Abstract

Radiofrequency (RF) electromagnetic field (EMF) exposure from wireless telecommunication base station antennae can lead to debates, conflicts or litigations among the adjacent residents if inappropriately managed. This paper presents a measurement campaign for the GSM band EMF exposure in the vicinity of 827 base station sites (totally 6207 measurement points) in Guangxi, China. Measurement specifications are designed for risk communication with the residents who previously complained of over-exposure. The EMF power densities with the global positioning system coordinate at each measured point were recorded. Compliance with the International Commission on Non-Ionizing Radiation Protection guidelines and Chinese environmental EMF safety standards was studied. The results show that the GSM band EMF level near the base stations is very low. The measurement results and the EMF risk communication procedures positively influence public perception of the RF EMF exposure from the base stations and promote the exchange of EMF exposure-related knowledge.

Main findings

A measurement campaign around 827 GSM base station sites (6207 measurement points) in Guangxi, China recorded RF EMF power densities with GPS coordinates. Reported GSM-band EMF levels near base stations were very low and were evaluated for compliance with ICNIRP guidelines and Chinese environmental EMF safety standards. The measurement results and risk communication procedures were reported to positively influence public perception and knowledge exchange regarding base-station RF EMF exposure.

Outcomes measured

RF EMF power density levels near GSM base stations
Compliance with ICNIRP guidelines
Compliance with Chinese environmental EMF safety standards
Public perception of RF EMF exposure (risk communication impact)

Limitations

Specific GSM frequencies and measurement instrumentation/method details are not provided in the abstract.
No quantitative exposure values or compliance margins are reported in the abstract.
The description of improved public perception is not quantified and may be context-specific.
