The neural network model predicted median and 95th percentile exposure levels with root-mean-square errors below 0.173 V/m and R2 values above 95%. Validation with measurements in three industrial environments showed an average absolute deviation of 20.4%.
Primary rat cortical astrocytes and human SH-SY5Y neuroblastoma cells were exposed to 5G-modulated 700 MHz RF-EMF at SARs of 0.08 W/kg and 4 W/kg for 1 h or 24 h under isothermal conditions. No statistically significant differences versus sham controls were d…
Exposure to 4.0 GHz RF at specified electric field amplitudes did not produce statistically significant reductions in bovine coronavirus survival compared to controls. Results suggest lower efficacy of viral inactivation at this frequency relative to higher f…
Using field-circuit coupling numerical simulations near a 200 kVA three-phase transformer, the maximum exposure occurred for a simulated patient directly beneath the transformer. Cardiac-tissue Bmax and Emax were reported to be below ICNIRP public exposure li…
No statistically significant changes in tumor incidence or survival rates were observed. No significant RF-related effects were detected in heart, brain, or adrenal glands. No changes in body temperature. Genotoxicity tests showed no evidence of DNA damage or…
Exposure to 50 Hz ELF magnetic fields at 200 µT for 2 or 24 hours showed no significant effects on cell viability, DNA integrity, or chromosomal distribution in human skin cells.
In a randomized, triple-blind crossover study (real vs sham), 26 GHz exposure at 2 V/m for 26.5 minutes did not significantly modulate EEG power spectral density in delta, theta, alpha, or beta bands across temporal phases and electrode clusters under eyes-cl…
In a triple-blind randomized protocol, acute 26 GHz 5G RF exposure (26.5 min) at 2 V/m (head) and 1 V/m (torso) showed no significant differences versus sham in salivary cortisol or alpha-amylase measured before, during, and after exposure. An exploratory sub…
In male Hsd:Sprague Dawley rats exposed to 900 MHz CDMA-modulated RF-EMFs at whole-body SAR 4 W/kg for 18 h 20 min/day over 2 years, there were no statistically significant increases in neoplastic or non-neoplastic lesion incidences in major organs. Genotoxic…
COMSOL multiphysics electromagnetic-thermal coupling simulations at 900, 2600, and 3500 MHz found a maximum SAR of 5.55 × 10-4 W/kg in the trunk at 3500 MHz. Tissue temperatures reached thermal steady state after 30 min; the maximum temperature rise was 0.212…
In 62 patients receiving ultrasound-guided supraclavicular brachial plexus block with lidocaine and levobupivacaine, dexmedetomidine 0.5 µg/kg given perineurally versus intramuscularly produced comparable onset and duration of sensory and motor blockade. The …
In a year-long frequency-selective measurement campaign in the Peloponnese Region of Greece, all measured electric field values were well below Greek safety limits; the highest ground-level measurement was about 18 times lower than the limit. The 900 MHz band…
A vibrating intrinsic reverberation chamber (VIRC) was implemented inside a walk-in plant growth chamber and enabled real-time monitoring of electric field parameters within a defined working volume. The electric field in the VIRC was reported as stable and s…
Ambient RF-EMF exposure was characterized in 15 operating rooms during 67 surgical procedures (120 h 45 min). The highest recorded mean value was 58.82 μW/m on the 2.4 GHz Wi‑Fi band. In all operating rooms, exposure remained below 0.4% of the ICNIRP (2020) r…
Over 1 year of monitoring in a nuclear medicine department, results from electronic personnel dosimeters, radon gas measurements, and electric field (EMF) measurements were reported to be far below national and international legal dose limits.
Numerical simulations at 5.9 GHz estimated that both localized and whole-body 30 min average SAR values were below ICNIRP occupational restrictions (100 kHz to 6 GHz). In the worst-case scenario, head SAR was 0.981 W/kg and whole-body average SAR was 0.008728…
In fibroblasts and keratinocytes exposed to electromagnetic fields described as within the 5G band (up to ten times permissible limits) for 2 hours or 48 hours, observed differences in gene expression and DNA methylation were minor and consistent with random …
In human neuroblastoma cell cultures, 3 h exposure at 26.5 GHz (SAR 1.25 W/kg) produced no effects on cell cycle or DNA damage under either continuous wave or 5G-modulated signals. No effects were observed when exposure was combined with menadione.
Spot measurements in line-of-sight to 56 active 5G macro base stations at 30 UK public locations found total RF and 5G-specific power density levels well within the 1998 ICNIRP public reference levels, including extrapolation to a stated worst-case scenario. …
Using SEER 22 data (2000–2021), malignant brain tumor incidence in adolescents and adults decreased (APC -0.6; p=0.0004), while benign brain tumor incidence increased (APC 1.9; p=0.00003). Temporal lobe tumors showed no significant change (APC -0.06; p=0.551)…
