This study reports measurements of electric field intensity (E) and magnetic flux density (B) from electric vehicles (inside driver/passenger seats during driving) and EV supply equipment (near chargers during charging) up to 400 kHz in and around Chennai. E and B inside EVs and E around EVSEs were reported to be within ICNIRP/IEEE guideline limits. However, B around certain EVSE positions reportedly exceeded a general public threshold (~200 T), and a preliminary FEM analysis suggested relatively higher fields at charging infrastructure. The authors call for further research on long-term health impacts and recommend policy actions to mitigate exposure.
Bus-exposure matrix, a tool to assess bus drivers' exposure to physicochemical hazards
This paper describes the development of a Bus-Exposure Matrix (BEM) to retrospectively estimate Swiss bus drivers’ exposures to 10 physicochemical hazards, including electric and magnetic fields. Measurements in representative buses were combined with technical inventories and INLA modeling to estimate annual exposures from 1985–2022. Reported trends include increasing peak noise and electric-field exposures over time, alongside decreases in several air pollution, vibration, and noise metrics.
Assessment of RF EMF Exposure to Car Driver from Monopole Array Antennas in V2V Communications Considering Thermal Characteristics
This modeling study assessed RF-EMF exposure from a 5.9 GHz V2V monopole array antenna integrated into a car roof shark-fin antenna. Using COMSOL simulations with an adult male body model inside a vehicle, the authors estimated localized and whole-body SAR and associated core temperature rise over a 30 min averaging period. Reported SAR and temperature rise values were below ICNIRP occupational thermal-based restrictions, leading the authors to conclude the exposure does not pose a threat under the studied conditions.
