Abstract

Overview

As electronic applications become more prevalent, public concern over potential health risks associated with radiofrequency exposure is increasing. This study provides an in-depth analysis of methods used in large-scale evaluations of radiofrequency exposure.

Methods

The assessment divided sites into three categories for evaluation: commercial areas, urban residential areas, and rural residential areas. Data was gathered using a car-mounted system over the course of two years (2014 and 2015) to characterize the electric field exposure from various radiofrequency sources.

Findings

• The results confirm that the environments studied were within safe exposure limits according to guidelines and standards.
• The highest exposure recorded during this period was from an FM source, measuring 316.23 mV/m.
• Telecommunication sources were identified as the major contributors to exposure, accounting for 65-90% of the power density.
• Spatial distributions of FM and GSM1800 exposure were mapped to show detailed exposure patterns.

Conclusion

The study not only provides a methodological foundation for assessing radiofrequency exposure but also assists in pinpointing any significant sources of exposure beyond acceptable standards. This facilitates ongoing monitoring and management of EMF exposure risks.
