Fetus RF exposure analysis. Preliminary results based on three realistic 3D digital models
Résumé
Mobile phones have been increasingly used over the 30 last years. The versatile use of personal Digital Assistant (PDA) is strengthening this tendency. In spite of existing protection limits (ICNIRP, IEEE) there is worldwide a public concern about the exposure to electromagnetic fields (EMF). Several expert groups have pointed out the need of research dedicated to children, pregnant women and fetus exposure. Recently the World Health Organization (WHO) has recommended the study of the EMF dosimetry onfetuses as a high-priority research topic. The estimation of the Radio frequency (RF) fetus exposure induced by wireless communication systems is complex since new technologies can be used in versatile ways and since the exposure depends on many parameters (usage, frequency, posture, age of fetus…). The exposure assessment of fetuses is facing 3 major challenges. The first challenge is the limited number of existing anatomically corrects models of mother and fetus that can be considered reliable for the exposure assessment. The second challenge is the lack of tools allowing deforming the fetus and mother models in a correct anatomical way. The third challenge is the management of the complexity of this problem to assess the statistical distribution of the exposure and consequently the maximum exposure.The FETUS project, granted by ANR in France and JST in Japan, is dealing with these ambitious challenges. In this paper we present the works performed within this project to characterize the RF fetus exposure to far field exposure modeled using plane wave.
