Electromagnetic intensity investigation of emitted non-ionizing radiation from base transcriptive stations in the urban region of southern Iran

Abstract

Overview

This study focuses on the assessment of electromagnetic intensity (EMI) emitted from base transcriptive stations (BTS) located within the urban region of southern Iran. Monitoring EMI in such environments is crucial for both policymakers and the general population due to potential health risks associated with exposure.

Methodology

• EMI measurements were conducted at 30 BTS locations at distances less than 20 meters and more than 200 meters from the source.
• Data was collected during both summer and winter seasons using SMP2-dual real-time equipment.

Findings

• Measured EMI in summer ranged from 2 to 6500 mW/m², higher than the winter range of 1.5 to 5000 mW/m².
• Notably, about 93% of samples surpassed the World Health Organization (WHO) recommended standards for EMI exposure, highlighting a significant safety and health risk link.
• There was a clear decrease in EMI with increased distance from the BTS.
• A negative correlation was found between temperature and EMI during summer, as well as between humidity and EMI at both measured distances.
• Spatial mapping revealed the highest EMI values clustered centrally from the southern to the eastern northern regions at less than 20 meters distance, especially in winter.
• The observed clustering was strongly influenced by the geographical placement of the BTS.

Conclusion

The study emphasizes the importance of systematic EMI monitoring in urban regions due to the prevalence of values exceeding safety standards, underscoring a potential EMF-linked health risk for surrounding populations. The findings advocate for enhanced regulatory attention and targeted mitigation efforts in high-exposure zones.
