Investigation of Microwave Electromagnetic Fields in Open and Shielded Areas and Their Possible Effects on Biological Structure

Abstract

Overview

The study examines the presence and implications of electromagnetic fields (EMF) within the microwave frequency band, particularly in environments shielded from external EMF sources such as elevator cabins and cars, frequented in daily life. The intention is to measure and compare these values against accepted health standards.

Findings

• Measurement of specific vector quantities of EMF was performed.
• Shielded areas showed increased EMF levels compared to open areas.
• Calibration and verification of measurements were conducted using different types of antennas.
• The EMF levels in shielded spaces did not surpass the thermal effect limitations on living tissues.

Conclusion

Results indicate that while EMF values in shielded spaces are elevated, they do not exceed current health standards. Notably, EMF can potentially interfere with the operation of medical devices like pacemakers under specific conditions (e.g., multiple simultaneous mobile phone uses in an elevator). Caution is recommended concerning mobile device usage in such environments.
