Ambient RF-EMF exposure in surgical operating rooms from telecommunication antennas and Wi-Fi sources

Research PubMed: RF-EMF health Jan 22, 2026

This PubMed-listed study measured ambient radiofrequency electromagnetic field (RF-EMF) levels during surgical operations in 15 hospital operating rooms in Albacete, Spain, focusing on contributions from telecommunication antennas and Wi‑Fi. Using an exposimeter logging every 5 seconds across 67 procedures (~120 hours), the authors report that observed ambient RF‑EMF levels were comparable to other European indoor microenvironment studies. They report exposures in all operating rooms remained below 0.4% of the ICNIRP (2020) reference level, with the highest recorded mean value on the 2.4 GHz Wi‑Fi band.

Evaluation of Exposure Assessment Methods and Procedures for Induction Hobs (Stoves)

Research RF Safe Research Library Jan 1, 2025

This exposure-assessment study evaluated magnetic-field and contact-current exposures from modern induction hobs using IEC-based measurement procedures, 3D field scanning, and numerical dosimetry in anatomical models. It reports large between-hob variability in exposure and states that IEC 62233 may substantially underestimate user exposure. The authors argue that design modifications can reduce exposure and that product standards should be revised to better reflect realistic user scenarios.

Assessing exposure from different vehicular antennas in military applications: a computational study

Research RF Safe Research Library Jan 1, 2025

This computational study modeled electromagnetic exposure for military personnel near vehicular communication antennas across HF, VHF, and UHF scenarios. All simulated configurations reportedly met ICNIRP Basic Restrictions, though some exceeded ICNIRP Reference Levels in certain positioning and frequency combinations. The authors conclude that safety is generally maintained across the modeled conditions and that results can inform operational guidance and safety regulations.

Magnetic Field Measurement of Various Types of Vehicles, Including Electric Vehicles

Research RF Safe Research Library Jan 1, 2025

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.

Auto-Induced Downlink Radiofrequency Electromagnetic Field Exposure at 3.5 GHz With Focusing Near the Head

Research RF Safe Research Library Jan 1, 2025

This exposure-assessment study uses FDTD simulations to evaluate auto-induced downlink RF-EMF exposure at 3.5 GHz when downlink energy is focused toward user equipment near the head. Exposure varied substantially by device position (ear, eyes, nose) and by the precoding technique used. The authors report that the choice of normalization strategy can produce cases where ICNIRP basic restrictions are exceeded even when reference levels appear compliant, motivating a precautionary framing for compliance assessment.
