Whole-body SAR in spheroidal adult and child phantoms in realistic exposure environment

In the past, the absorption of electromagnetic fields in a human body has been studied for a homogeneous worst-case single plane wave exposure or for a deterministic heterogeneous exposure, i.e. a measured incident electric field distribution. The work presented in this report, investigated the absorption in homogeneous spheroidal human body phantoms in a realistic exposure environment for frequencies ranging from 150 to 950 MHz using a statistical multipath exposure tool. The absorption has been investigated for five different sizes of the spheroid model. It is reported that the highest absorption occurs in the smallest phantom and that the ICNIRP reference levels do not satisfy the absorption limits for a realistic exposure scenario. Therefore, ICNIRP reference levels should be adapted to provide compliance to the basic restrictions for realistic exposure scenarios.
