Radiofrequency Baseline Assessment of a Large Mining Concession Enclave and Affected Communities

Abstract

This study evaluated the existing RF levels within a gold mining concession before the planned installation of communication towers for a large-scale mining operation. Recorded power density levels ranged from 5.92 pWm-2 to 1.22 mWm-2, which are lower than those reported in similar studies. The highest total exposure levels were observed at some proposed tower locations, suggesting a potential increase in RF exposure at these sites once the communication towers are installed. This underscores the need for regulatory bodies to consider pre-existing RF exposure levels during the permitting process. Notably, higher power density levels were recorded in nearby towns. The 900 MHz band exhibited the highest power density, contributing 50% of the total exposure, indicating a prevalent use of 2G GSM900 mobile technology in the study area. Conversely, the mine’s designated communication frequency band recorded the lowest power density levels across all locations.
