Intercomparisons of computed epithelial/absorbed power density & temperature rise in anatomical human face models under localized exposures at 10 & 30 GHz

Research RF Safe Research Library Jan 1, 2025

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…

Behaviour and reproduction of Drosophila melanogaster exposed to 3.6 GHz radio-frequency electromagnetic fields

Research RF Safe Research Library Jan 1, 2025

This animal study assessed whether 3.6 GHz RF-EMF exposure affects behaviour and reproduction in adult Drosophila melanogaster, using micro-CT-based digital-twin dosimetry and numerical simulations. It reports no significant changes in locomotor activity after 5 days at 5.4–9 V/m and no effect on fecundity over 48…

Investigation of fetal exposure to electromagnetic waves between 2.45 and 5 GHz during pregnancy

Research RF Safe Research Library Jan 1, 2025

This dosimetry study simulated fetal RF-EMF exposure between 2.45 and 5 GHz during the second trimester, estimating SAR10g in fetal brain and lungs. The presence of a belly-button piercing increased SAR, with maxima reported at 2.45 GHz (16 mW/kg in lungs; 14 mW/kg in brain). Despite these increases, all SAR values…

Dosimetric Electromagnetic Safety of People With Implants: A Neglected Population?

Research RF Safe Research Library Jan 1, 2025

This dosimetric study evaluated whether existing EM safety guidelines protect individuals with conductive implants by assessing implant-related local field enhancements. Across 10 kHz to 1 GHz, the authors report large increases in psSAR10mg and local electric fields near implants, particularly below 100 MHz. In…

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…

Assessment of spatial-average absorbed power density and peak temperature rise in skin model under localized electromagnetic exposure

Research RF Safe Research Library Jan 1, 2025

This numerical dosimetry study modeled localized RF exposure (3–30 GHz) in multi-layer human skin constructs including skin, fat, and muscle, with an added synthetic blood vessel model. Vascular modeling had negligible impact on peak spatial-averaged absorbed power density and a modest impact on peak temperature rise…

In situ electric field dosimetry analysis for powerline frequency peripheral nerve magnetic stimulation

Research RF Safe Research Library Jan 1, 2025

This study used computational dosimetry to analyze induced electric fields in a realistic human body model for a 60 Hz magnetic-field exposure system targeting the leg. Simulations indicated high EF intensities in several leg nerves and modeled conditions consistent with possible peripheral nerve stimulation. The MRG…

Assessment of Electromagnetic Exposure to a Child and a Pregnant Woman Inside an Elevator in Mobile Frequencies

Research RF Safe Research Library Jan 1, 2025

This study uses anatomically detailed computational models of a five-year-old girl, a pregnant woman in the third trimester, and a fetus to simulate mobile phone RF exposure inside an elevator cabin. Simulations at 1000 MHz and 1800 MHz across 48 configurations evaluated SAR10g, whole-body SAR, and maximum…

Impact of Anthropomorphic Shape and Skin Stratification on Absorbed Power Density in mmWaves Exposure Scenarios

Research RF Safe Research Library Jan 1, 2025

This dosimetry study used FDTD simulations at 28 GHz to evaluate how skin stratification and anthropomorphic modeling affect absorbed power density (APD) estimates. APD was higher with stratified skin than with homogeneous skin for a wearable patch antenna (16%–30% higher), while plane-wave differences were smaller (

Perspectives on terahertz honeybee sensing

Research RF Safe Research Library Jan 1, 2025

This paper describes measurements and simulations to support terahertz (THz) sensing of European honey bees for environmental monitoring. It reports dielectric characterization of bee body parts across 1–500 GHz, scattering-based validation of 3D-printed bee mockups, and THz imaging demonstrating detailed anatomical…

The specific absorption rate in different brain regions of rats exposed to electromagnetic plane waves.

Research RF Safe Research Library Jan 1, 2019

This study develops a numerical voxel rat model with 10 segmented brain regions to evaluate region-specific dosimetry under plane-wave EMF exposure. It reports that brain-region averaged SAR varies with frequency, incidence direction, and E-polarization direction. The authors also report potentially large deviations…

[Study of the influence of uniform transverse magnetic field on the dose distribution of high energy electron beam using Monte Carlo method].

Research RF Safe Research Library Jan 1, 2014

This engineering/medical physics study used Monte Carlo simulations to examine how a uniform transverse magnetic field affects the dose distribution of a 30 MeV electron beam in a water phantom. The abstract reports substantial changes in depth-dose, including reduced range and a pronounced end-of-range dose peak…

Assessment and comparison of total RF-EMF exposure in femtocell and macrocell base station scenarios.

Research RF Safe Research Library Jan 1, 2014

This study assessed and compared total RF-EMF exposure for a mobile-phone user in an office environment when connected to an indoor femtocell base station versus a conventional macrocell base station. Using a framework that combines near-field and far-field exposure, the authors report a 20–40× reduction in total…

Radiofrequency dosimetry in subjects implanted with metallic straight wires: a numerical study.

Research RF Safe Research Library Jan 1, 2008

This numerical FDTD study modeled RF exposure at 900 and 1800 MHz in tissue containing thin metallic straight wire implants. The model indicates that the wire can substantially increase local SAR, creating high SAR gradients. Despite this, the authors report that exposures below current safe levels resulted in…
