Evaluation and SAR Analysis of Low Frequency and Broadband Electric Field Exposure Measurement Values in the Home Environment

In this study, the effective value of low frequency (50 Hz) and high frequency (700-2500 MHz) broadband electric field exposures were measured for 24 hours in four different selected environments in a house. All statistical values of 1000 data recorded with two measuring devices for 24 hours 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 (Ԑr) and conductivity (σ) of each layer into consideration. The specific absorption rate (SAR) value in the brain is calculated by using total transmission coefficient of six layers. 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 the SAR limits.
