The availability of efficient, reliable and reasonably simple procedures providing assistance in evaluating human exposure to radiofrequency fields from base station antennas is essential for mobile communications. In this paper, sample results of "rigorous" full-wave numerical analysis of the electromagnetic field morphology in vicinity of a typical representative base station panel antenna are presented. Secondly, having recognized the EM field morphology, two approximate formulas for the radiated power density calculations are compared and their accuracy and range of applicability is discussed. Finally, an attempt is made to estimate the specific absorption rate and the total absorbed power in a simple box-shaped phantom placed in close vicinity of the antenna.
