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.
Mechanism first explanation of how the plasma membrane potential controls immune responses
An RF Safe article argues that plasma membrane potential (Vm) is a key control variable for immune cell behavior by shaping ion driving forces, especially Ca2+ influx through CRAC channels and K+ channel–mediated hyperpolarization. It describes proposed links between Vm-regulated ion flux and downstream immune functions such as T-cell activation (NFAT/NF-κB signaling), macrophage polarization, respiratory burst capacity, and NLRP3 inflammasome activation. The piece also mentions that external electric fields can influence T-cell migration and activation markers under some conditions, but it does not present new experimental data in the excerpt provided.
Magnetic Field Measurement of Various Types of Vehicles, Including Electric Vehicles
This exposure assessment measured magnetic fields inside modern Japanese EVs, PHEVs, and ICEVs during actual driving using methods aligned with IEC 62764-1:2022. All measured magnetic flux density values were reported to be below ICNIRP public exposure reference levels. The study mapped in-cabin field sources and noted methodological differences may explain higher transient spikes reported in some international studies.
Analysis of Human Exposure to Electric and Magnetic Fields While Charging and Driving an Electric Vehicle
This paper describes planned experimental measurements of electric and magnetic fields generated by electric vehicles during charging and driving. The abstract emphasizes that occupants can experience notable EMF exposure due to proximity to vehicle electrical systems, while stating that specific health risks in the EV context remain uncertain. It also notes that manufacturers implement technological design solutions intended to reduce exposure.
