“…The anatomical characteristics of the road user directly impact SAR wb . These characteristics include factors such as gender, body size, and age (as evidenced for example in [ 23 , 24 , 25 , 26 ]). On the other hand, the urban layout and the operational conditions of the V2V antennas have a more global impact on E inc , which in turns affects SAR wb .…”

This paper assessed the variability of radiofrequency exposure among road users in urban settings due to vehicle-to-vehicle (V2V) communication operating at 5.9 GHz. The study evaluated the absorbed dose of radiofrequencies using whole-body specific absorption rate (SAR) in human models spanning different age groups, from children to adults. To overcome limitations of previous studies, we developed a novel hybrid procedure that combines deterministic and stochastic approaches, enabling assessment across multiple urban layouts. Real urban conditions and varying propagation scenarios were considered in SAR calculations. By varying the road user’s position within 1.5–300 m from transmitting cars, the SAR distribution was determined. Median SAR remained consistently low, around 0.70 mW/kg, even with multiple transmitting cars and multiple emitting antennas, using maximum power allowed in US (44.8 dBm). The 99th percentile of SAR distribution varied based on body mass, decreasing for heavier models (typically adults) and increasing with the number of transmitting cars and antennas. The highest absorbed dose (73 mW/kg) occurred in a child model. The SAR consistently remained below the 80 mW/kg limit for whole-body exposure to electromagnetic fields in the 100 kHz–300 GHz range.

“…Future studies will be focused on the development of more sophisticated methods using stochastic and machine learning approaches for evaluating the exposure variables (i.e., specific absorption rate and absorbed power density) and exposure variability at RF and mm-Waves frequency ranges, considering an ever-increasing number of factors that can influence the exposure scenarios (e.g., the simultaneous presence of several sources operating at different frequencies, the morphology, the posture of the subject, etc.) [52], [53].…”
