Do different forms of Electromagnetic Fields (EMFs) have different health concerns?

An Electromagnetic Field (EMF) is defined by the frequency and corresponding wavelength. The frequency is expressed as cycles per second, or the number of oscillations. The corresponding term, wavelength, is the distance between each of the waves. It is also true that the higher the frequency, the shorter the wavelength. The human body reacts in different ways depending on the EMF frequency, and a higher frequency doesn’t necessarily mean that frequency is more harmful to the body. Devices and wireless signals emit frequency levels at the lower end of the electromagnetic spectrum, from 0 Hertz (Hz) to 100 Gigahertz (GHz). As the frequency level increases, this yields a higher absorption (SAR level) but a lower penetration into the body. This means that as frequency levels change, health concerns change.
