Electromagnetic fields (EMF) are one of the main types of physical pollution of the environment in urban lands. The danger of adverse impact of EMF on human health increases with growth of electric power consumption. Therefore, the issues of protection of the population against EMF impact are becoming very important. One of the options for protection against EMF exposure is the use of reinforced concrete fences with shielding properties. Despite the simplicity of such a device against EMF, it can be stated that shielding effect assessment issues are poorly known. The objective of this paper is to assess the shielding effect of reinforced concrete fences in EMF industrial frequency. The shielding effect of the reinforced concrete fences study was conducted on the surrounding area of the thermal power plant (TPP), located on the edge of Mytishchi city of the Moscow Region. The effects of an abrupt increase in the EMF intensity in front of the reinforced concrete fence and its decrease behind the fence are revealed. It is found that these effects are associated with the concrete reinforcement impact inside the fence, in which an alternating electric current is generated. The shielding effect determines the partial reflection of EMF in front of the fence and decrease of EMF inside it. Accounting for the shielding effect of reinforced concrete fences provides perspectives of organizing the protection of the population near residential and industrial buildings, as well as protection of personnel working in the strong EMF areas.
