Abstract (in Japanese) (See Japanese page) 
(in English) For the purpose of exposure assessment in epidemiological studies on RF exposure and brain tumor risk, SAR distributions in different anatomical structures of the brain of a realistic numerical model were estimated for different use conditions and phone categories. Our results suggested that the maximum SAR is always obtained in the temporal lobe and that the temporal lobe is generally the highest exposed anatomical structure, except for special types of phones with an absorption localized at the back of the head, which makes the occipital lobe and the cerebellum the highest exposed structures. Occipital lobe and cerebellum were for almost all use conditions and phones categories either the first or the second exposed structures whereas exposure of parietal and frontal lobes were usually low. We nuanced our results with the fact that we used measurements in an homogeneous phantom to estimate SAR in an heterogeneous model.
