Oct 22, 2025
This randomized controlled pilot study examined whether short-term 5G mobile phone exposure (3.6 GHz; 0.0030 W/m2) affects corticospinal and intracortical excitability in 19 healthy adults. No significant exposure-by-time interactions were found for CSE, ICF, SICI, or LICI when comparing 5-minute, 20-minute, and sham…

This triple-blind randomized study tested whether 26.5 minutes of 26 GHz (5G) RF exposure at environmental-like levels alters salivary stress biomarkers in healthy adults. Salivary cortisol and alpha-amylase measured before, during, and after exposure did not differ between real and sham conditions. An exploratory…

This double-blind randomized sham-controlled repeated-measures study examined short-term 50 Hz ELF-EMF exposure (28 μT) to the chest and its effects on HR and HRV in 34 healthy young men. HR deceleration occurred in both EMF and sham conditions, but several HRV indices (SDNN, RMSSD, LF, HF) increased only in the EMF…

This study examined cardiovascular and microcirculation responses in healthy adults under zero magnetic field conditions generated by an "ARFA" magnetic field modeling facility. Participants were tested twice, once in zero magnetic field and once in a sham condition, with measures including capillary blood flow,…

Jan 1, 2014
The paper describes the development of RF-shielded hats using a microwave absorbing sheet intended to reduce EMF exposure to a cameraman’s head. Three hat designs are described, and measurements are planned/performed in an anechoic chamber using a wireless video camera operating around 1.9–2.7 GHz, including a 2.45…
