ABSTRACT: The international recommendations and standards for the radiofrequency (RF) dosimetry of the human body use the body-averaged specific absorption coefficient (WBA-SAR) as an approximate indicator for measurement of increase of the body temperature. We propose the analytical-numerical approach to analyze the RF dosimetry of the human grounded body. The body being in a far zone is irradiated by the plane EM field; the considered frequency range is 1 - 200 MHz; the approach is based on a cylindrical antenna model. The human body is represented by a homogeneous cylindrical monopole antenna with losses. The model allows studying the influence of body mass, human height and dielectric properties of body components on the WBA-SAR values.
