. It is not surprising to observe these effects since the electric fields associated with modern radiofrequency fields are higher than the average cellular activity potential, which typically ranges between 100 and 200 mV (and can reach up to 1 V in stressful situations).
