Bio-Interaction Mechanism of Occupational Extremely Low-Frequency Magnetic Field and its Potential Effects on Human

Human lifestyle is evolving as a result of advancement in technology which is mainly driven by electricity. The presence of extremely low frequency magnetic field in the Earth’s atmosphere produced during the processes of generation, transmission and distribution of electricity in occupational environment has the ability to penetrate human skin, and is potentially hazardous to health of exposed individual, which have become a source of concern. This article presents state of knowledge on the electrical and dielectric properties of human tissues, examine the various phenomena processes during the bio-interaction mechanism, all-inclusive biological effects process explained and identify potential health risk associated with prolonged and excessive exposure to occupational magnetic field at extremely low frequency in addition to the underlining factors that influence the probable threats.
