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…

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…

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

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…
