In this paper, an analysis of the surface electric field on a human body based on finite-difference time-domain simulations is presented. A statistical analysis of the dosemeter interaction with the human body has been made by means of the variations of the relative orientation of the human body from the RF source. Variations of the RF source frequency have also been made, by comparing three different services FM, GSM-900 and DCS-1800. Three different scenarios have been simulated where the angle of arrival of the main RF contribution impinges on the human body with a certain probability. Despite the differences between the scenarios, the variations in the electric field strength at each frequency are negligible where the dosemeter would be located.
