Investigation of Specific Absorption Rate (SAR) near model of fetus in uterus

Abstract

Overview

This study focuses on the effects of electromagnetic fields (EMF) on models that represent different stages of pregnancy, including a model in the first trimester and a model of the fetus at 35 weeks. The major contrast in specific absorption rate (SAR) levels between these models and the AustinWoman model in an open area is explored.

Methodology

Using finite integration method for EMF modeling, simulations were performed with a pregnant woman model in open space using a cell phone. Two types of antennas—a dipole antenna at 2.4 GHz and a planar monopole antenna—were employed as radio frequency sources.

Findings

• The study measures electromagnetic energy absorption within these human models.
• Variations in SAR levels were noted based on different antenna types and their proximity to the models.
• Some scenarios exceeded the SAR limits set by international standards, indicating potential risks.

Risks and Conclusion

Our findings suggest significant implications for fetal exposure to EMF, particularly in the first trimester of pregnancy, where vulnerability is heightened. These discrepancies in SAR levels highlight the necessity for stringent adherence to EMF exposure limits to protect against potential long-term health effects.
