Intercomparisons of computed epithelial/absorbed power density & temperature rise in anatomical human face models under localized exposures at 10 & 30 GHz
This dosimetry intercomparison evaluated epithelial/absorbed power density and temperature rise in two high-resolution anatomical human face models under localized antenna exposures at 10 and 30 GHz. The study reports a statistical correlation between spatially averaged absorbed power density and temperature rise when appropriate averaging is applied. Antenna type/configuration was identified as the dominant contributor to variability, exceeding differences from averaging methods or anatomical models.
Model Variability in Assessment of Human Exposure to Radiofrequency Fields
This review examines how variability in computational dosimetry models affects assessment of human RF exposure from MHz to terahertz frequencies, focusing on SAR, absorbed power density, and temperature rise. It reports that anatomical scaling and model choices can drive meaningful differences in predicted SAR (including higher values in children/smaller models), while temperature-rise predictions are especially sensitive to thermophysiological parameters and vascular modeling. The authors indicate that computed variability remains within ICNIRP/IEEE safety margins but argue that uncertainties warrant ongoing research and refinement as new technologies (e.g., 6G) emerge.
Assessment of Electromagnetic Exposure Levels for Humans from Electric Vehicle DC Charging Stations
This simulation study modeled EMF exposure from an electric vehicle DC charging pile transformer using adult and child human models at several distances and for in-vehicle occupants during charging. Reported peak B-field and E-field values at 0.1 m and modeled internal exposures decreased with distance and remained below stated ICNIRP occupational and public limits. Frequency comparisons (85–95 kHz) indicated decreasing B-field with higher frequency while E-field stayed relatively stable. The authors note the need for real-world measurement validation and further assessment in sensitive populations and multi-source settings.
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.
Standards: Exposure Limits for Brief High Intensity Pulses of Radiofrequency Energy Between 6 and 300 GHz
This standards-focused paper evaluates ICNIRP and IEEE (C95.1-2019) exposure limits for brief, high-intensity pulsed RF-EMF between 6 and 300 GHz, particularly when exposures vary within the 6-minute averaging window. Using numerical and analytical modeling with a one-dimensional thermal tissue model, it reports differences in protection against transient skin heating, with IEEE described as more conservative than ICNIRP. The authors propose an adjustment to pulse fluence limits to improve consistency of protection and note that nonthermal and thermoacoustic effects were not analyzed.
20 kHz Magnetic Field Emission of Induction Cooking Heaters
This exposure assessment measured 20 kHz magnetic field leakage from induction cooking heaters across four models and compared results with ICNIRP general public limits. The maximum reported magnetic flux density was 16 µT at a specified measurement point using two S-type pans. Field leakage depended on pan size and configuration, and finite element modeling was reported to align closely with measurements.
