Abstract: The Exposure to electromagnetic fields is not a new phenomenon. However, during the 20th century, environmental exposure to man-made electromagnetic fields has been steadily increasing as growing electricity demand, ever-advancing technologies and changes in social behavior have created more and more artificial sources. The general opinion is that there is gradual hazardous effect at the cellular level related to human health. The study of the low frequency radio frequency wave reveled that different dimension of EM wave have not shown any DNA damage directly hurt there is concern about evidence of cellular effect of EM.
