Computer simulation of human head irradiation by a cell phone field

Abstract

Communication systems are developing at an incredible speed. This also applies to mobile communication systems, which today are among the most important telecommunication systems operating at microwave frequencies. Working mobile phones are sources of non-ionizing radiation near the head or body. Despite the fact that the average person spends several conversations on a cell phone every day, the issue of the impact of radiation on health has not yet been fully studied. Simulate the effect of cell phone radiation on biological tissues of the human body, in particular on the head. Two computer models of the human head have been built. Computer simulation of the effect of cell phone radiation on biological tissues of the human body has been performed. An important feature of the model is the presence of layers with different parameters. The layers correspond to real biological tissues (skin, adipose tissue, muscle, skull and brain). A study of the field distribution in the volume of the human head, induced by a working mobile phone, is presented. The specific absorption coefficient was determined. Shown is the thermal effect caused by exposure to radiation from a mobile phone. In the case of the multilayer model, lower values of the specific absorption coefficient were obtained, which can be explained by the use of a more accurate computer model. It became possible to graphically represent the propagation of electromagnetic waves through the head model. The temperature distribution over the surface and in the volume of the human head is illustrated.
