Abstract

Thermal effects of radiofrequency EM field exposure on humans were studied. The only acceptable and reliable way to study the effects of electromagnetic fields on biological bodies such as humans is computer simulation using numerically realistic models (or phantoms). The method of study is the finite difference time domain (FDTD) method. Based on numerical experiments performed by the FDTD LAB program, the average SAR values ​​in a female whole body model and the temperature response (ΔT) caused by the absorption of EM field energy were determined. The compliance of the results with safety limits was also studied; Possible risks were assessed based on the amount of absorbed energy and the corresponding ΔT value.
