RF-EMF Exposure Assessment of Fetus During The First Trimester of Pregnancy
Abstract
Overview
This study focuses on the computational analysis of Radio Frequency - Electromagnetic Field (RF-EMF) exposure in Uterus-Fetus Units (UFUs) of a 26-year-old human female during the first trimester of pregnancy.
Methodology
- Development of realistic UFU models based on ultrasound images for fetuses at 7, 9, and 11 weeks.
- Employment of a deep-learning based segmentation method.
- Use of a computational electromagnetic model of a 26-year-old female.
Findings
The Specific Absorption Rate (SAR) of the fetus was estimated at commonly used wireless communication frequencies using a numerical electromagnetic solver.
- The Inverted F antenna (IFA), used in mobile phones, served as the excitation source.
- Fetus SAR values were calculated under various conditions and found to be well within safety limits set by ICNIRP.
Comparative Insights
Additional tests compared SAR values between the fetus and equivalent uterus tissues, revealing only marginal differences.
Conclusion
Overall, the RF-EMF exposure to the fetus is noted to be minimal, ensuring safety under the tested conditions.
