Radio-Frequency Electromagnetic Fields: Simultaneous exposure to infinite sources from typical base stations

This article shows that simultaneous exposure to infinite electromagnetic field (EMF) sources from typical base stations transmitting at multiple frequency bands is lower than international limits. Considering a real base station density and conservative path loss models, we show that the power density at a given location can be modeled by a convergent infinite series. To validate this model, we apply it to Brasília, Brazil, and compare the results with measurements. While the proposed model shows that the exposure ratio (ER) will not exceed 2.62%, the highest measured value reaches 85% of this estimation.
