Biological effects and health implication of radiofrequency and microwave

Abstract

Low level electromagnetic fields have been found to produce a variety of biological effects, though the mechanism of such interactions is still not completely understood. The cell membrane of the brain is a critical structure perceiving the action of microwaves, which has received greater attention. The interactions of EM fields with living cells are considered for stochastic resonance, cooperative effects, non-equilibrium thermodynamic processes and nonlinear interactions. The nonlinear mechanism plays the main role in the process of transmembrane coupling of the signal to the cytoplasm. The criteria for safe exposure limits of an electromagnetic field to humans is also discussed.
