Numerical modeling and dosimetry of pregnant females at various stages of pregnancy

Exposure to radio-frequency electromagnetic (EM) fields has become an important issue in preserving human health. In particular, conducting numerical dosimetry on the mother and fetus during pregnancy has become an important issue. 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 electromagnetic waves from 30 MHz to 3 GHz at the three gestational ages.
