Researchers modeled radiofrequency exposure in an 11-year-old passenger from a 1.575 GHz positioning antenna mounted on an autonomous-driving electric vehicle. For the simulated configuration, peak 1 g SAR was 0.19 W/kg and the maximum modeled temperature rise was 0.55°C, both below commonly used international safety limits that the authors compared against.

Note: This is a computational exposure assessment of one modeled antenna, vehicle and child-passenger configuration. It did not measure exposure in children riding in real vehicles or test health outcomes.

"In this study, COMSOL Multiphysics is used to construct the models of an EV, a positioning antenna and a child human body, and the levels of electromagnetic exposure of a child passenger to the positioning antenna in AD are calculated."

"Based on the analysis of this study, no significant health effects on child passengers have been observed."

— Xuwei Dong et al. (study authors)

"The electromagnetic exposure levels of the child passenger calculated in this study are all lower than the safety limits defined by international authoritative institutions."
