Abstract

Overview

The study conducted large-scale field observations and monitoring of electromagnetic fields (EMFs) in Xiamen Island, focusing on the complexities of the electromagnetic environment (EME) in urban settings.

Findings

• Measured electric field intensity ranged between 0.32 V/m and 1.70 V/m.
• Magnetic flux density varied from 0.11 μT to 0.50 μT.
• Higher levels of electric and magnetic fields were found in areas with more electric power facilities and electronic equipment.
• Analysis showed that the radiation power of 2G mobile communications was higher than that of 3G and 4G.
• While 3G signals had more uniform coverage, 4G coverage is under development and expanding.

Conclusion

The study establishes a strong link between the distribution of electromagnetic radiation (EMR) sources and the complexity of urban EM environments. Notably, there is a noteworthy correlation between magnetic flux density and residential areas, as well as a significant relation between 2G and 4G radiation power and educational areas. These findings underscore potential health risks associated with EMF in densely populated urban environments.
