“…The electromagnetic field created by transformers and high-voltage lines in certain public areas in Konya (Turkey) city center was measured, and the results were compared with the limit values [24]. To find the SAR value of the electromagnetic field emitted by mobile phones in the human heart region, the values obtained by electrically modeling the heart were analyzed using the finite difference time domain method (FDTD) using MATLAB and compared with the limit values [25]. It is known that exposure to a non-ionizing electromagnetic field increases the temperature of cells in the human body, and its limits are determined in this way.…”

In this study, the effective value of low-frequency (50 Hz) and high-frequency (700–2500 MHz) broadband electric field exposures was measured for 24 h in four different selected environments in a house. All the statistical values of 1000 data points recorded with two measuring devices for 24 h in each environment are calculated, the most appropriate curves are fitted to the data, and the curves are plotted by expressing their changes with respect to time. All statistical and parametric values of the density and cumulative probability functions of the curves are calculated and plotted. In broadband measurements, the broadband is divided into fifteen sub-bands, but the data are available in only six of these sub-bands. The six-layer human head model is created by using the middle frequencies of the six sub-bands used, and taking the permittivity (εr) and conductivity (σ) of each layer into consideration. The specific absorption rate (SAR) value in the brain is calculated by using the total transmission coefficient of six layers. The SAR value surrounding the head is obtained. These SAR values are interpreted by considering the Federal Communications Commission (FCC) and the Community European (CE) occupational and general public SAR limits.
