Effects of extremely low-frequency electric fields at different intensities and exposure durations on mismatch negativity

Research RF Safe Research Library Jul 11, 2014

This rat study examined whether 50-Hz extremely low-frequency electric fields at 12 or 18 kV/m for 2 or 4 weeks affect mismatch negativity (MMN) and markers of oxidative damage/apoptosis in brain tissue. MMN amplitude was reported to be significantly reduced only in the 18 kV/m, 4-week exposure group versus the…

Occupational exposure to electromagnetic fields of uninterruptible power supply industry workers

Research RF Safe Research Library Jan 1, 2014

This workplace exposure assessment reports extensive spot measurements of ELF electric and magnetic fields in a UPS factory across test areas, production lines, and power substations. The highest fields were observed in test areas (up to 992.0 V/m and 215.6 µT). The authors state that measured levels were below…

[Objectivized evaluation of surgeons exposure to radiofrequency electromagnetic fields -- in the context of exposure duration and Polish and new international requirements regarding workers protection].

Research RF Safe Research Library Jan 1, 2013

This occupational exposure assessment monitored surgeons during 11 surgeries using monopolar electro surgery units and measured electric and magnetic field strengths during cutting and coagulating modes. Electric fields near the cable at 10 cm were reported in the hundreds of V/m, while magnetic fields were

Nanocomposite dielectrics in PbO-BaO-Na2O-Nb2O5-SiO2 system with high breakdown strength for high voltage capacitor applications.

Research RF Safe Research Library Jan 1, 2012

This engineering materials study reports fabrication and characterization of nanocomposite dielectrics in a PbO-BaO-Na2O-Nb2O5-SiO2 glass-ceramic system. X-ray diffraction and microstructural observations describe temperature-dependent phase formation with nanometer-sized crystallites dispersed in a glass matrix. The…

[Female genital toxicities of high-frequency electromagnetic field on rats].

Research RF Safe Research Library Jan 1, 2009

This rat study examined sub-chronic exposure to a 30 MHz electromagnetic field at 0–1600 V/m for 8 hours/day, 5 days/week, over 56 days. The authors report no change in ovarian wet weight, but dose-related changes in estrous cycle timing, reproductive hormones (higher LH and lower E2 at higher exposures), and ovarian…

[Assessment of radiofrequency electromagnetic fields levels in the Taranto area].

Research RF Safe Research Library Jan 1, 2007

This study reports punctual monitoring of RF electromagnetic fields from radiobase stations in the Taranto area, with measurement campaigns conducted from November 2005 to March 2007. Measurements covered 108 transmitting stations across multiple communication technologies within 100 kHz to 3 GHz. Most monitored…
