Analysis of Human Exposure to Base Station Antennas Radiation

Electromagnetic– thermal analysis of human exposure to base station antennas radiation is presented in this article. The formulation is based on a simplified cylindrical representation of the human body. Electromagnetic analysis involves incident and internal field dosimetry, while the thermal model deals with the bio-heat transfer phenomena in the body. The electric field induced in the body is determined from the axial current distribution inside the body. This current distribution is obtained along the body obtained by solving the Pocklington integral equation via the Galerkin– Bubnov Boundary Element Method. Once the internal electric field and related total absorbed power in the human body is obtained, a related temperature rise in the body due to the Global system Mobile exposure is calculated. This temperature rise is determined by solving the bio-heat transfer equation via the dual reciprocity boundary element method, and is found to be rather negligible.
