Flora and fauna: how nonhuman species interact with natural and man-made EMF at ecosystem levels and public policy recommendations
Research
RF Safe Research Library
Jan 1, 2025
This review discusses how increasing ambient nonionizing EMF (0–300 GHz), particularly RF from modern wireless technologies and satellites, may affect flora and fauna at ecosystem levels. It states that many nonhuman species rely on electro/magneto-reception and that even low-intensity EMF exposures are capable of…

Research
RF Safe Research Library
Jan 1, 2025
This narrative review discusses proposed non-thermal mechanisms by which chronic, low-intensity RF-EMR from ubiquitous wireless sources may affect male reproductive health. It highlights oxidative stress, mitochondrial dysfunction, impaired testosterone synthesis/steroidogenesis, and declines in sperm quality as…

Research
RF Safe Research Library
Jan 1, 2025
This conference paper uses COMSOL Multiphysics simulations to evaluate thermal and SAR-based exposure limits for modeled human skin exposed to terahertz radiation (0.1–5 THz). The authors report negligible temperature increases at power densities consistent with keeping SAR below 1.6 W/kg, but note that higher power…

Jan 1, 2025
This review discusses recent studies on microwave and RF exposure and their reported impacts on molecular and cytogenetic materials. It states there is growing evidence that RF exposure can induce DNA damage at levels considered safe by current standards, and cites newly reported genetic alterations in rat cancers…
Building the gulf of opinions on the health and biological effects of electromagnetic radiation
Research
RF Safe Research Library
Jan 1, 2025
This narrative article examines how opposing views formed regarding health and biological effects of electromagnetic radiation, focusing on ELF and RF exposures. It highlights historical controversies (e.g., childhood leukemia and ELF fields) and disputes over thermal versus non-thermal effects and reliance on SAR.…
Impact of Radiofrequency Electromagnetic Fields on Cardiac Activity at Rest: A Systematic Review of Healthy Human Studies
Research
RF Safe Research Library
Jan 1, 2025
This systematic review evaluated evidence on RF-EMF exposure and cardiac activity (heart rate and heart rate variability) in healthy humans at rest. Across 28 studies spanning 100 to 110,000 MHz and exposures from minutes to a week, most studies reported no significant effects on resting heart rate, and HRV findings…
Human achromatic flickers and phosphenes thresholds under extremely low frequency electric stimulations

RF Safe Research Library
Jan 1, 2025
This study estimated thresholds and locus for human phosphene perception during non-invasive transcranial alternating current stimulation at 20, 50, 60, and 100 Hz. Perception depended significantly on stimulation intensity, with the lowest threshold at 20 Hz and no reported phosphenes at 100 Hz. The authors report…

Research
RF Safe Research Library
Jan 1, 2025
This review discusses the rapid deployment of 5G and the associated debate about potential human health impacts from EMF exposure, particularly at 3.5–26 GHz including millimeter waves. It emphasizes limited published studies in these exposure ranges and highlights EU-funded initiatives and research consortia aimed…
SAR thresholds for electromagnetic exposure using functional thermal dose limits.
Research
RF Safe Research Library
Jan 1, 2018
This paper analyzes how conservative current localized RF EMF SAR basic restrictions may be by estimating the implied safety factor. The authors derive thermal dose–functional SAR limits from literature-reported thresholds for acute local tissue damage and compare these to existing basic restrictions. They report…
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…
