Electromagnetic waves are produced whenever charged particles are accelerated, and these waves can subsequently interact with other charged particles. Living systems, including the human body are composed of charged and polar molecules that use their electromagnetic properties physiologically. Indeed without these intrinsic natural electromagnetic forces, life could not exist.
The effects of EMR upon biological systems depends upon the radiation’s properties such as power, intensity, modulation, waveform, and polarisation, exposiometry (dosing characteristics, including cumulative dose), properties of the tissues being exposed, presence or absence of synergistic toxins, and health status of the organism being exposed.
Therefore it is impossible to predict biological interaction in detail in the complex situations of real life, and it is clear that some individuals will be more vulnerable than others to negative health effects. Equally, some species are likely to be more vulnerable than others, and EMR can have biological effects in all species as we would expect.
