Analysis on shielding effectiveness of electromagnetic field of building components in the range of communication networks fields

We are exposed electromagnetic radiation anytime and everywhere. However, during the 20th century, environmental exposure to man-made electromagnetic fields has been steadily increasing with growing electricity demand, ever-advancing technologies and changes in social behaviour have created more and more artificial sources. The quantity of the electromagnetic field is increased. This trend is likely to continue. This paper consists of two parts. Tiny electrical currents exist in the human body due to the chemical reactions that occur as part of the normal bodily functions, even in the absence of external electric fields. We present the influence of RF field exposition on biological samples during short-time period tests in first part this article. The exposition was carried out in…
