Abstract
The topic of the research presented in this paper is numerical calculation and analysis of the electric field and Specific Absorption Rate (SAR) distributions in the vicinity of dental amalgam exposed to the radiation of mobile phone at the frequencies corresponding to 3G and 4G mobile networks. This is carried out by numerical solving of the electromagnetic propagation equation. The results related to different tissues and organs placed in the vicinity of dental amalgam and exposed to radiation are presented and analysed. In order to obtain the most accurate results, the realistic 3D model of human jaw has been created. A comparative analysis of models with and without dental amalgam has been carried out, with aim to determine the impact of amalgam on biological tissues in its vicinity. According to the obtained results, the maximum values of electric field strength and SAR are higher in the presence of dental amalgam. In both cases, maximum values are out of bounds of safety limits.

According to the obtained results presented in the previous Section, it is shown that the electric field maximum value in the vicinity of dental amalgam exposed to the mobile phone radiation is higher in a presence of dental amalgam than without it
Summary
In the last few years, mobile phones and communication systems as well have been developing at an astounding rate. Due to numerous advantages and opportunities, one can observe the massive growth in the usage of mobile phones, including the time spent using them. This brings significantly increasing exposure to electromagnetic radiation caused by a cell phone, which turned the focus towards researching the impact of electromagnetic waves on human organism and estimation of human health risk. The cell phones, as nonionizing electromagnetic radiations sources placed in the vicinity of the human head, should be considered as the potential health hazards. The corresponding safety measures prescribing maximal allowable values for electromagnetic field exposure have been included in published safety standards and recommendations [1]–[4]. It is necessary to emphasize that electromagnetic field has been characterized
