Abstract

Overview

The continuous development of Radio-Frequency (RF) devices in everyday life necessitates detailed health risk assessments, specifically focusing on fetal exposure to RF Electromagnetic Fields (RF-EMF) under realistic conditions.

Methodology

This research employs stochastic dosimetry, a technique incorporating electromagnetic computational methods and statistical analysis, to evaluate fetal exposure to a 4G LTE tablet. The study factors in the tablet’s position, the fetus's gestational age, and the emission frequency of the device.

Findings

  • The Specific Absorption Rate (SAR) levels observed were within the safe limits set by the ICNIRP 1998 guidelines across various scenarios.
  • The tablet's position significantly affected SAR levels in the fetus, with a Quartile Coefficient of Dispersion consistently exceeding 40%.
  • Exposure levels were notably higher in later stages of pregnancy compared to earlier stages.
  • A higher frequency from the emitting antenna correlated with a lower SAR in the fetus.

Conclusion

Although SAR levels stayed within international safety standards, the position of the device and the frequency of emissions substantially impact fetal exposure, indicating the need for careful management of device use during pregnancy.
