Electromagnetic Exposure from RF Antennas on Subway Station Attendant: A Thermal Analysis

Research PubMed: RF-EMF health Jan 28, 2026

This paper reports a multiphysics electromagnetic–thermal simulation of radiofrequency (RF) antenna exposure for a subway station attendant, estimating specific absorption rate (SAR) and temperature rise in the trunk and selected organs at 900, 2600, and 3500 MHz. Using a COMSOL-based model with a detailed human anatomy representation, the authors found simulated SAR and temperature increases that they state are well below ICNIRP occupational exposure limits. The study concludes that RF emissions from antennas in the modeled subway environment pose low health risk for female attendants with similar characteristics to the model used, while noting the work is based on simulations rather than measurements.

Female Crabs Are More Sensitive to Environmentally Relevant Electromagnetic Fields from Submarine Power Cables

Research RF Safe Research Library Jan 1, 2025

This controlled laboratory study examined sex-specific behavioral responses of juvenile shore crabs to magnetic fields intended to represent submarine power cable EMFs. Females showed consistent attraction to EMF-exposed zones across 500–3,200 μT exposures, whereas males showed no consistent spatial preference. The authors suggest such sex-specific sensitivity could disrupt female-driven behaviors relevant to migration and reproduction, with potential ecological implications.

Effect of Static Electromagnetic Field on Growth Parameters, Survival Rate, Sex Distribution, Ratio, and Liver and Gonadal Health of Zebrafish

Research RF Safe Research Library Jan 1, 2025

This animal study exposed zebrafish embryos to static electromagnetic fields for 63 days post-hatching across aquariums positioned 30–99 cm from the source, with an EMF-free control. The abstract reports strong shifts in sex distribution (including 100% female at the closest distance), markedly reduced survival in exposed groups, and histological liver and gonadal damage. The authors frame the findings as evidence of potential ecological risk via disrupted sex ratios and compromised health.

Characterization of the Core Temperature Response of Free-Moving Rats to 1.95 GHz Electromagnetic Fields

Research RF Safe Research Library Jan 1, 2025

This animal study measured core body temperature in free-moving male and female Sprague Dawley rats during and after 3-hour exposure to 1.95 GHz RF-EMF at multiple whole-body average SAR levels. A measurable thermal response was reported at 4 W/kg, while lower SAR conditions showed smaller or no significant temperature increases. The authors note that temperature dropped quickly after exposure ended, implying post-exposure measurements may underestimate peak heating.

Effects of non-ionizing radiation on the thyroid gland in rats

Research RF Safe Research Library Jan 1, 2025

This animal study exposed Sprague-Dawley rats (including pregnant females and offspring) to 2.45 GHz Wi-Fi or mobile jammer radiation for 2 hours daily over two weeks and assessed thyroid hormones and thyroid histology. The abstract reports significant changes in T4 in exposed adult males and significant differences in T3 among male offspring exposed to jammer radiation. Histopathology reportedly showed disrupted thyroid follicular structure in exposed rats. The authors conclude these findings support a potential link between non-ionizing radiation exposure and altered thyroid endocrine and histological parameters.

Effects of 700MHz radiofrequency radiation (5G lower band) on the reproductive parameters of female Wistar rats

Research RF Safe Research Library Jan 1, 2025

This animal study examined short- and long-term 700 MHz (lower-band 5G) radiofrequency exposure in female Wistar rats, comparing control, sham, and exposed groups. It reports no DNA damage and no change in estrous cycle length, but increased ovarian oxidative stress markers in exposed animals. Long-term exposure was associated with ovarian histopathological alterations, while estradiol and progesterone stayed within normal ranges and testosterone increased slightly but significantly.

Effect of Repeated Exposure to Complexly Organized Electromagnetic Radiation on the Rat Behavior in the "Open Field" Test

Research RF Safe Research Library Jan 1, 2024

This animal study examined repeated pulsed-modulated RF exposure (1–4 GHz; total pulse power density 300 μW/cm2) in male and female Wistar rats and assessed behavior using the open field test. The abstract reports stress reactions and long-term memory impairment in some rats, with females described as more sensitive than males. Reported effects were transient, with behavior returning to baseline within 1.5–2 months after exposure stopped. The authors suggest potential concern for constant exposure scenarios, though this is not directly evaluated in humans here.

Toxicology and carcinogenesis studies in Sprague Dawley (Hsd:Sprague Dawley SD) rats exposed to whole-body radio frequency radiation at a frequency (900 MHz) and modulations (GSM and CDMA) used by cell phones

Research RF Safe Research Library Jan 1, 2018

This National Toxicology Program technical report describes 900 MHz whole-body RFR exposures (GSM and CDMA) in male and female Sprague Dawley rats from in utero through up to 2 years. The report concludes clear evidence of carcinogenic activity in males for both modulations based on malignant schwannoma of the heart, with malignant glioma of the brain also reported as related to exposure. In females, the report concludes equivocal evidence of carcinogenic activity for both modulations based on selected tumor outcomes, and genetic toxicology findings were mixed with some comet assay increases/equivocal results but negative micronucleus assays.

Effects of GSM modulated radio-frequency electromagnetic radiation on permeability of blood-brain barrier in male & female rats

Research RF Safe Research Library Jan 1, 2016

This rat study examined whether pulse-modulated 900 MHz and 1800 MHz RF exposure affects blood-brain barrier permeability using Evans blue dye. The abstract reports increased permeability in male rats at both frequencies (stronger at 1800 MHz) and in female rats at 900 MHz but not at 1800 MHz. The authors suggest mobile-phone-like RF exposure could increase blood-brain barrier permeability under non-thermal conditions, while noting that further mechanistic studies are needed.

Effects of radiofrequency radiation exposure on blood-brain barrier permeability in male and female rats

Research RF Safe Research Library Jan 1, 2011

This rat study tested whether acute exposure to 0.9 and 1.8 GHz continuous-wave radiofrequency radiation alters blood-brain barrier permeability. Using Evans-blue/albumin as a tracer, the authors report no BBB leakage in exposed female rats but a significant increase in albumin in exposed male rat brains versus sham. The authors interpret this as suggesting BBB/vascular permeability changes in males at SAR levels stated to be below international limits.

The effects of microwave emitted by cellular phones on ovarian follicles in rats

Research RF Safe Research Library Jan 1, 2009

This animal study examined whether prenatal exposure to mobile phone microwaves affects ovarian development in rats. Pregnant rats were exposed to a phone placed under the cage throughout pregnancy, with mostly standby exposure and brief periodic speech-mode exposure. Female pups assessed at 21 days had fewer ovarian follicles in the exposed group than in controls, which the authors interpret as a toxic effect on ovaries.
