摘要：

This paper proposes to complement the current regulatory agencies’ methodology for evaluating exposure to Radiofrequency Electromagnetic Fields (RF-EMF) in buildings under the direct incidence of emissions from Base Station (BS) antennas. The key contribution is the refinement of measurement point selection within buildings, ensuring that assessments more accurately capture exposure levels. The approach employs technical criteria for selecting target buildings, considering the location of the BSs and the configuration of the surrounding antenna structures. The proposed approach was applied to measurements in four buildings in the city of Natal, the capital of Rio Grande do Norte, located in the Northeast region of Brazil. The results show electric field intensity peaks up to 17.40 times higher and averages up to 14.13 times higher than values obtained from measurements conducted at ground level, such as those carried out by the National Telecommunications Agency (ANATEL). The highest exposure rates reached 82.27% and 59.43% of the limits established by the International Commission on Non-Ionizing Radiation Protection (ICNIRP) for the frequency bands of FM radio and mobile telephony, respectively. Our proposal can improve and complement the normative guidelines for RF-EMF exposure assessment, providing more representative evaluations of exposure in indoor building environments near modern telecommunication infrastructure. © 2025 Elsevier B.V.
