Experimental Determinations Regarding the Efficiency under Electromagnetic Shielding of Certain Construction Materials

Once with the development of production, distribution and use of electricity, the first aspects regarding the effects of electromagnetic radiation over the human health have emerged. The fast development of electronic equipments (laptops, monitors, televisions, mobile telephony, wireless data transmission equipment, radar antennas, etc.) during the last decades has led to new interdisciplinary studies and researched regarding the short, medium and long term effects of electromagnetic radiation over the human health. A significant aspect to be studied from this point of view as well as from the safety of wireless data transmission is the study of how materials used in the architectural field of interior and exterior behave with respect to the electromagnetic field radiation. In this paper are presented certain experimental determinations made with high performance equipments that belong to the electromagnetic compatibility laboratory within ICMET-Craiova, on certain materials used in constructions (DEBOND, Polycarbonate, Fireproof polypropylene and gypsum board). The experimental results have showed that the materials studied, except for the DEBOND material which contains a thin sheet of aluminum (Al) in its composition, unfortunately do not provide a good efficiency under electromagnetic radiation.
