A numerical model of a human body with an intramedullary nail in the femur was built to evaluate the effects of the implant on the current density distribution in low frequency electric and magnetic fields. The intramedullary nail was chosen because it is one of the longest conductive implants used in medicine. The results show that the implant significantly increases the current density in locations where it is in contact with soft tissue. This implies that the existing safety limits do not necessarily protect implanted persons to the same extent as they protect people without implants.

We used an FDTD simulation to evaluated the combined EMF exposure of an anatomical human model in front of a 3-band panel base station antenna with simultaneous exposure at 900, 1800 and 2100 MHz. In the realistic exposure scenarios we considered, none of the separate frequencies exceeded the basic restrictions, even at the shortest distance investigated. The results also show that with simultaneous exposures to several frequencies, the whole-body SAR reaches its basic restriction at a larger distance from the antenna than the spatial-peak SAR.
