[Utilisation de modèles de femmes enceintes simplifiés pour analyser lʼexposition du fœtus]
Dans cet article, nous présentons une étude destinée à valider lʼutilisation dʼun modèle simplifié de femme enceinte pour analyser lʼexposition aux ondes radiofréquences du fœtus. Ce modèle simplifié, construit en remplaçant la plupart des organes internes de la mère par un tissu homogène, nous permettrait de nous affranchir de plusieurs problèmes qui se posent avec les rares modèles de femme enceinte dont nous disposons pour la dosimétrie numérique. En comparant des debits dʼabsorption spécifique, on montre que lʼutilisation dʼun modèle semi-homogène est pertinente pour lʼestimation de lʼexposition du fœtus à une onde plane.
In this paper, we introduce a study that we carried out in order to validate the use of a simplified pregnant woman model for the assessment of the fetus exposure to radio frequency waves. This simplified model, based on the use of a homogeneous tissue to replace most of the inner organs of the virtual mother, would allow us to deal with many issues that are raised because of the lack of pregnant woman models for numerical dosimetry. Using specific absorption rate comparisons, we show that this model could be used to estimate the fetus exposure to plane waves.
