Summary:A fast method to assess radiofrequency (RF) radiation absorption in humans present in realistic indoor environments is proposed. The only required inputs are the room characteristics and the weight and position of the human with respect to the electromagnetic source. The method is compared and validated with full finite-difference time-domain simulations. Various realistic scenarios are investigated, in which one to six human phantoms are present. Whole-body power absorption ranges from 23.5 to 85.9 µW kg with a median deviation of ∼3.1 dB (51 %). While this difference may appear large, it is outbalanced by a calculation time of less than a second for the proposed method compared with ∼17.5 h for a single full-wave electromagnetic simulation.
