Abstract :
The aim of this study is to achieve experimental estimation of whole-body averaged specific absorption rate (WB-SAR) of human models using theradiation-field scanning technique. The original relationship between the WB-SAR and the reference level of ICNIRP Guidelines [1] was obtained through the theoretical analyses using the simple geometrical or block structure. Recently, high resolution numerical simulations have become possible through the use of highspeed computers and high accuracy human phantoms based on magnetic resonance imaging [2], [3]. On the other hand, some experiments to investigate the same subject have been reported [4]. It is very important to obtain reliable measurement data that can contribute to the validation of recent precise computation-based estimations.
