Abstract (in Japanese) (See Japanese page) 
(in English) The present safety limits all over the world are being determined based on the behavior destruction of healthy adult animals for radio-frequency (RF) exposure, which are not being obtained for young or pregnant animals. Because of this reason, we think that it is necessary to study more absorption properties in pregnant woman with fetus and their correlation for electromagnetic wave exposure. In this study, we calculated the whole-body-average specific absorption rates (WBA-SARs) in an anatomical model for pregnant woman together with the WBA-SARs in fetus and other organs for vertically polarized far-field exposure, and examined their correlations. As a result, we found that 70 MHz exposure provides a negative correlation between inner organ average SARs and their weight, and 400MHz and 1GHz exposure give a strong negative correlation with average depth from the body surface for RF exposure. This implies that average depth from the body surface and fetus weights with respect to growth are important indices in evaluating the whole-body average SARs in fetus.
