The rate of the radiofrequency energy deposition in a model of the human body exposed in the near-field of a resonant dipole at 350 MHz was calculated using the moment method. Detailed maps of the electric field intensity in a similar model under the same exposure conditions were obtained using a computer-controlled scanning system and an implantable electric field probe. A comparison of the measurement data with the theoretical predictions shows a relatively good agreement when average values over relatively large volumes are concerned, however the calculations fail to predict large gradients and tend to underestimate the magnitude of 'hot spots'.
