Impact Statement:
Take-Home Messages • Numerical dosimetry was useful to estimate the distribution of EMF in a realistic (V2V) communication scenario that includes realistic (for size, dimension, shape and materials) and accurate models of the car, the communicating antennas (four) and a human phantom. • Specific Absorption Rate (SAR) induced in the worst-case scenario was below the International Commission on Non-Ionizing Radiation Protection (ICNIRP) and IEEE 2019 limits for the general public in the 100 kHz-6 GHz band and was equal to 0.008 W/kg for the whole-body and 1.58 W/kg for local exposure (in the head); in all tested scenarios, the peak of SAR was located in the skin. • The biological target is the evaluation of SAR in a car passenger (adult driver) due to exposure to 5.9 GHz fields used in V2V communication. • This is the first study of RF exposure assessment in the novel scenario of V2V communication.
Abstract:
Cars are rapidly evolving into smart connected objects that can communicate not only with the infrastructure but also with other cars through vehicle-to vehicle (V2V) communication. By the end of 2023, more than 72 million vehicles worldwide will be equipped with devices and technologies that enable to exchange data and communicate with other cars. This challenging scenario is raising cross-cutting issues, such as those related to new radio-frequency exposures of the human body also when travelling. We evaluate the Specific Absorption Rate (SAR) induced in a realistic smart mobility communication scenario operated at 5.9 GHz. V2V antennas were modeled and placed on a realistic 3D model of a city-car to numerically estimate SAR in the body regions and tissues of a human phantom (adult male) inside the car. We found that both local and whole-body average exposures were below the ICNIRP and IEEE limits for the general public in the 100 kHz-6 GHz band, being equal in the worst case scenari...
