Specific absorption rate in human fetus with fetal growth for RF far-field exposure

The adverse health effects of radio-frequency electromagnetic fields have become of increasing concern. We conducted a specific absorption rate (SAR) dosimetry study of pregnant females and their fetuses at various gestational ages. We developed novel pregnant female models with anatomically realistic fetal and gestational tissues at 20, 26, and 29 weeks of pregnancy. In this paper, we present the modeled SAR characteristics of pregnant females and their fetuses exposed to vertically and horizontally polarized EM waves from 30 MHz to 3 GHz at the three gestational ages.
