EMR spectrum principle

Abstract

The electromagnetic spectrum has a very wide range of frequencies. Understanding how these various frequencies interact with human bodies is very important for appreciating how these signals and fields can cause biological effects when tissues or whole bodies are exposed. Biophysics is a very important scientific discipline for understanding how the natural body electromagnetic and biological systems work and how external signals from extremely low-frequency fields and radiofrequency and microwave radiation enter into and interact with the body systems and cells. The basic physics principles involved are resonance interaction and absorbance, and energy conversion and conservation. The failure to understand these principles leads to errors in the setting of standards and the inappropriate interpretation of epidemiological results.
