Abstract

Abstract Summary of Research on RF Emissions from Mobile Base Stations

Overview

The last two decades have witnessed an increased prevalence of macrocell mobile telephony base station antennas in residential areas, primarily emitting radiofrequency (RF) electromagnetic radiation (EMR). This shift has intensified concerns and focus on the potential health implications of RF EMR.

Methodology and Findings

• The study involves scientific field measurements of the public exposure to RF EMR specifically from these antennas.
• Assessment of RF electromagnetic field (EMF) intensity in accessible areas was conducted adhering to safety norms and Lithuanian Standards (LST EN).
• Experiments included broadband and frequency-selective measurements in various setups: directly in front of antennas, on rooftops, on the ground, and within residential vicinities.
• Near-field measurements highlighted a dynamic energy interaction in the antenna's electric field, altering rapidly with distance.
• Power density measurements at varying distances (50m to 500m) from the base station showed extremely low RF EMF levels, ranging from 0.002 to 0.05 μW/cm², aligning well within international exposure guidelines (ICNIRP).

Conclusions

This detailed examination of RF emissions from mobile telephony base stations confirms low levels of RF electromagnetic power density in public access areas, suggesting adherence to accepted safety exposure limits. Continued monitoring and research are advised to further validate these findings and address public health concerns.
