Summary:
The aim of this study is to achieve experimental estimation of whole-body averaged specific absorption rate (SAR) of human models using the radiation-field scanning technique. The relationship between the reference level of ICNIRP Guidelines [1] and the whole-body averaged SAR was established mainly based on numerical calculations for highly simplified human modelling. Recently, many dosimetry estimations for human exposure including high accuracy numerical phantom models have been reported [2]. However, due to the difficulty of the measurement in the whole human body exposed by RF plane-wave, there have been a few experimental investigations based on calorimeter or thermography method [3]. It is very important to obtain reliable measurement data that can contribute to validity analyses for the recent precise computational estimations. Previously, we proposed a new whole-body averaged SAR estimation method based on electric power consumption based on the cylindrical field scanning technique [4]. In this paper, we develop the experimental set-up for whole-body averaged SAR estimation using human phantom made of tissue-equivalent material and scaled model. Additionally, measured results of whole-body averaged SAR of standing human for 2GHz far-field exposure are shown.
