SAR and thermal distribution of pregnant woman and child inside elevator cabin

Abstract

Overview

This study explores the electromagnetic absorption and thermal effects when a mobile phone is used inside an elevator cabin, particularly affecting a 7-month pregnant woman and a 5-year-old child.

Methodology

Numerical human models of the pregnant woman and child are employed, with the child acting as the phone user. The phone is tested in three different positions — parallel, tilt, and cheek — at frequencies of 1000 MHz and 1800 MHz.

Findings

• The child's exposure to radiofrequency (RF) radiation varies significantly with the phone's position, while the pregnant woman's fetus is primarily affected by the models' relative positions.
• SAR values and temperature rises are analyzed, emphasizing the settings within a metallic elevator cabin.

Conclusion

This research highlights the heightened vulnerability of pregnant women and young children to RF exposures in enclosed metal environments, such as elevators, particularly when using mobile phones.
